Example script to run and manage a service (tcpdump) with managed logging.

I made this script as a reply to a question on a thread before. The accidentally simplified complexity of it amazes me so I thought that it would be nice to post this on a blog as well. Original thread: https://www.linuxquestions.org/quest...cpdump-800385/

The script runs and manages a service (tcpdump). It could also automatically delete files older than C days, and reduce the size of a logfile if it's already larger than N bytes....

I made this utility along with binfind. It also has had lots of improvements since then.

This script can be used to search files contained in library files (*.so, *.la, *.a, etc.) based from keywords provided. Along with a custom list of default paths, it will search for libraries inside directories that are specified in /etc/ld.so.conf. It would also examine files that are specified by the "include" directive in it.

After preparations it would search for...

binfind - Search for executable files based from PATH variable.

Tags bash, script

I've been using this utility quite long enough already. I use this to search for executable files based from the path values saved in the PATH variable.

Code:
#!/bin/bash

shopt -s extglob

function main {
	# check bash version

	[[ BASH_VERSINFO -ge 3 ]] || {
		echo "This script requires bash version 3.0 or newer."
		return 1
	}

	# check arguments

	[[ $# -eq 0 || "$1"

uuidfstab - Convert fstab contents to a format that uses UUID instead of /dev paths.

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 {
	error "Usage: $0 <path_to_fstab_file> [<new_fstab_file>]"
}

function process {
	local FSTABFILE=$1 NEWFSTABFILE=$2 LINE DEVICE TEMPFILE ID OUTPUTFILE

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

Posted 03-31-2012 at 11:54 PM by konsolebox
Updated 07-28-2014 at 11:39 AM 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.

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

killtree2 - Same as killtree but it doesn't create a list first. It immediately kills processes as it goes through every level.

killtree3 - This version kills...
