• Problems with Startup after Script runs to Shutdown Windows 7 PC

  - by Toby Allen

  I have a simple .bat script to shutdown a kiosk style machine in our work shutdown -h -f this hibernates the machine and I have it running each evening as a scheduled job. However my problem comes when I turn the machine on again. The first time I press power it starts up and then immediately hibernates again, like it runs the script a second time. the second time I press power it stays up. Any suggestions on how I can avoid this?

• How to turn off Firefox forms autocomplete for only certain websites, or for all sites temporarily?

  - by Jason

  I want to turn off Firefox autocomplete, but only for specific websites--not for the entire interwebs. My language course has an online workbook, and the autocomplete keeps giving me the answers if I need to re-do an exercise. The tutorials I've found online all tell me to clear out my form history. I don't want to do this. I just want autocomplete to not work for a specific set of websites, or alternately turn it off temporarily. How can I do this?

• How to modify Chrome newtab.css from within a Chrome theme?

  - by user143423

  I want to modify the CSS for new tab page. NOT make new tab page. I already made a new tab page, but many users installing my themes won't also install the new tab page extension. So I want to modify the CSS on the new tab page for those who ONLY want my theme. It is my understanding that chrome://theme/css/newtab.css is the stylesheet I need to change. Feel free to tell other ways to add CSS to the ORIGINAL new tab page in Chrome.

• Tab Auto-Completion in Mac OS X when using sftp in terminal

  - by AlanTuring

  i have been getting very frustrated lately since the readline functionality has been removed from MacOSX and Tab Auto-Completion doesn't work anymore. So i was wondering if anyone knew a good alternative to use that i could install so i can tab auto-complete files when sftp'd in. I heard that with-readline is a good option for this. If so, how do i get an alias sftp = with-readline sftp to work? I would like to do the same with any other option that isn't with-readline, so i don't have to assign an alias each time i set up a session. I am using Mac OS X 10.8(Mountain Lion) with Homebrew installed. Thanks in advance to anyone who can help me.

• Using SSH, transfer webURL to remote machine

  - by AlanTuring

  Hi so i was doing some research in the library so i could use some pictures later on my Desktop computer in my room. I have space on my Lab account which i usually SSH into, and i was wondering if URL's can be directly transferred over to a remote machine and saved on the hard disk. I was thinking something like this: scp http://click.si.edu/images/truncatedurl.jpg /home3/etc.../filename.jpg is this possible? Thanks in advance.

• Mac OS X Lion and KeepassX

  - by Hallsie11

  I installed KeepassX on my new Mac which I am still learning the ropes on. I downloaded the program to allow autofill on Chrome ( KeePassHttp.plgx ). It says it needs to be put into directory of KeepassX, but I can't drag it into the application file and I'm not sure yet how to manipulate Terminal. Is terminal what I need to use or is there another way to put it in directory? At this point it is on the Chrome interface, but says it can't detect or make a connection with KX

• Is there a way to make IETab always open a site in Internet Explorer?

  - by reg

  Hello, IETab offers a setting that lets you define sites that should always be opened using IE's rendering engine. This is great and I use it all the time. There are a few sites, though, with which I encounter problems when I access them this way (needless to say that these have some IE-only features, otherwise I would simply use Firefox without IETab). So my question is: is there a way to make IETab (or any other extension that does the same thing) automatically open a specific list of sites in IE? To be clear: I want a way to specify a list of sites that will open an external IE process from Firefox, when clicking on those links or bookmarks from within Firefox.

• Accidental Extract Location - How to Clean Up?

  - by Gordon

  Sometimes I will do a command such as unzip tons_of_files.zip And I will forget to put a -d to point to a subdirectory. This causes the current folder to get filled with tons of files that are intermixed with the existing files. What is the best way to remove all these new files and/or move them to a new directory? I want to avoid having to manually examine the directory and determine if the file was part of the archive or was already present.

