which(1)which(1)NAMEwhich - Locates a program file including aliases and paths
SYNOPSISwhich program...
DESCRIPTION
The which command takes a list of program names and looks for the files
that would be executed if these names were given as commands.
Each program argument is expanded if it is aliased and searched for
along your path. Both the aliases and path are taken from your file.
If you do not have a file, the path is the current PATH from your envi‐
ronment.
The C shell includes a built in which command. The which command
described here (written in csh script language) is provided for shells
such as the Bourne shell that lack a built-in which command like the C
shell.
FILES
Read at beginning of execution by each shell.
DIAGNOSTICS
A diagnostic is given if an executable file with the argument name was
not found in the path.
