  • Accessing variable from ARGV

    - by snaken
    I'm writing a cPanel postwwwact script, if you're not familiar with the script its run after a new account is created. it relies on the user account variable being passed to the script which i then use for various things (creating databases etc). However, I can't seem to find the right way to access the variable i want. I'm not that good with shell scripts so i'd appreciate some advice. I had read somewhere that the value i wanted would be included in $ARGV{'user'} but this simply gives "root" as opposed to the value i need. I've tried looping through all the arguments (list of arguments here) like this: #!/bin/sh for var do touch /root/testvars/$var done and the value i want is in there, i'm just not sure how to accurately target it. There's info here on doing this with PHP or Perl but i have to do this as a shell script. EDIT Ideally i would like to be able to call the variable by something other than $1 or $2 etc as this would create issues if an argument is added or removed Any ideas?

  • What does /dev/null mean in a shell script?

    - by rishiag
    I've started learning bash scripting by using this guide: http://www.tldp.org/LDP/abs/abs-guide.pdf However I got stuck at the first script: cd /var/log cat /dev/null > messages cat /dev/null > wtmp echo "Log files cleaned up." What do lines 2 and 3 do in Ubuntu (I understand cat)? Is it only for other Linux distributions? After running this script as root, the output I get is Log files cleaned up. But /var/log still contains all the files.

  • User Guide to Dropbox Shared Folders

    - by Matthew Guay
    Dropbox is an incredibly useful tool for keeping all your files synced between your computers and the cloud.  Here we’re going to look at how you can keep all of your team on the same page with Dropbox shared folders. Creating a Shared Folder Setting up a shared folder in Dropbox is easy.  Add the files you want to share to a folder in Dropbox on your computer, then right-click in the folder, select Dropbox, and then choose Share This Folder.   Alternately, log into your Dropbox account online, click the drop-down menu beside the folder you want to share, and click Share this folder. Now, enter the email addresses of the people you want to share the folder with, and optionally enter a message explaining why you’re sharing the folder. The people you invite will receive an email inviting them to view and join the shared folder.  If they haven’t signed up for Dropbox, they can directly signup; otherwise, they can simply log into their Dropbox account and start adding or editing files. Shared folders have a slightly different icon in your Dropbox.  Notice the shared folder on the left has an icon with 2 people, while the folder on the right that is not shared, shows previews of its contents. See Your Shared Folder’s History Whenever your collaborators with your shared folders add or change files, you will see a tooltip notification telling you what changed. You can also view the changes online.  Log into your Dropbox account in your browser and select the Events tab.  This shows all changes to your Dropbox, but you can view only the changes in your shared folder by selecting its name on the left sidebar. Now you can see all recent changes to your folder, and can also see who added or removed each file.   On the bottom of the page, you can even add a comment that all the collaborators will see. If someone deleted a file you still need, you can restore it by clicking its link in this online history.  Or, you can view any deleted files by right-clicking in your Dropbox folder in Explorer.  Select Dropbox, and then click Show Deleted Files.   Get Notified When a Change is Made You’re not always in front of your computer; you’ve got a life beyond your projects, after all (at least hopefully).  If you really want to stay connected to what’s happening with your project, though, you can easily do that no matter where you are. Your shared Dropbox folder’s history page offers an RSS feed of all changes to the folder.  Click  the Subscribe to this feed hyperlink. Now, in the popup that opens, click “Copy to clipboard” so you can use this RSS feed. You can subscribe to RSS feeds through many web browsers, email clients, dedicated feed readers, and more.  In Firefox, Internet Explorer 7/8, or Opera, you can paste the feed address into your address bar and subscribe to the feed directly in your browser.   However, subscribing to the feed in a desktop application won’t help you much when you’re away from your computer.  One great option is to subscribe in the popular Google Reader.  Then you can check your feed from any browser, on any computer or mobile device. To add your Dropbox feed to Google Reader, log into Google Reader (link below), click Add a subscription on the top left, paste your RSS feed from Dropbox, and click Add.   Now you can see any changes to files or folders in Google Reader. You can even add your feed to your iGoogle homepage.  Click the Add it Now button on the right in the front page of Google Reader to add your feeds to iGoogle.   Now you can see updates on your files from your homepage.  If you’re using a different computer, just login to your Google account to see what’s happening. You can also access your Google Reader feeds from many programs and apps for most major Smartphones including iPhone, Windows Phone, and Blackberry. Receive a Tweet or Text When Changes are Made If you’re a hyper-connected individual, chances are you send and receive tweets on the go.  If so, this might be the best way for you to get notified when changes are made to your Dropbox shared folder.  To do this, first create a new Twitter account to publish your changes through.  If you don’t want the whole world to see your updates, click Settings and set your new Twitter account to Private. Once the new account is created, follow it with your normal Twitter account so you’ll see updates. Now, let’s publish our Dropbox RSS feed to Twitter.  Create an account with Twitterfeed (link below). Once your account is setup, add your feed to it.  Name your feed, and enter your Feed address from Dropbox.  Click Advanced Settings to make your feed work just like you want. In Advanced Settings, change the frequency to “Every 30 mins” to make sure you’re updated on changes as quick as possible.  You can also change other settings if you like. Click “Continue to Step 2”, and then click Twitter under the available services to add your account. Make sure your signed into your new Twitter account, and then click Authenticate Twitter. Allow the application. Now, finally, click Create Service. Whenever a change is made, you will receive a tweet via your new Twitter account.  And since you can receive tweets via text message or many mobile applications, you’ll never be very far away from your Dropbox changes!   Conclusion Dropbox shared folders are a great way to keep your whole team working together on the same files in a project.  And with these handy tricks, you can keep up with your shared files wherever you are! There are a lot of cool things you can do with Dropbox make sure to check out our posts on adding Dropbox to the Windows 7 Start menu, Accessing Dropbox files from Chrome, and Syncing your Pidgin Profile Across Multiple PCs.