• UTF-8 locale portability (and ssh)

  - by kine

  I spend a lot of my time sshed into various machines, all of which are different (some are embedded, some run Linux, some run BSD, &c.). On my own local machines, however, i use OS X, which of course has a userland based on FreeBSD. My locale on those machines is set to en_GB.UTF-8, which is one of the available options: % echo `sw_vers` ProductName: Mac OS X ProductVersion: 10.8.2 BuildVersion: 12C60 % locale -a | grep -i 'en_gb.utf' en_GB.UTF-8 Several of the more-capable Linux systems i use appear to have an equivalent option, but i note that on Linux the name is slightly different: % lsb_release -d Description: Debian GNU/Linux 6.0.3 (squeeze) % locale -a | grep -i 'en_gb.utf' en_GB.utf8 This makes me wonder: When i ssh into a Linux machine from my Mac, and it forwards all of my LC_* variables with that 'UTF-8' suffix, does that Linux machine even understand what is being asked of it? Or is it just falling back to some other locale? In either case, what is the mechanism behind its behaviour, and is it dependent on any particular set-up (e.g., will i see the same behaviour on a BusyBox-based system as on a GNU-based one)?

• How to make Chrome open bookmarks and URLs in new tabs?

  - by MBraedley

  I principally use Firefox both at home and at work, but on occasion I use Chrome. I have Firefox working the way I like it by having it open bookmarks in a new tab when left clicked, as well, URLs open in new tabs. Although having URLs open in a new tab can be annoying if I type a bad URL, I still prefer it, but that's neither here nor there. I would like to replicate this behaviour in Chrome, and can't seem to find anything relavent in the settings. Is there any way of doing this without an extension? If not, can you point me towards an appropriate extension (I've already done a search and can't find what I'm looking for)?

• what to do when ctrl-c can't kill a process?

  - by Dustin Boswell

  Ctrl-c doesn't always work to kill the current process (for instance, if that process is busy in certain network operations). In that case, you just see "^C" by your cursor, and can't do much else. What's the easiest way to force that process to die now without losing my terminal? Summary of answers below: Usually, you can Ctrl-z to put the process to sleep, and then do "kill -9 process-pid", where you find the process's pid with 'ps' and other tools. On Bash (and possibly other shells) you can do "kill -9 %1" (or '%N' in general) which is easier. If Ctrl-z doesn't work, you'll have to open another terminal and kill from there.

• In Bash, how can I obtain the directory path from the previous command's last argument

  - by Beaming Mel-Bin

  I frequently have to do this. For example: $ vim /etc/pam.d/sudo $ vim /etc/pam.d/sudo-i $ cd /etc/pam.d/ # Figure I should just go to the directory Now, is there a way I could obtain the directory of the last argument when it's a file path? I'm asking this cause I recently became aware of the $_ variable that has become useful. Was wondering if there's some other commandline fu that might come in handy.

• Files copying between servers by creation time

  - by driftux

  My bash scripting knowledge is very weak that's why I'm asking help here. What is the most effective bash script according to performance to find and copy files from one LINUX server to another using specifications described below. I need to get a bash script which finds only new files created in server A in directories with name "Z" between interval from 0 to 10 minutes ago. Then transfer them to server B. I think it can be done by formatting a query and executing it for each founded new file "scp /X/Y.../Z/file root@hostname:/X/Y.../Z/" If script finds no such remote path on server B it will continue copying second file which directory exists. File should be copied with permissions, group, owner and creation time. X/Y... are various directories path. I want setup a cron job to execute this script every 10 minutes. So the performance is very important in this case. Thank you.

• Gmail - Ways to have more than 20 items per page in the search results

  - by Andrei

  Gmail has the notorious limitation of 20 results per page when searching your mail. Is there an extension (Chrome - preferable, Firefox, etc.) that can fix this (i.e. allow more than 20 items per page)? Based on my experience this should be entirely doable (have the extension move across pages in the background and then collect the results). Is there an extension that can already do this? I'm asking because I couldn't find one.

• How to permanently disable Firefox Flash plugin sound in Win 7 now that plugin-container.exe is here

  - by Subuser

  I want Flash to play without sound on my machine, and I want that preference to stick so that new sessions don't surprise me with sound. Using FlashBlock while trying to remember to disable sound every time a flash window is started doesn't do the trick for me -- it's too difficult to remember to check the mute status before and after playing videos. Previously, using Win 7 and Firefox, one could selectively disable sound from Flash plugins using the method described in this question. Older methods of disabling it included the plugin called FlashMute. FlashMute fails me even when this trick has been employed, and the volume method described in the previous question only works for the currently live session, resetting sound to maximum volume whenever the plugin container is restarted. What is the best way to disable Flash sound?

