Examples of .bashrc files

[Dec 9, 2007] Cool Solutions Bash - Making use of your .bashrc file

Too big but some ideas probably can be borrowed...

Details

I was playing with my .bashrc file again, and was once again impressed by how you can tweak Linux to do what YOU want it to do so easily. I am sure there are tons of other tweaks you can do to your .bashrc file, but I really like some of mine, and thought I would share them. Some of the alias's I created, some I found on the net, and some things in my .bashrc file are just there for fun, like the "# WELCOME SCREEN", although it does serve a purpose for me at the same time, it might not be something everyone would want or need.

For those that don't know what a .bashrc file does: "The ~/.bashrc file determines the behavior of interactive shells." Quoted From: The Advanced Bash Scripting Guide 

Basically , it allows you to create shortcuts (alias's) and interactive programs (functions) that run on the startup of the bash shell or that are used when running an interactive shell. For example, it's much easier to just type: ebrc instead of pico ~/.bashrc (I used the alias ebrc , and it stands for "Edit Bash RC file". I could have also aliased it to just use one letter, making it a VERY fast short cut. The bashrc file allows you to create alias's (shortcuts) to almost anything you want. My list is pretty long, but I'm sure there is someone with a longer list ;)

I have my .bashrc file setup in sections. The following is the breakdown by section of how I keep my list of alias's and functions separated. This is just how I do this, your .bashrc file can be modified to suit YOUR needs, that's the interesting part about the .bashrc file. It's VERY customizable and very easy to change.

Header (So I know when i modified it last and what i was running it on)
Exports (So I can set history size, paths , editors, define colors, etc,)
Sourced Alias's (So I can find those hidden alias's faster)
Workstation Alias's (so i can ssh to local machines quickly)
Remote Server Alias's (so i can ssh to remote servers easily)
Script Alias's (quick links to some of my bashscripts)
Hardware control alias's (so I can control cd/dvd/scanners/audio/etc)
Modified commands (Alias's to normal linux commands with special flags)
Chmod Alias's (makes changing permissions faster)
Alias's for GUI programs (start firefox, etc from command line)
Alias's for xterm and others (open xterm with special settings)
Alias's for Lynx (open lynx with urls - kind of a bash bookmark ;) )
UNused Alias's (Alias's that aren't in use on the system, but that i might use later)
Special functions (more of a function than just an alias..it goes here)
Notes (that should be self explanatory ;) )
Welcome Screen (code to make my bash shell display some stuff as it starts up)

That's how I lay out my .bashrc files. It may not be perfect, but it works well for me. I like making changes in just my .bashrc file and not the global files. I like the .bashrc file because you don't need root permissions to make changes that make your life easier at the bash shell.

The following is my .bashrc file (with some things obviously commented out for security... but most of it should be self explanatory). Anyone with comments/suggestions/ideas feel free to let me know. I'm always looking for new and interesting things to do with the .bashrc file.

Want to know what alias's your bash shell has? Simply type the word alias at the command line. The shell will then print out the list of active alias's to the standard output (normally your screen).

Useable as seperate programs, I've integrated them simply as functions for my .bashrc file in order to make them quick to use and easy to modify and find. These are functions that are used to symetrically encrypt and to decrypt files and messages. Some are completely command line, and the last two create gui interfaces to locate the files to encrypt/decrypt. If you create a program out of the functions creating a link via a shortcut/icon on the desktop would create a completely gui based interface to locate and encrypt/decrypt files. Either way, it's an easy way to use gpg.

echo ""; echo ""The following belong under the "function" section in my .bashrc. Useable as seperate programs, I've integrated them simply as functions for my .bashrc file in order to make them quick to use and easy to modify and find. These are functions that are used to symetrically encrypt and to decrypt files and messages. Some are completely command line, and the last two create gui interfaces to locate the files to encrypt/decrypt. If you create a program out of the functions creating a link via a shortcut/icon on the desktop would create a completely gui based interface to locate and encrypt/decrypt files. Either way, it's an easy way to use gpg.
