Top Forums Shell Programming and Scripting How to use 'expect' to pass UID & Password to a "for loop" in shell script? Post 302874141 by thisissouvik on Thursday 14th of November 2013 09:08:10 AM

Friend's,

I expected a response from one of you today, but none Smilie

I could manage to get my requirement by adding echo.out.$h in the scp portion of the script & not in the set cmd section as below:

Code:
cat expect_script.sh
#!/usr/bin/expect -f
#
#

# set credentials
set u "msouvik"
set p "pass^123"

# get host name from command-line
set h [lindex $argv 0]

# set the command to run
set cmd "echo Hello Buddy! >> /export/home/msouvik/echo.out"

# spawn a connection to the host and run the given command
spawn -noecho ssh -t $u@$h $cmd

# handle the password prompt for ssh
expect "Password:*"
send -- "$p\r"
send -- "\r"

# scp the data onto NIM server
spawn -noecho scp $u@$h:/export/home/msouvik/echo.out /export/home/msouvik/echo.out.$h

# handle the password prompt for scp
expect "Password:*"
send -- "$p\r"
send -- "\r"

# done
expect eof

However, this modification is creating a new problem - now the portion of code(highlighted in red) isn't working, it simply doesn't write to the file on the destination server. I've pasted the above code as it is from the server.

I'm not able to catch what happened to the working code with this small modification, could one you guys help me here? Excuse me (if) I'm forcing you guys to help Smilie
