NAME
which — locate a program file including aliases and paths
DESCRIPTION
For each
name
given,
which
searches for the file that would be executed if
name
were given as a command, and displays the absolute path of that file.
Each argument is expanded if it is aliased,
and searched for along the user's path.
Both aliases and path are determined by sourcing (executing) the user's
.cshrc
file.
DIAGNOSTICS
A diagnostic is given for names
that are aliased to more than a single word,
or if an executable file with the argument name
was not found in the path.
EXAMPLES
The command:
specifies where the executable program of the
sh(1)
command is found.
For example, the response might be:
if the
sh(1)
being used is located in
/usr/bin.
WARNINGS
which
reports
.cshrc
aliases even when not invoked from
csh.
which
cannot find
csh
built-in commands (e.g., jobs).
which's
information may be incorrect because
it is unaware of any path or alias changes
that have occurred in the current shell session.
