• Run shell script on Linux box from a shortcut/app in Android?

  - by melat0nin

  I have an Ubuntu box which runs XBMC, which crashes occasionally. Since I have no keyboard connected,I have to SSH in, kill xinit, then restart it. I was wondering if there's an elegant way of doing this from my Android tablet, so I don't have to go to my desktop PC. I've used ConnectBot and can log in, but typing is laborious, even using the edit keys to scroll back up through the buffer. It seems as though it should be possible to script this so that I can execute a shortcut, or at least select a predefined script to be executed. This would seem to have plenty of applications, and there could be a site of scripts - restart webserver, reboot, email logs etc

• find directories in the current directory, older than 5 days and archive them

  - by user197284

  This is basic questions. I need to find folders in the current working directory(not recursively) and if they are older than 5 days archive them. zip or tar.gz is fine. I can find the folders with following commands find ./ -maxdepth 1 -type d -mtime +5 And i know i can pass this output of the find using xargs. But i do not know how to archive with folder name intact. That is the directory test1 should be archived to test1.zip and directory "test2" should be archived to "test2.zip". Any inputs are welcome. Regards

• Looking for a powershell script that can pull a file from a set of PC's and FTP

  - by DangeRuss

  I'm looking to write a script (preferably powershell) that will essentially copy a file from a bunch of PC's and FTP it to a server. So the structure of the environment is that we have a file on multiple PC's (around 50 or so) that need to placed on a server. Sometimes one of the PC's may be turned off so the script would first need to ensure the PC is up and running (maybe a ping result), then it would need to go into a directory on that PC, pull a file off of it, rename the file, place into a source directory, then remove the file. Naming convention doesn't matter, but date/time stamp would be easiest. Ideally, it would be best to first move all the files to a source directory to save on FTP bandwidth, but since the files will be named the same, the files must be renamed during the move process. Move not copy because the directory needs to be empty so the file can be re-created the next day. So once moved to the source directory, now all the files need to be FTP'd to a server for processing. After all of this, we need to know which PC's on the list did not respond so we can manually retrieve the file so the script should output a file (txt is fine) that will show which PC's were offline. Everything is one domain and script will be run from an server with admin creds. Thank you!

• How do I list currently running shell scripts?

  - by Nick

  I think I have a shell script (launched by root's crontab) that's stuck in a loop. How do I list running scripts and how can I kill them? I'm running Ubuntu 9.04, but I imagine it's similar for all *nix systems...

• Programmatic, script-based, or command line method to change starting program for user on Windows Server 2000/2003?

  - by Joe Majsterski

  I have written an app that we want to distribute to a large number of customers to be used as the shell program when they log onto their server with a particular admin account. I have figured out how to change the starting program by going to Administrative Tools->Computer Management->System Tools->Local Users and Groups->Users, selecting the properties for the user, going to the Environment tab, and changing the program file name under "Starting program" to my new app. But is there a way I could do this with some code that could be sent out and run on all these servers?

• Script to restart BlackBerry services

  - by ICTdesk.net

  Can somebody give me a script advice/example of how to restart services? I have to restart 17 services, but the first 4 services have to be in the right order and after the restart command is given to one of the services, the next one should be started when the previous one is finished. I know I can restart a service by net command, and I can build a delay by for example a ping command that repeats for an x amount of times, but I never know in advance how long it is going to take for a service to restart. Thanks, Kindest regards, Marcel

• Remotely initiate windows updates

  - by TetraFlash

  I have a network with countless workstations on it and the windows updates are done through WSUS in push cycles to allow us to use a generic image and configuration and avoid network congestion. I have a number of workstations in storage that are connected once a month for a few days to recieve updates, however not all of them fall within their push cycle. I want to avoid going to each machine and clicking "check updates" as that would require me to connect a monitor, mouse and keyboard. Is there a way (preferably through powershell but im open minded) to initiate a check and install of updates on a remote system? Lets say for 1 system at a time right now, I can add a file reader and a look later. NOTE: the configuration of the WSUS server is above my pay grade, im simply being asked to ensure these machines are updated. Thanks for any help or hints

• Run a specific command from a directory

  - by Cameron Kilgore

  I have a bash script where I need to run an init utility within a directory with a configuration file defined. I don't think it's possible to explicitly tell the utility to run the file as an argument, so what I need to do is go to the directory with the config file, and then run the command. I have some logic in place, but its not working -- the utility never runs. Is there any way I can tell the script to go to this directory, and then run the script? cd /var/www/testing-dev.example.co eval "standardprofile"

• Install correct libraries depending on 64/32 bit

  - by Rich

  I am using Bash to install a customised version of JBoss, and one of the things I would like to do is install the correct version of the Apache Portable Runtime, which is a native binary. This script could be run on both 32 and 64 bit versions of RHEL. What are my options for identifying which version of the APR to install? I think we only have 32bit and x64-based systems here. I would still like to identify i64 systems so that the script can refuse to install on that type of machine. I am aware of using uname -m and grepping /proc/cpuinfo to find out, but was wondering which approach others would recommend?

