TCL(Tool Command Language) Scripting :: interact difficulties


	interact difficulties I am writing a script to ssh into remote machines and run tripwire. I'd like it to go interactive at the point the editor (vi) fires up and to resume non-interactive mode once the file is saved. I have a working test script: #!/usr/bin/expect spawn /bin/bash expect "$" send "vi tt\r" interact { \003 return } send exit This allows me to edit the file tt and hit CTRL-C when finished. Here's the expect portion of the real script (it's run as a here document, so the variables are substituted in by /bin/sh): #!/usr/bin/expect spawn ssh -4p8889 ${addr[$a]} expect "$ " send -- "sudo /usr/sbin/tripwire --check -I\r" $pwd # deals with the sudo password interact { ! return } expect "Please enter your local passphrase:" { send "SANITIZED" } expect "\$ " send -- "exit" expect eof I've tried many different characters and nothing seems to work. Ideally, I'd like the script to discern when the edit is finished and return from interactive mode, but I had no luck with "interact -o" either.

Probably a glitch, but as it happens it doesn't matter anyway: % string equal "$" "\$" 1 Mark
