NAME

which - locate commands

SYNOPSIS

which command [ command ... ]

ARGUMENTS

command: Command or list of commands to locate.

DESCRIPTION

which checks, in order, a list of internal command-shell commands, the current directory, and directories specified in the user's PATH variable for the commands given as its arguments. If a given command is found, its full path is printed; otherwise a ``not found'' message is printed with a list of the directories which were checked. In the case the command is an internal shell command, a message to this effect is printed in lieu of a path.

which respects the shell precedence of command extensions; thus more.com is listed instead of more.exe, should both exist in the same directory. Likewise, .exe files have precedence over .cmd files, and .cmd files over .bat files. A command with a dot in its name has precedence over any default extension; for example, list.old is found before list.old.exe.

EXAMPLE

The following command lists the locations of four commands:

which dir format unzip zipinfo

dir: OS/2 command-shell internal command
c:\os2\format.com
c:\utils\32\unzip.exe
no zipinfo in . c:\os2 c:\utils\32 c:\utils\16 c:\utils\bnd
c:\os2\system c:\emx\bin c:\groff\bin c:\os2\mdos\winos2
c:\os2\install c:\ c:\os2\mdos c:\os2\apps c:\ibmtk\os2bin
c:\ibmwf\bin c:\ibmc\bin

BUGS

The list of internal shell commands is static and does not reflect differences between various versions, including third-party shells such as 4OS2 (or 4DOS).
