argv0(1)               DragonFly 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
