Expect command use for interactive mode of scripting

Hi All,

I am writing a script(Auto_Installation.sh) which is calling one another script (./update_manager /spare/install/HO7/PME_Response_file.txt)

Now the issue is result of (./update_manager /spare/install/HO7/PME_Response_file.txt) script is

##########################################
OAM Update Manager - Main Menu
==============================

1. Install an OAM PME
2. Uninstall an OAM PME
3. View installed OAM PMEs
4. Exit the Update Manager
Choose an Option:
##########################################

NOw I want to give input as "1". so that script can move forward.
I tried expect command but I am failing every time

IN Auto_Installation.sh

./update_manager /spare/HO16/pme.response.template
expect "Choose an Option:"
send 1\r

o/p of this is

^Ccouldn't read file "Choose an Option:": no such file or directory
expect_example.sh: line 7: send: command not found

I am not sure how to utilize expect in this case.

Please help me.

Thanks,

Try this...

echo 1 | ./update_manager /spare/install/HO7/PME_Response_file.txt

If you have autoexpect installed, try that...

Hi Ahmed,

Thanks for reply. I could not follow that command because after pressing "1" I need to install certain PMEs and for that I need to give absolute path for those PMEs.

So, inshort I need to pass total 7 outputs inside ./update_manager /spare/install/HO7/PME_Response_file.txt script.

Then update manager script will be over.

That is why I am trying expect command.

Thanks,
Dhruvak

If there are so many inputs, why not have a configuration file and read the data from that...

How? Will you please give an example?

Will anyone please help me in this case?

:wall:

So, Finally I found a solution.

#!/usr/bin/expect
spawn -noecho /opt/opwv/oam/1.8/bin/update_manager /spare/HO16/pme.response.template
expect "Option:"
send 3\r
expect "detailed information:"
send 1\r
expect "continue:"
send \n\r

And call this script like
./expect_example.sh