• SHELL OR PERL QUESTION

  - by user150674

  I have a very large file, named 'ColCheckMe', tab-delimited, that you are asked to process. You are told that each line in 'ColCheckMe' has 7 columns, and that the values in the 5th column are integers. Using shell functions indicate how you would verify that these conditions were satisfied in 'ColCheckMe' K got this... nawk ‘ NF != 7 { Printf(“[%d] has invalid [%d] number of fileds\n”, FNR, NF) } $5 !~ /^[0-9]+$/ { Printf(“[%d] 5th field is invalid [%s]\n”, FNR, $5) }’ ColCheckMe Now, 2. In with the similar file, you are told that each value in column 1 is unique. How would I verify that? Also write a shell function that counts the number of occurrences of the word “SpecStr” in the file 'ColCheckMe' Any one can help in SHELL or everything including the first in PERL Scripting.

• SQL Injection Protection for dynamic queries

  - by jbugeja

  The typical controls against SQL injection flaws are to use bind variables (cfqueryparam tag), validation of string data and to turn to stored procedures for the actual SQL layer. This is all fine and I agree, however what if the site is a legacy one and it features a lot of dynamic queries. Then, rewriting all the queries is a herculean task and it requires an extensive period of regression and performance testing. I was thinking of using a dynamic SQL filter and calling it prior to calling cfquery for the actual execution. I found one filter in CFLib.org (http://www.cflib.org/udf/sqlSafe): <cfscript> /** * Cleans string of potential sql injection. * * @param string String to modify. (Required) * @return Returns a string. * @author Bryan Murphy ([email protected]) * @version 1, May 26, 2005 */ function metaguardSQLSafe(string) { var sqlList = "-- ,'"; var replacementList = "#chr(38)##chr(35)##chr(52)##chr(53)##chr(59)##chr(38)##chr(35)##chr(52)##chr(53)##chr(59)# , #chr(38)##chr(35)##chr(51)##chr(57)##chr(59)#"; return trim(replaceList( string , sqlList , replacementList )); } </cfscript> This seems to be quite a simple filter and I would like to know if there are ways to improve it or to come up with a better solution?

• Wordpress dynamic navigation function for highlighting single post tabs

  - by user269959

  I am trying to write a function that i can reuse in my wordpress themes that will allow me to build robust dynamic navigation menus. Here is what i have so far: function tab_maker($page_name, $href, $tabname) { //opens <li> tag to allow active class to be inserted if tab is on proper page echo "<li"; //checks that we are on current page and highlights tab as active if so if(is_page($page_name)){ echo " class='current_page_item'>"; } //closes <li> tab if not active else { echo ">"; } //inserts the link as $href and the name of the tab to appear as $tabname then closes <li> echo "<a href=$href>$tabname</a>"; echo "</li>"; } This code works as expected except i cant enable it to highlight for a single blog post as the page names are dynamic. I know about the wordpress function is_single() which ive used to implement this feature in previous nav menus but i cant find a way to integrate it into this function. appreciate any help!

• popup with dynamic menuitems, each menuitem is another popup

  - by encryptor

  I am building an extension that has a pop up whose elements are constructed by a function call everytime the mouse hovers over the popup option. I am able to achieve this. Now I need to have a popup for each of the menu item (inside the original popup) which is not dynamic though. I have this code, but it does not work: for (var m=0; m < localpubliclist.length; m++) { var newItem = document.createElement("menu"); newItem.setAttribute("label", publicdisplayname[m]); newItem.setAttribute("id", "public" + m); myMenuPopup.appendChild(newItem); var newpopup = document.createElement("menupopup"); newpopup.setAttribute("id","publicpop" + m); newItem.appendChild(newpopup); var new1= document.createElement("menuitem"); new1.setAttribute("label", "Home"); new1.setAttribute("id", "publichome" + m); newpopup.appendChild(new1); } doing this forms the first popup where i can see all my menu with names publicdisplayname[m]. each of these is to be a popup which displays "Home". This does not work. the second popup (popup on publicdisplayname[m]) does not open. i have been stuck on this for quite some time and have tried various things cut it doesnt work. Can we do this at all? can we have double dynamic popups?

