NAME

     which -- locate a program file in the user's path

SYNOPSIS

     which [-as] program ...

DESCRIPTION

     The which utility takes a list of command names and searches the path for each executable file that would be run had these commands actually
     been invoked.

     The following options are available:

     -a      List all instances of executables found (instead of just the first one of each).

     -s      No output, just return 0 if all of the executables are found, or 1 if some were not found.

     Some shells may provide a builtin which command which is similar or identical to this utility.  Consult the builtin(1) manual page.

SEE ALSO

     builtin(1), csh(1), find(1), locate(1), whereis(1)

HISTORY

     The which command first appeared in FreeBSD 2.1.

AUTHORS

     The which utility was originally written in Perl and was contributed by Wolfram Schneider <wosch@FreeBSD.org>.  The current version of which
     was rewritten in C by Daniel Papasian <dpapasia@andrew.cmu.edu>.

NOHUP(1)						    BSD General Commands Manual 						  NOHUP(1)

NAME

     nohup -- invoke a utility immune to hangups

SYNOPSIS

     nohup [--] utility [arguments]

DESCRIPTION

     The nohup utility invokes utility with its arguments and at this time sets the signal SIGHUP to be ignored.  If the standard output is a ter-
     minal, the standard output is appended to the file nohup.out in the current directory.  If standard error is a terminal, it is directed to
     the same place as the standard output.

     Some shells may provide a builtin nohup command which is similar or identical to this utility.  Consult the builtin(1) manual page.

ENVIRONMENT

     The following variables are utilized by nohup:

     HOME  If the output file nohup.out cannot be created in the current directory, the nohup utility uses the directory named by HOME to create
	   the file.

     PATH  Used to locate the requested utility if the name contains no '/' characters.

DIAGNOSTICS

     The nohup utility exits with one of the following values:

     126     The utility was found, but could not be invoked.

     127     The utility could not be found or an error occurred in nohup.

     Otherwise, the exit status of nohup will be that of utility.

SEE ALSO

     builtin(1), csh(1), signal(3)

STANDARDS

     The nohup utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.

BUGS

     Two or more instances of nohup can append to the same file, which makes for a confusing output.
