• Writting this Bash Script to accept Arguments?

  - by Urda

  How would I go about converting this bash script: mkdir /store/sftp/%USERNAME% sudo useradd -d /incoming %USERNAME% sudo passwd %USERNAME% ## Password needs to be typed or passed in here sudo usermod -g sftp %USERNAME% sudo usermod -s /bin/false %USERNAME% sudo chmod 755 /store/sftp/%USERNAME% sudo chown root:root /store/sftp/%USERNAME% sudo mkdir /store/sftp/%USERNAME%/incoming sudo chown %USERNAME%:sftp /store/sftp/%USERNAME%/incoming To accpet a username and a password?

• Formatting the BASH command prompt

  - by Robert S. Barnes

  I would like to change the formatting on my BASH prompt from this: [email protected]:~/some/very/annoying/long/path$ to something like this: [email protected]:~/some/very/annoying/long/path $ The idea is that I would be able to type a reasonably long command on one line without it wrapping to the next line so quickly.

• What's wrong with this bash prompt?

  - by takeshin

  I use the following entry in ~/.bashrc file to colorize the prompt and display current branch of git repository: PS1='\[\e[1;32m\]\[\u@\h\]\[\e[m\] \[\w\]\[\e[1;1m\]\[$(__git_ps1 " (%s)")\] \[\e[1;1m\]\[$\] \[\e[m\]' This works almost fine, except when I use bash history (up arrow key few times), the command line becomes 'outdented' (just the first characters of the prompt remains untouched), and the visible is: usemmand when my username is user and the command is command.

• MAC OSX Mavericks, using bash to see "Get Info" attributes

  - by Rell3oT

  I want to use my bash shell to see the attributes that are shown when you right click on an Application and click Get Info. The specific attributes that I want to know whether or not they are checked is Open in Low Resolution, Prevent App Nap, and Locked. I looked in the Info.plist file but only generic information about the file was contained here, not which attributes were checked. Is this information contained in the Applications binary? Where is it?

• Put a task to the background with bash

  - by zneak

  Hey guy, I know that you can start a background job with Bash doing foo &. However, the best way I know to put a foreground job to the background is to do Ctrl+z to pause it then bg 1 to resume it in the background. Is there a faster way? Some Ctrl+Something key combination I'm not aware of? Thanks!

  I'm using Putty Connection Manager which captures CTRL-R key before it can get to my bash shell. So I was wondering if it is possible to map the reverse-history-search to another shortcut key. Such as CTRL-W or maybe even F1. Any help would be appreciated.

• how to set multiple white spaces (ex: tabs) as delimiters in bash's `cut`

• send process straight to bg in bash

  - by ItsNannerpuss

  I find I frequently use the combination of Suspend (^Z) then send to background (bg) in bash. Ideally I would like an alternate keyboard shortcut that negates the need to follow ^Z with the bg command, and just send the active process straight to background. Does this exist? Edit: I should have been more specific, but appending & to the command is not sufficient, as they often require interaction (stdin) between launch and backgrounding. So: launch interact background

• Bash or Zsh - which one and why?

  - by Andrew

  So, the question pretty much says it all. I'm on Snow Leopard, and I do a lot of web development, particularly in Rails 3 which makes heavy use of the console. I've seen some notable bloggers etc. mention Zsh as their preference over Bash, but I don't know what difference it would make. Could anyone give me a good comparison of what difference there is and what might make one prefer one option or the other? Thanks!

• How to overwrite the data in a file with bash

  - by Stefan Liebenberg

  I'm writing a bash script that encrypts the data of a folder or file #!/bin/bash file_name=$1 tmp_file=/tmp/tmpfile.tar # tar compress file tar -cf $tmp_file $file_name; # encrypt file gpg -c $tmp_file # remove temp file rm -rf $tmp_file $file_name # mv encrypted file to orignal place mv ${tmp_file}.gpg $file_name but the data will still be recoverable by using photorec or similar methods... Is there a way to ensure the absolute deletion of the original file in bash? Thank You Stefan

• How to automatically add user account *and* password with a Bash script

  - by ModernCarpentry

  I need to have the ability to create user accounts on my Linux ( Fedora 10 ) and automatically assign a password via a bash script ( or otherwise, if need be ). It's easy to create the user via Bash eg: [whoever@server ]# /usr/sbin/useradd newuser But is it possible to assign a password in Bash, something functionally similar to this (but automated): [whoever@server ]# passwd newuser Changing password for user testpass. New UNIX password: Retype new UNIX password: passwd: all authentication tokens updated successfully. [whoever@server ]#

• bash script to check running process

  - by elasticsecurity

  I wrote a bash-script to check if a process is running. It doesn't work since the ps command always returns exit code 1. When I run the ps command from the command-line, the $? is correctly set, but within the script it is always 1. Any idea? #!/bin/bash SERVICE=$1 ps -a | grep -v grep | grep $1 > /dev/null result=$? echo "exit code: ${result}" if [ "${result}" -eq "0" ] ; then echo "`date`: $SERVICE service running, everything is fine" else echo "`date`: $SERVICE is not running" fi Bash version: GNU bash, version 3.2.25(1)-release (x86_64-redhat-linux-gnu)

• Quicker searching in JScript using the Bash

  - by gentlesea

  I am using the following JScript code to search for a string inside a file: var myFile = aqFile.OpenTextFile(fileToSearchIn, aqFile.faRead, aqFile.ctANSI); while(!myFile.IsEndOfFile()) { s = myFile.ReadLine(); if (aqString.Find(s, searchString) != -1) Log.Checkpoint(searchString + " found.", s); } myFile.Close(); This is rather slow. I was thinking about using bash commands in order to speed up the search in file process: var WshShell = new ActiveXObject("WScript.Shell"); var oExec = WshShell.Exec("C:\\cygwin\\bin\\bash.exe -c 'cat \"" + folderName + "/" + fileName + "\"'"); while (!oExec.StdOut.AtEndOfStream) Log.Checkpoint(oExec.StdOut.ReadLine()); while (!oExec.StdErr.AtEndOfStream) Log.Error(oExec.StdErr.ReadLine()); Since every time bash.exe is started a new window opens the searching is not faster than before. Is there a possibility to have the bash run in the background using another switch?

• Unable to modify git bash Windows shortcut

  - by netgirlk

  Under Windows 7 I'd like to change the settings for the Git Bash Here shell extension command window, e.g. width, height and font. But when I do this, I get an error "Unable to modify the shortcut". I can modify the shortcut for Git Bash in the Start menu by using "Run as administrator..." This works, but only for Bash windows opened from the Start menu. It doesn't work for the "Git Bash Here" shell extension and there's no "Run as administrator..." option on right-click context menu. How do you do it?

• Bash script to log in over SSH

  - by user1042928

  Sorry if this seems like a dumb question but I am just learning bash scripting. For a school project we need to code an RTX that runs in Unix. It runs as a process in terminal and takes in user input and then prints it to the screen. I want to write a bash script to test that it can respond to lots of quick user input without overflowing or failing. My main problem is that once the RTX starts the bash script will stop on that line until the RTX terminates and only then print the loop to the terminal (instead of printing it to the RTX prompt as I intend it to). I have tried running the RTX in the background but that didn't work. I need to find a way to redirect input to the RTX while it is still running with a bash script. Google searches didn't come up with examples that I understood/could adapt. Any help is appreciated. #!/bin/bash # declare STRING variable STRING="RTX Worked =D" #Start the rtx in a new process, stuck on this line until rtx terminates. ./main #Somehow redirect io to the rtx. for i in `seq 1 100`; do echo $i echo " \n" done echo $STRING