• Difference dynamic static 2d array c++

  - by snorlaks

  Hello, Im using opensource library called wxFreeChart to draw some XY charts. In example there is code which uses static array as a serie : double data1[][2] = { { 10, 20, }, { 13, 16, }, { 7, 30, }, { 15, 34, }, { 25, 4, }, }; dataset->AddSerie((double *) data1, WXSIZEOF(dynamicArray)); WXSIZEOF ismacro defined like: sizeof(array)/sizeof(array[0]) In this case everything works great but in my program Im using dynamic arrays (according to users input). I made a test and wrotecode like below: double **dynamicArray = NULL; dynamicArray = new double *[5] ; for( int i = 0 ; i < 5 ; i++ ) dynamicArray[i] = new double[2]; dynamicArray [0][0] = 10; dynamicArray [0][1] = 20; dynamicArray [1][0] = 13; dynamicArray [1][1] = 16; dynamicArray [2][0] = 7; dynamicArray [2][1] = 30; dynamicArray [3][0] = 15; dynamicArray [3][1] = 34; dynamicArray [4][0] = 25; dynamicArray [4][1] = 4; dataset->AddSerie((double *) *dynamicArray, WXSIZEOF(dynamicArray)); But it doesnt work correctly. I mean point arent drawn. I wonder if there is any possibility that I can "cheat" that method and give it dynamic array in way it understands it and will read data from correct place thanks for help

• Change dynamic web reference from web./app.config

  - by Snæbjørn

  I have a problem changing a dynamic web reference in the config file. Changing the url in the config file doesn't have any effect. I have to change the url in .settings and compile for it to change. I added the web reference using the wizard. Set the URL behavior to dynamic, which added the relevant XML tags in config file. In my solution I have the web API (web reference) in a separate project (class lib), so I referenced the project and copied the <applicationSettings> over. <applicationSettings> <StartupProject.Properties.Settings> <setting name="WebReference" serializeAs="String"> <value>http://someurl/somefile.asmx</value> </setting> </StartupProject.Properties.Settings> </applicationSettings> Note that it's <StartupProject.Properties.Settings> and not <WebRefProject.Properties.Settings>. Are there some limitations I'm not aware of or am I doing something wrong?

• Who does non-decimal bignums with floating radix point?

  - by boost

  Nice as the Tcl libraries math::bignum and math::bigfloat are, the middle ground between the two needs to be addressed. Namely, bignums which are in different radices and have a radix point. At present math::bignum only handles integers (afaict) and math::bigfloat won't let you specify different radices to math::bigfloat::fromstr (ditto). Does anyone know of a library, for any of the major scripting languages (e.g. Tcl, Perl, Python, Ruby, Lua) or less major ones (newLISP for example), which implements bignums in different radices with handling for radix point?

• How do I prepare myself for a summer of working on Python using Linux environment?

  - by Shailesh Tainwala

  Hi, I have used just Windows for programming so far. Now, I have an internship starting in two weeks and I will be using just Linux environment with Python programming language. I've installed Ubuntu on my system but have no exposure to shell scripting. I need some advice on how I can quickly learn to use the Linux terminal quickly. Any books or web resources that you can suggest? Also, is there a particular IDE that is generally preferred for Python programming on Linux, or is Vim preferred? How can I best prepare myself for the internship ahead? Thanks for taking the time.

• Storing date and time as epoch vs native datetime format in the database

  - by zakovyrya

  For most of my tasks I find it much easier to work with date and time in the epoch format: it's trivial to calculate timespan or determine if some event happened before or after another, I don't have to deal with time-zone issues if the data comes from different geographical sources, in case of scripting languages what I usually get from database when I request a datetime-typed column is a string that I need to parse in order to work with it. This list can go on, but for me in order to keep my code portable that's enough to ditch database's native datetime format and store date and time as integer. What do you guys think?

• What language is to binary, as Perl is to text?

  - by ehdr

  I am looking for a scripting (or higher level programming) language (or e.g. modules for Python or similar languages) for effortlessly analyzing and manipulating binary data in files (e.g. core dumps), much like Perl allows manipulating text files very smoothly. Things I want to do include presenting arbitrary chunks of the data in various forms (binary, decimal, hex), convert data from one endianess to another, etc. That is, things you normally would use C or assembly for, but I'm looking for a language which allows for writing tiny pieces of code for highly specific, one-time purposes very quickly. Any suggestions?

• ffmpeg screen capture

  I wrote this script for some basic screen capture; it gets the window dimensions then uses the ffmpeg binary to record. I suspect there is a better way (maybe with the ffmpeg library), but scripting is what I know and ffmpeg generally works. Any software (other than recordmydesktop), or improvements to the script are welcome. info=`xwininfo -frame` H=`echo "$info" | grep Height | sed -E "s/^.*: ([[:digit:]]+)$/\1/"` W=`echo "$info" | grep Width | sed -E "s/^.*: ([[:digit:]]+)$/\1/"` offset=:0.0+`echo "$info" | grep Corners | sed -E "s/^.*:[[:space:]]+\+([[:digit:]]+\+[[:digit:]]+)[[:space:]]+.+/\1/" | tr + ,` /usr/local/bin/ffmpeg -f x11grab -s ${W}x${H} -r 45 -i $offset -sameq -f avi ~/videos/`date +%Y-%m-%d-%H%M%s`_vid & echo $! > /tmp/$(basename $0)-$USER