  • How to resolve symbolic links in a shell script

    - by Greg Hewgill
    Given an absolute or relative path (in a Unix-like system), I would like to determine the full path of the target after resolving any intermediate symlinks. Bonus points for also resolving ~username notation at the same time. If the target is a directory, it might be possible to chdir() into the directory and then call getcwd(), but I really want to do this from a shell script rather than writing a C helper. Unfortunately, shells have a tendency to try to hide the existence of symlinks from the user (this is bash on OS X): $ ls -ld foo bar drwxr-xr-x 2 greg greg 68 Aug 11 22:36 bar lrwxr-xr-x 1 greg greg 3 Aug 11 22:36 foo -> bar $ cd foo $ pwd /Users/greg/tmp/foo $ What I want is a function resolve() such that when executed from the tmp directory in the above example, resolve("foo") == "/Users/greg/tmp/bar".

  • flush output in Bourne Shell

    - by n-alexander
    I use echo in Upstart scripts to log things: script echo "main: some data" >> log end script post-start script echo "post-start: another data" >> log end script Now these two run in parallel, so in the logs I often see: main: post-start: some data another data This is not critical, so I won't employ proper synching, but thought I'd turn auto flush ON to at least reduce this effect. Is there an easy way to do that? Update: yes, flushing will not properly fix it, but I've seen it help such situations to some degree, and this is all I need in this case. It's just that I don't know how to do it in Shell

  • Cheat sheet exhibiting bash shell stdout/stderr redirection behavior

    - by SetJmp
    Is there a good cheat sheet demonstrating the many uses of BASH shell redirection? I would love to give such a thing to my students. Some examples I'd like to see covered: cmd > output_file.txt #redirect stdout to output_file.txt cmd 2> output_file.txt #redirect stderr to output_file.txt cmd >& outpout_file.txt #redirect both stderr and stdout to output_file.txt cmd1 | cmd2 #pipe cmd1 stdout to cmd2's stdin cmd1 2>&1 | cmd2 #pipe cmd1 stdout and stderr to cmd2's stdin cmd1 | tee result.txt #print cmd1's stdout to screen and also write to result.txt cmd1 2>&1 | tee result.txt #print stdout,stderr to screen while writing to result.txt (or we could just make this a community wiki and enumerate such things here) Thanks!

  • android : how to run a shell command from within code

    - by ee3509
    I am trying to execute a command from within my code, the command is "echo 125 /sys/devices/platform/flashlight.0/leds/flashlight/brightness" and I can run it without problems from adb shell I am using Runtime class to execute it : Runtime.getRuntime().exec("echo 125 > /sys/devices/platform/flashlight.0/leds/flashlight/brightness"); However I get a permissions error since I am not supposed to access the sys directory. I have also tried to place the command in a String[] just in case spaces caused a problem but it didn't make much differense. Does anyone know any workaround for this ?

