Tcsh Shell Script File Examples

This section provides some Tcsh script file examples.

The Tcsh shell supports executable script files, which are collections of Bash command lines stored in text files. When a script file is executed, all command lines in the script file will be executed in the same order they appear in the file.

Here is a Tcsh shell script file, f, which uses 3 command programs to print information about the specified file:

# f name
if ( $#argv == 0 ) then
   echo "Usage: f name"
if ( ! -e $1 ]) then
   echo "Error: File $1 does not exist"
echo ""
echo "File list info:"
ls -l $1 # list file info
echo ""
echo "Numer of lines:"
wc -1 $1 # count words in this file
echo ""
echo "File type:"
file $1

Tcsh shell supports startup run commands stored in the .tcshrc in the home directory. Here is a simple example of .tcshrc file:

set prompt="%S %m %/ %s%% "
set path = ( . /usr/local/bin /usr/bin /bin)
set history=50
set savehist
setenv MANPATH /usr/local/man:/usr/man
umask 022
limit coredumpsize 0
setenv EDITOR vi
setenv VISUAL vi
setenv PAGER more
