Quick example of spawning a problem that have a password prompt and can't accept a documented parameter for a password. I used another bash script to simulate a password prompt but in my automation challenge it was an executable that prompted.<\/p>\n
Main script just to take a password for passing to expect. Could also be hard coded.<\/p>\n
$ cat expect_example_main.sh
\n#!\/bin\/bash
\necho \"Enter the password: \"
\nread -s -e password
\n.\/expect_example.exp $password ;<\/p>\n
Here is the expect script that will be interacting with the real program with the password prompt.<\/p>\n
$ cat expect_example.exp
\n#!\/usr\/bin\/expect -f<\/p>\n
# Set variables
\nset password [lindex $argv 0]
\nset date [exec date +%F]<\/p>\n
# Log results
\nlog_file -a expect-$date.log<\/p>\n
# Announce device & time
\nsend_user \"\\n\"
\nsend_user \">>>>> Working @ [exec date] <<<<<\\n\"\nsend_user \"\\n\"\n\nspawn .\/expect_example_prompt.sh\nexpect \"*assword:\" {send \"$password\\r\"}\ninteract\n\nThis is the simulated executable with the prompt. Expect will be spawning this one.\n\n$ cat expect_example_prompt.sh \n#!\/bin\/bash\necho \"Enter the password: \"\nread -s -e pwd\nif [ $pwd == 'fool' ]; then\n echo \"password correct\"\nelse\n echo \"password NOT correct!\"\nfi\n\nShowing run time with correct password.\n\n$ .\/expect_example_main.sh \nEnter the password: \n\n>>>>> Working @ Thu Jan 19 14:54:00 CST 2017 <<<<<\n\nspawn .\/expect_example_prompt.sh\nEnter the password: \npassword correct\n\nShowing run time with incorrect password.\n\n$ .\/expect_example_main.sh \nEnter the password: \n\n>>>>> Working @ Thu Jan 19 14:54:28 CST 2017 <<<<<\n\nspawn .\/expect_example_prompt.sh\nEnter the password: \npassword NOT correct!\n\n<\/p>\n","protected":false},"excerpt":{"rendered":"
