I have a bash+expect script which has to connect via ssh to the remote comp, read the file there, find specific line with the "hostname" (like "hostname aaaa1111") and store this hostname into the variable to be used after while. How can i get the value of the "hostname" parameter? I thought that line content will be in $expect_out(buffer) variable (so i can scan it and analyze), but it's not. My script is:
#!/bin/bash ----bash part---- /usr/bin/expect << ENDOFEXPECT spawn bash -c "ssh root@$IP" expect "password:" send "xxxx\r" expect ":~#" send "cat /etc/rc.d/rc.local |grep hostname \n" expect ":~#" set line $expect_out(buffer) puts "line = $line, expect_out(buffer) = $expect_out(buffer)" ...more script... ENDOFEXPECT
Here http://en.wikipedia.org/wiki/Expect there is an example:
# Send the prebuilt command, and then wait for another shell prompt. send "$my_command\r" expect "%" # Capture the results of the command into a variable. This can be displayed, or written to disk. set results $expect_out(buffer)
seems that it doesn't work in this case, or what's wrong with the script?
