good examples of bash scripts

sigint-ninja · 03-31-2015, 04:24 PM

hi guys,

i know what bash scripts are
how to make them
and how to run them...

i have written some basic scripts that
show what users are logged on
how much free disk space there is etc
backup folders with rsync
also made a menu that let me select which host i wanted
to rdp into.

could somebody post here or point to a web site that has good examples of well used bash scripts on a production server...to see what / or try to see what exactly is going on...

would really appreciate any help

You can typically found tons of reasonably well-written scripts on your own system...

Try e.g. (as root)

Code:

grep -lr '#!/bin/sh' /etc

to find shell scripts
and

Code:

grep -lr '#!/bin/bash' /etc

to find bash scripts.

Instead of etc other directories (e.g. usr) also make sense. It obviously depends a bit on your distro

http://bashscripts.org/forum/
also grab a copy of the advanced bash scripting guide, it may be in your distros repo if not google it

check out this link:

http://mywiki.wooledge.org/FullBashGuide

or just trawl the web like searching Google "Bash Beginners Guide"

My $0.02 in BASH are in my signature links, the last line of it actually. One is a blog entry with some samples but really debug suggestions for general BASH programming. Also are links for the BASH guides.

You can just Google for "sample BASH scripts" and even be specific like "BASH script find files example" stuff like that.

The link provided by Keith Hedger is very good.

And also if you check out the LQ forums, specifically the Software and Programming forums you'll find a lot of BASH script questions with very helpful answers.

A few things to learn in addition to just scripting would be:

Regular Expressions
awk or gawk
sed

Good resources to use as examples are those with UNIX-centric solutions that solve low-level problems. Please see linux-shell-base as it was created for such solutions. Here is a list of some of the scripts it contains:

Run a command in the background (module).
Get the ID a window by name, class, PID, etc.
Get the ID, name, class, PID, etc. of the active window.
Return a file for a command by locating or recursively searching for it (module).
Check if a WLAN device is soft blocked.
Run a command in the terminal from outside of it (keybind utility).
Run a countdown timer in the terminal.
Bash utility functions (array, string, http, etc.).
Get contact info from an Android device.
Send an sms using an Android device.

@ajb57 welcome to LQ.

Stop resurrecting very old questions and posting your same information and link.

If you wish to self-promote some code you may do so with a single new thread.
