argv0(1)		    General Commands Manual		      argv0(1)

NAME
       argv0 - runs a program with a specified 0th argument.

SYNOPSIS
       argv0 realname zero args

DESCRIPTION
       realname	is one argument.  zero is one argument.	 args is any number of
       arguments.

       argv0 runs the program stored as	realname on disk, with zero as the 0th
       argument	(rather	than realname) and args	as the remaining arguments.

APPLICATIONS
       Some  programs  pay special attention to	the 0th	argument.  argv0 makes
       these programs usable from shell	scripts.

       For example,

	      argv0 /bin/csh -csh

       runs /bin/csh with a 0th	argument of -csh. /bin/csh will	think it is  a
       login shell and behave accordingly.

       As another example, the command

	      tcpserver	0 ftp argv0 tcpd ftpd -l -A

       has a similar effect to the line

	      ftp stream tcp nowait root tcpd ftpd -l -A

       in  /etc/inetd.conf. The	tcpd program is	run with 0th argument ftpd and
       remaining arguments -l -A. Note that tcpd can and should	be replaced by
       the -x option of	tcpserver(1):

	      tcpserver	-x ftp.tcp 0 ftp ftpd -l -A
