Perl script run a bash script
Hi All,
I think the processing of this is much more complex, so I will explain the whole process by codes.
First,I wrote a expect script named bsim.exp as follows:
Code:
#! /usr/local/bin/expect

set command [ lindex $argv 0 ]
set name [lindex $argv 1]
eval spawn $command

switch -exact $command {
    "bash expecttest.sh" {
        expect "Enter you name:*"
        send "$name\r"
        interact
    }
}

catch "wait -i $spawn_id" reason

# return status code of spawned process
exit [ lindex $reason 3 ]

And a bash script named expecttest.sh who wants to get a input

Code:
#!/bin/bash -x

echo "Enter you name: "
read name


if [ $name == "damon" ];then
    echo "Hi,Damon!"
else
    echo "Oop! you are not my host!"
fi

and I will use a bash script to run all the scripts
Code:
#!/bin/bash -x

./bsim.exp 'bash expecttest.sh' damon
print "test finish.\n";

Now if you run the script upper like this
Code:
bash-3.00# ./test.sh
+ ./bsim.exp 'bash expecttest.sh' damon
spawn bash expecttest.sh
Enter you name:
damon
Hi,Damon!

Now i want to use a perl file to run the test.sh and get the output and print on the screen.
Code:
#!/usr/bin/perl

@lines=`test.sh`

foreach (@lines){
    print $_."\n";
}

there always has some errors or no response.
I don't know what's the probelm of that.

Thanks and Best Regards
Damon

uudemon.cleanu

uudemon(4)						     Kernel Interfaces Manual							uudemon(4)

NAME

       uudemon.admin,  uudemon.cleanu,	uudemon.hour,  uudemon.poll  -	Administrative shell scripts for polling remote systems, cleaning up spool
       directories, reporting status to the system administrator, and routine invocations of the uuxqt and uusched daemons

SYNOPSIS

       These shell scripts reside in the following directory:
	  /usr/lib/uucp

DESCRIPTION

       All the scripts can be run from the command line or can be run automatically by the cron daemon. To automatically run the  scripts,  remove
       the comment character (#) from the beginning of the relevant line in the /var/spool/cron/crontabs/uucp file.

       This  script  reports  status  to  the system administrator. It issues the uustat command to find out the status of uucp jobs. It mails the
       results to the uucp login ID. The script may be modified to send mail to any login ID such as the uucp administrative login ID  (uucpa)	or
       root.  This script cleans up the /var/spool/uucp and /var/spool/uucppublic directories by running the uucleanup command. The uucleanup com-
       mand is run with the following parameters: -C7, -D7, X2, -o2, -W1.  This script runs the uusched and uuxqt daemons in the background.  This
       script  polls  the  systems  listed  in	the  /usr/lib/uucp/Poll file.  The uudemon.poll script should be scheduled before the uudemon.hour
       script. This allows uudemon.poll to create any command files before cron runs the uudemon.hour script.

FILES

       Contains the uudemon.admin, uudemon.cleanu, uudemon.hour and uudemon.poll files.  Contains the uucp file.

RELATED INFORMATION

       Commands: cron(8), uucleanup(8), uusched(8), uuxqt(1)

       Files: /usr/lib/uucp delim off
