Okay the issue was with expect. The weird thing is I tried break before and=
 it froze so I assumed it was not the issue. After restarting the terminal =
break worked:

            "Are you sure you want to continue connecting (yes/no)?" {exp_s=
end "yes\r"}

            "*assword:" { send "$unixpass\r"; }

Needs to be:

            "Are you sure you want to continue connecting (yes/no)?" {exp_s=
end "yes\r"}

            "*assword:" { send "$unixpass\r"; break }

If hung on password so I had to restart my terminal. Weird.

Subject: Issues with terminal freezing after scp in expect script.

Hi,

=20

I have interesting problem. I have bash script that calls an expect script =
that works fine and does an scp. However after the scp the terminal freezes=
. It is stuck on the bash prompt, however the prompt is not the original pr=
ompt. After I do ctrl C it continues to process. I tried to do a ctrl c/bre=
ak/exit in the expect script, but it does not work. Any ideas what could be=
 causing the problem? Scripts are below:

=20

Bash script:

=20

#!/usr/bin/bash

=20

echo `date`  " - Starting shell script."

=20

touch /apps/sjsws/sunws-automation/https-autodemo.cibcwm.com/docs/runshell

=20

echo `date` " - Copy files."

=20

expect /apps/sjsws/sunws-automation/https-autodemo.cibcwm.com/docs/SMWeblog=
ic/SMWeblogiccp.exp $1 $2 $5 $6

=20

file=3D`basename $1`

=20

echo `date` " - Run build on: " $file

# expect /apps/sjsws/sunws-automation/https-autodemo.cibcwm.com/docs/SMWebl=
ogic/SMWeblogicrun.exp $1 $2 $5 $6 $3 $4

=20

echo `date`  " - Finished."

=20

=20

Expect script:

=20

#!/usr/local/bin/expect -f

#

set filename [lindex $argv 0]

set hostname [lindex $argv 1]

set uu [lindex $argv 2]

set unixpass [lindex $argv 3]

=20

set force_conservative 0  ;# set to 1 to force conservative mode even if

                                      ;# script wasn't run conservatively o=
riginally

if {$force_conservative} {

            set send_slow {1 .1}

            proc send {ignore arg} {

                        sleep .1

                        exp_send -s -- $arg

            }

}

=20

=20

set timeout -1

spawn $env(SHELL)

match_max 100000

send -- "scp $filename $uu@$hostname:/tmp/\r"

while {1} {

        expect {

            "Are you sure you want to continue connecting (yes/no)?" {exp_s=
end "yes\r"}

            "*assword:" { send "$unixpass\r"; }

        }

    }

exp_send -- "=20

send -- "exit\r"

sleep 10

# send -- "scp /apps/sjsws/sunws-acs/https-acsdemo.cibcwm.com/docs/archives=
/smasa-12.zip $uu@$hostname:/tmp/\r"

while {1} {

        expect {

            "Are you sure you want to continue connecting (yes/no)?" {exp_s=
end "yes\r"}

            "*assword:" { send "$unixpass\r"; }

        }

    }

sleep 30

send -- "exit\r"

expect eof

Thanks,
