WHICH(1)                   OpenBSD Reference Manual                   WHICH(1)

     which - locate a program file (or files) in the path

     which [-a] name [...]

     which takes a list of names and looks for the files which would be exe-
     cuted had these names been given as commands.  Each argument is searched
     for along the user's path.

     If the -a flag is given, which will return a list of all matches instead
     of just the first match.

     The which utility exits with one of the following values:

     0     All names were successfully resolved.
     1     Some names were resolved but not all.
     2     No names were resolved.
     -1    A system error occurred.

     A diagnostic is given if an executable file with the argument name was
     not found in the path.

     PATH  which uses the environment variable PATH as a colon-separated list
           of directories in which to find executables.  If PATH is not set,
           and the given name is not a fully qualified or relative pathname,
           which will fail.

     The which command formerly was a csh(1) script and could expand aliases.
     csh(1) now has a built-in which command so this version is intended for
     use with other shells like sh(1).

     csh(1),  find(1),  locate(1),  sh(1),  whereis(1),  environ(7)

     A which command appeared in 3.0BSD.
