The alias command is used to create aliases, and to get a list of aliased commands.
Aliases creation
The syntax if shell dependant:
B-Shell (sh, bash) and Z-Shell (zsh) :
alias l=ls alias la='ls -A'
alias l ls alias la 'ls -A'
Special functions
Some shells provides additionnal features, such as the -g argument of zsh's alias built-in command. This allow creation of global aliases :
> alias a=aaa > alias -g b=bbb > echo a b a bbb
This can be very useful :
> alias -g ...='../..' > pwd /foo/bar/misc > cd ... > pwd /foo
For more informations on the specific options of your shell, have a look to it's man page.
Aliases consultation
You can use this to get an existing aliases list:
> alias ...=../.. ....=../../.. .....=../../../.. ......=../../../../.. .......=../../../../../.. clean='rm -f `find . -name "*~" -o -name ".*~" -o -name ".*.core" -o -name "*.core" -o -name "#*#" -o -name "a.out"` close='cdcontrol -f /dev/cd0 close' eject='cdcontrol -f /dev/cd0 eject' fr='export LANG=fr_FR.ISO8859-15' la='ls -a' ll='ls -Al' ls='ls -FG' > alias ls ls='ls -FG'
