This script helps a user or admin to automatically convert items in fstab so that they would use UUIDs instead.

uuidfstab[.sh]
Code:
#!/bin/bash

function error {
	echo "$1" >&2
	exit 1
}

function show_usage_and_exit {

Pseudo-template noob hack that may apply for several situations

Posted 04-12-2012 at 04:10 PM by the dsc (linux-related notes)
Updated 04-12-2012 at 04:14 PM by the dsc

There's a painting software, "mypaint", which is very nice, but it does not support templates, at least not yet.

I've created a template (just a "blank" file with the correct resolution and whatnot) on GIMP, saved it as "ora", but instead of opening this file manually every time, and remembering to save it with a new name in order to not overwrite the template, I came up with a script that will create a new name automatically, with no risk of overwriting...

Bash functions to list and kill or send signals to process trees

Posted 03-31-2012 at 11:54 PM by konsolebox

These functions can be used in scripts or interactive shells to manipulate process trees. At least bash version 3.0 is needed. May also work with some earlier versions.

kill_tree - Creates a list of processes based from a parent process ID first then sends the signal to all of them synchronously.

kill_tree_2 - Same as killtree but it doesn't create a list first. It immediately kills processes as it goes through every level.

kill_tree_3 - This version...

Comment a block in shell

Posted 08-31-2011 at 12:22 AM by hi2arun
Tags bash, script

We all know, to comment out a line in shell script, '#' token is inserted in the line that needs to be made dead.
Eg:

Code:
# This is a dead line
echo "This line is live"
However, '#' token can be pesky if a block of lines need to be commented out.
Say, to comment out the following block using '#'

Code:
# comment starts here
# All these lines
# are blocked
# using '#' token
# ...
# ...

This post is a compilation of the function getabspath() for different shells that can be used to get the absolute form of a path. The function accepts an argument path then returns the absolute form of it to the variable $__.

bash (3.0 and newer only)
Code:
function getabspath {
	local -a T1 T2
	local -i I=0
	local IFS=/ A

	case "$1" in
	/*)
		read -r -a T1 <<< "$1"
		;;
	*)
		read
