[TriLUG] Single line scripts

[Aaron Morrison via TriLUG]

Don't forget shell aliases (and in some cases functions)

I have some dozen or so aliases to do some menial jobs that are not complicated enough for a script but very tedious to type every time. I keep them in my .bashrc file that I have in source control and push to every server I have an account for. I also make use of environment variables for some of them to be more generic and flexible.  It's simple and I only have to maintain one file. 

For a similar example, I have an alias named "rdp" that calls xfreerdp/rdesktop with all of the needed parameters and pass any arguments to the aliased command (such as a hostname)
