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
