Shell
Aliases
Aliases = Command Shortcuts
The alias shell command allows to define abbreviations for long commands.
If you use a particular command option combination frequently, introducing an alias for it will save a lot of typing, for example:
- alias ll ‘ls -alhF’
- alias cp ‘\cp -i’
- alias less ‘\less -MQige’
- alias RM ‘\rm -rf’
The above is the syntax for tcsh, for bash it is the following:
alias ll=‘ls -alhF’
If you wish to make those aliases permanent, you need to put them into the tcsh resource file ~/.tcshrc or the bash resource file ~/.bashrc .
