NAME

waitfor - wait for a string to appear on the stdin

SYNOPSIS

waitfor [ -n ] string

DESCRIPTION

Waitfor reads the standard input and returns a 0 if the string argument is found, returns a 1 if the strings did not appear within the allotted time, or returns a -1 on error. If the string is found, waitfor returns immediately.

Waitfor is designed to be used by Pcomm in a shell script for automatically logging a user onto a remote system.

The -n option is used to specify the length of time in seconds to wait. The default is 10 seconds.

EXAMPLE

        # wait 5 seconds for the login prompt
        waitfor -5 login:
        # test the exit code of the waitfor command
        if [ $? -eq 0 ]
        then
                # send my user ID
                echo egray
        fi
