Combined bash and expect script

Paul77 · 03-02-2007, 03:34 PM

Hi
can anyone inform if its possible to run an expect script followed by a bash
shell script from one script?

Sure, no problem:

Code:

#!/bin/bash
# Run an expect script
/usr/local/bin/someExpectScript
# Run a bash script
/usr/local/bin/someBashScript

Hi
thanks for the reply but won't there need to be
a #!/usr/bin/expect line somewhere in the file?

No. The expect script is '/usr/local/bin/someExpectScript' - that needs the '#!/usr/bin/expect' magic.

Hi

The following does not work - the log script completes but the setview does not.
If the setview is performed first then the log script is not run.

#!/bin/bash

#run login script
log

cleartool setview pblades__view

Please post both scripts (in code blocks) so we can see what is happening.

ok here is a cat of the expect script and the bash script that calls it and
the output when the bash script is run

pb@dhcp-172#
p@dhcp-172#
pb@dhcp-172#
pb@dhcp-172#
pb@dhcp-172# cat lg
#!/usr/bin/expect

spawn ssh pb@smokey

# pb@smokey's password:
expect "password:" {
send "aaaaaaaa\r"
}

interact

pb@dhcp-172#
pb@dhcp-172#
pb@dhcp-172#
pb@dhcp-172#
pb@dhcp-172#
pb@dhcp-172# cat log
#!/bin/bash

#run login script
/u/pb/scripts/lg

cleartool setview pb__merge_to_1.1

pb@dhcp-172#
pb@dhcp-172#
pb@dhcp-172#
pb@dhcp-172#
pb@dhcp-172# log
spawn ssh pb@smokey
pb@smokey's password:
Last login: Mon Mar 5 16:22:42 2007 from dhcp-172
setting DISPLAY=dhcp-172:0
Linux Startup

Hello

pb@smokey#
pb@smokey#
pb@smokey#

=> the login script lg completes but the next line to set the view
is not run

That's because of the 'interact'; the first script effectively never exits until the session ends.

Paul77 · 03-05-2007, 03:18 PM

If the setview is done first then the log script
should'nt both have worked?

What is setview?

If you are going to paste again, please use a code block. It's hard to see the delineation between comments and code above. In the advanced reply text box, select your code and click on the "#" icon (when you hover over the icons they identify their function).

The setview line: cleartool setview <view>
sets the current view to a given view.

If its the first line in the scripts then the
expect login script is not carried out.

If the setview line is replaced with a pwd
then the expect script is carried out.

Any ideas why this and if there is a way of getting
round the problem?

Code:

#!/usr/bin/expect

spawn ssh pb@smokey

# pb@smokey's password:
expect "password:" {
send "aaaaaaaa\r"
}

interact

Code:

#!/bin/bash

cleartool setview pb__merge_to_1.1

#run login script
/u/pb/scripts/lg

Without seeing the close for "cleartool" I can tell you why it's not returning control.