  • How to stop java application using a shell script

    - by Fernando Moyano
    I have a shell script, which is run under a opensuse linux, that starts a java application (under a jar), the script is: #!/bin/sh #export JAVA_HOME=/usr/local/java #PATH=/usr/local/java/bin:${PATH} #---------------------------------# # dynamically build the classpath # #---------------------------------# THE_CLASSPATH= for i in `ls ./lib/*.jar` do THE_CLASSPATH=${THE_CLASSPATH}:${i} done #---------------------------# # run the application # #---------------------------# java -server -Xms512M -Xmx1G -cp ".:${THE_CLASSPATH}" com.package.MyApp > myApp.out 2>&0 & This script is working fine. Now, what I want, is to write a script to kill gracefully this app, something that allows me to kill it with the -15 argument from Linux kill command. The problem, is that there will be many java applications running on this server, so I need to specifically kill this one. Any help? Thanks in advance, Fernando

  • get a list of function names in a shell script

    - by n-alexander
    I have a Bourne Shell script that has several functions in it, and allows to be called in the following way: my.sh <func_name> <param1> <param2> Inside func_name() will be called with param1 and param2. I want to create a "help" function that would just list all available functions, even without parameters. The question: how do I get a list of all function names in a script from inside the script? I'd like to avoid having to parse it and look for function patterns. Too easy to get wrong. Thanks, Alex

  • Optimize grep, awk and sed shell stuff

Any suggestion for optimizing this command? Regards Rene

  • Recursive FTP directory listing in shell/bash with a single session (using cURL or ftp)

    - by Timo
    I am writing a little shellscript that needs to go through all folders and files on an ftp server (recursively). So far everything works fine using cURL - but it's pretty slow, becuase cURL starts a new session for every command. So for 500 directories, cURL preforms 500 logins. Does anybody know, whether I can stay logged in using cURL (this would be my favourite solution) or how I can use ftp with only one session in a shell script? I know how to execute a set of ftp commands and retrieve the response, but for the recursive listing, it has to be a little more dynamic... Thanks for your help!

  • Executing shell commands from Java

    - by Lauren?iu Dascalu
    Hello, I'm trying to execute a shell command from a java application, on the GNU/Linux platform. The problem is that the script, that calls another java application, never ends, although it runs successfully from bash. I tried to debug it: (gdb) bt #0 0xb773d422 in __kernel_vsyscall () #1 0xb7709b5d in pthread_join (threadid=3063909232, thread_return=0xbf9cb678) at pthread_join.c:89 #2 0x0804dd78 in ContinueInNewThread () #3 0x080497f6 in main () I tried with: ProcessBuilder(); and Runtime.getRuntime().exec(cmd); Looks like it waits for something to finish. Any ideas? Thanks, Lauren?iu

  • Show last command with up arrow on a linux c shell

    - by nunos
    I have implemented a simple linux shell in c. Now, I am adding some features and one I immediately thought about was to be able to show the last commands with the up arrow. Question 1: However, I have no idea how to accomplish this. Do you? Question 2: Any comment on how to store the "history" commands are also appreciated. I suppose something like a queue which allows access to all elements would be a good idea. Am I wrong? Do I have to implement it or is there already some good implementation out there I should know about? Thanks.

  • Setting variables in shell script by running commands

  • Best way to choose a random file from a directory in a shell script

    - by jhs
    What is the best way to choose a random file from a directory in a shell script? Here is my solution in Bash but I would be very interested for a more portable (non-GNU) version for use on Unix proper. dir='some/directory' file=`/bin/ls -1 "$dir" | sort --random-sort | head -1` path=`readlink --canonicalize "$dir/$file"` # Converts to full path echo "The randomly-selected file is: $path" Anybody have any other ideas? Edit: lhunath makes a good point about parsing ls. I guess it comes down to whether you want to be portable or not. If you have the GNU findutils and coreutils then you can do: find "$dir" -maxdepth 1 -mindepth 1 -type f -print0 \ | sort --zero-terminated --random-sort \ | sed 's/\d000.*//g/' Whew, that was fun! Also it matches my question better since I said "random file". Honsetly though, these days it's hard to imagine a Unix system deployed out there having GNU installed but not Perl 5.

  • Shell script not picking up password file...

  • Shell Script - comparing lines of text, deleting matches

    - by SirRatty
    Hi all, I've done some searching for this but cannot find what I'm after, specifically. I have two files: "a.txt", "b.txt". Each contains a list of email addresses, separated by newlines. For all lines in "a.txt", I need to check for a match anywhere in "b.txt". If so, the email address in "a.txt" needs to be removed. (Alternatively, a new file "c.txt" could be created with the output if that is easier.) I'm using Mac OS X, so am looking for a shell script that could help, or pointers to how I'd go about constructing the script. Thanks for any help.