• PuTTY - Server Unexpectedly Closed Network Connection

  - by Austin

  I have two servers that I have been able to connect fine as s1.website.com and s2.website.com I connected to s1.website.com earlier today without any issues, however, when I connected to s2.website.com it gave me the "Server Unexpectedly Closed Network Connection" I have researched this elsewhere and someone concluded it to a "brute force attempt" However, I know this is not the case. If anyone else has had this issue please let me know. Thanks

• Cron process not starting

  - by vkris

  I have an ec2 image created with cron jobs. These jobs fail to run; I discovered the cron process in itself has not started. So, I included /usr/sbin/cron in /etc/rc.d/rc.local and created another image. But still for some reason the cron process does not start on bootup. If I restart the machine, the cron process runs. It doesn't run when it boots up! Any reason why this is happening? Also, is there any other alternatives for this ?

• Get a script to run at startup (linux)

  - by Dan Graves

  I am trying to get a simple script to run automatically at startup. A friend told me to do this but it did not work. Could someone take a look to see what it is missing? *(Also I am brand new to linux, so this is pretty foreign to me) Here is what I was told to do: In terminal sudo nano /etc/init.d/obabp.sh Then enter this text: #!/bin/bash sudo python /home/pi/gits/RPi-OBABP/src/obabp.py save file and then $ sudo chmod +x /etc/init.d/obabp.sh $ sudo shutdown -r now

• Unix: sleep until the specified time

  - by aix

  Is there a (semi-)standard Unix command that would sleep until the time specified on its command line? In other words, I am looking for something similar to sleep that would take wakeup time rather than duration. For example: sleeptill 05:00:00 I can code something up but would rather not re-invent the wheel if there's already something out there. Bonus question: it would be great if it could take the timezone (as in sleeptill 05:00:00 America/New_York). edit Due to the nature of what I am doing, I am looking for a "sleep until T" rather than "run command at T" solution. edit For the avoidance of doubt, if I run the command at 18:00 and tell it to wake up at 17:00, I expect it to sleep for 23 hours (or, in some corner cases having to do with daylight savings time, for 22 or 24 hours.)

• Connect to MySQL trough command line without need root password

  I'm building a Bash script for some tasks. One of those tasks is create a MySQL DB from within the same bash script. What I'm doing right now is creating two vars: one for store user name and the other for store password. This is the relevant part of my script: MYSQL_USER=root MYSQL_PASS=mypass_goes_here touch /tmp/$PROY.sql && echo "CREATE DATABASE $DB_NAME;" > /tmp/script.sql mysql --user=$MYSQL_USER --password="$MYSQL_PASS" < /tmp/script.sql rm -rf /tmp/script.sql But always get a error saying access denied for user root with NO PASSWORD, what I'm doing wrong? I need to do the same for PostgreSQL, any help? Regards and thanks in advance

• split a textfile after each n matches to a new file using sed or awk

  - by ozz

  i tried to split a file in parts of n matches each. The file is just one line and the seperator is '<br>' foo<br>bar<br>.....<br> I just want to split the file in parts, where each file has 100 datasets (text plus <br>)( normaly 100 datasets, but at the end maybe less) I already played around with this ... split-file-in-2-with-sed and this split-one-file-into-multiple-files-based-on-pattern sed.exe -e "^.*.<br>{0,100}/g" < original.txt > first_half.txt The split do not work an the result is only 1 file instead of many.

• How to execute a command whenever a file changes?

  - by Denilson Sá

  I want a quick and simple way to execute a command whenever a file changes. I want something very simple, something I will leave running on a terminal and close it whenever I'm finished working with that file. Currently, I'm using this: while read; do ./myfile.py ; done And then I need to go to that terminal and press Enter, whenever I save that file on my editor. What I want is something like this: while sleep_until_file_has_changed myfile.py ; do ./myfile.py ; done Or any other solution as easy as that. BTW: I'm using Vim, and I know I can add an autocommand to run something on BufWrite, but this is not the kind of solution I want now. Update: I want something simple, discardable if possible. What's more, I want something to run in a terminal because I want to see the program output (I want to see error messages). About the answers: Thanks for all your answers! All of them are very good, and each one takes a very different approach from the others. Since I need to accept only one, I'm accepting the one that I've actually used (it was simple, quick and easy-to-remember), even though I know it is not the most elegant.
