.TH WHICH 1
.SH NAME
which \- examine $PATH to see which file will be executed
.SH SYNOPSIS
\fBwhich \fIname\fR
.br
.de FL

.SH EXAMPLES

.B which a.out
# Tells which \fIa.out\fR will be executed
.SH DESCRIPTION
.PP
The $PATH shell variable controls the
\s-1MINIX 3\s-1
search rules.
If a command \fIa.out\fR is given, the shell first tries to find an
executable file in the working directory.
If that fails, it looks in various system directories, such as
\fI/bin\fR and \fI/usr/bin\fR.
The\fR which\fR command makes the same search and gives the absolute
path of the program that will be chosen, followed by other occurrences
of the file name along the path.
.SH "SEE ALSO"
.BR man (1).

.Sh NAME
.Nm whereis
.Nd locate programs
.Sh SYNOPSIS
.Nm
.Op Fl p
.Ar program
.Op Ar program ...
.Sh DESCRIPTION
The
.Nm
utility checks the standard binary directories for the specified programs,
printing out the paths of any it finds.
.Pp
The default path searched is the string returned by the
.Xr sysctl 8
utility for the
.Dq user.cs_path
string.
If the
.Op Fl p
option is specified, then the value of the environment
variable
.Ev PATH
is used instead.
.Sh EXIT STATUS
The
.Nm
utility exits 0 on success, 1 on general error, 2 if only some
programs were located and 3 if none were.
.Sh SEE ALSO
.Xr whatis 1 ,
.Xr which 1 ,
.Xr sysctl 8
.Sh COMPATIBILITY
The historic flags and arguments for the
.Nm
utility are no longer available in this version.
.Sh HISTORY
The
.Nm
command appeared in
.Bx 3.0 .

.Sh NAME
.Nm which
.Nd "locate a program file in the users $PATH environment variable"
.Sh SYNOPSIS
.Nm
.Op Fl a
.Ar name
.Op Ar ...
.Sh DESCRIPTION
.Nm
takes a list of names and looks for the files which would be
executed had these names been given as commands.
Each argument is searched for along the user's
.Ev PATH .
.Pp
If the
.Fl a
flag is given,
.Nm
will continue to search the
.Ev PATH
until all instances of a program file are found.
.Sh HISTORY
The
.Nm
command appeared in
.Bx 3.0 .
.Sh BUGS
This implementation does not expand
.Xr csh 1
aliases, and is shell agnostic.
This is really a feature.
