Creating Command Alias?

carlosinfl · 07-14-2007, 03:20 PM

I would like to create a simple alias for vpnc to just be vpn. Yes, I know the alias is simply the exclusion of one simple letter or key stroke but it is just a test as I have never done this before.

I did a search and there seems to be no man page on this on my system which led me to Google results and they did not work on my system.

Code:

tunafish:/home/cwilliams/Desktop# alias -p vpnc=vpn
alias cp='cp -i'
alias l='ls $LS_OPTIONS -lA'
alias ll='ls $LS_OPTIONS -l'
alias ls='ls $LS_OPTIONS'
alias mv='mv -i'
alias rm='rm -i'

What am I doing wrong?

Where did you get the "-p" switch?

On my machine, this works:

alias l=ls

And there is also "unalias"

Also no man page for either--I did get some info by typing "alias --help" and "unalias --help"

Code:

root@1[play]# alias --help
bash: alias: --: invalid option
alias: usage: alias [-p] [name[=value] ... ]
root@1[play]# unalias --help
bash: unalias: --: invalid option
unalias: usage: unalias [-a] name [name ...]
root@1[play]#

Still don't know what the switches do, but I'm guessing that "unalias -a" means delete all aliases. (I'm not going to try it--too lazy to recreate them all)

man bash
/^ *alias

Yes - unalias -a removes everything listed when you run the command "alias". I just tested it however I had some generic ssh and ls aliases I simply created on the fly.

Thanks all!
