NAME

which − locate a command; display its pathname or alias

SYNOPSIS

which [ filename ] ...

DESCRIPTION

which takes a list of names and looks for the files which would be executed had these names been given as commands.  Each argument is expanded if it is aliased, and searched for along the user’s path.  Both aliases and path are taken from the user’s .cshrc file. 

FILES

~/.cshrc source of aliases and path values

SEE ALSO

csh(1)

DIAGNOSTICS

A diagnostic is given for names which are aliased to more than a single word, or if an executable file with the argument name was not found in the path. 

BUGS

Only aliases and paths from ~/.cshrc are used; importing from the current environment is not attempted.  Must be executed by csh(1), since only csh knows about aliases. 

To compensate for ~/.cshrc files in which aliases depend upon the prompt variable being set, which sets this variable.  If the ~/.cshrc produces output or prompts for input when prompt is set, which may produce some strange results.
