Linux : these script enable you to edit multiple files and remove exact phrase from multiple files

This will, for an application that has already been removed but had its configuration left behind, purge that configuration from the system. To test it out first, you can remove the last -y, and it will show you what it will purge without actually doing it. I mean it never hurts to check first, "just in case." ;)

Find and kill multiple instances of a process with one simple command.

it recursively searches your project's directories and sum the lines of every source [.c or .h]. Then it gives you the total.

Original submitter's command spawns a "grep" process for every file found. Mine spawns one grep with a long list of all matching files to search in. Learn xargs, everyone! It's a very powerful and always available tool.

When you do a ls -1 | xargs rm it wouldn't workd because those files have spaces. So you must use find -print0 and xargs -0

After this command you can review doit.sh file before executing it. If it looks good, execute: `. doit.sh`

Will search recursively and output the searchResult.txt in the same folder you are located.

Well this can come handy , when you don't feel like playing with pid rather if you know the process name say "firefox",it would kill it.The script given below would kill the process with its name given as first parameter , though not robust enough to notify that process doesn't exist , well if you know what you are doing that's wouldn't be a problem.:) ---- killhim.sh ---- #!/bin/bash ps -u $USER |grep $1 | awk '{ print $1}'| xargs kill ----

Did some research and found the previous command wrong, we don't kill a zombie but its parent. Just made some modifcation to khashmeshab's command.

Watches for file modifications in the current directory and tails the file.

xargs will automatically determine how namy args are too many and only pass a reasonable number of them at a time. In the example, 500,002 file names were split across 26 instantiations of the command "echo". Show Sample Output
