An alternative c-shell. It's also the default shell used by old systems at University of Calgary Computer Science.
Configuration
The .tcshrc file defines the tcsh configuration. An example file follows:
# User specific aliases and functions
alias rm 'rm -i'
alias cp 'cp -i'
alias mv 'mv -i'
set prompt = "%m:%~ %h# "
set histfile = ~/.tcsh_history
set autolist
bindkey "\e[1~" beginning-of-line # Home
bindkey "\e[7~" beginning-of-line # Home rxvt
bindkey "\e[2~" overwrite-mode # Ins
bindkey "\e[3~" delete-char # Delete
bindkey "\e[4~" end-of-line # End
bindkey "\e[8~" end-of-line # End rxvt
Issues
Tcsh has some annoyances out of the box which is 'fixed' with the changes made to .tcshrc above. Here are what the these changes are:
Auto Completion
The tab key will by default not do anything, unless the following line is in your tcshrc file:
set autolist
History Logging
Similar to the .bash_history file in bash, you can tell tcsh to log your commands in a file by adding the following to your .tcshrc file:
set histfile = ~/.tcsh_history
Remapping Home,End,Delete Keys in tcsh
Add the following to your .tcshrc file:
bindkey "\e[1~" beginning-of-line # Home
bindkey "\e[7~" beginning-of-line # Home rxvt
bindkey "\e[2~" overwrite-mode # Ins
bindkey "\e[3~" delete-char # Delete
bindkey "\e[4~" end-of-line # End
bindkey "\e[8~" end-of-line # End rxvt
