which.debianutils: locate a command

NAME

DESCRIPTION

which returns the pathnames of the files (or links) which would be executed in the current environment, had its arguments been given as commands in a strictly POSIX-conformant shell.

EXIT STATUS

0

if all specified commands are found and executable

1

if one or more specified commands is nonexistent or not executable

2

if an invalid option is specified
