Summary:
I am writing a script to check if a directory exists on a remote machine. I need a solution which can allow me to check for that directory and return the result in a usable way. This whole process is automated within a much larger script so I need a functional way to tell the parent script the directory exists or not.
Restrictions:
The tools that I have are limited. $REMOTE_2 can only be accessed through $REMOTE_1. Also, $REMOTE_2 can only be connected via telnet (no ssh available).
Current goal:
I am trying to set a local variable to be then read back to chose a return code. I am open to other options, but this is the closest I've come to a working solution so far.
I realize that $found will take from the parent process, but this is not my desired result and am not sure what syntax I need to return true or false when trying to echo the $found variable.
/usr/bin/expect<<EOF
spawn ssh $USER@$REMOTE_1
expect "*$USER*"
send -- "telnet $REMOTE_2\r"
expect "*login:*"
send -- "root\r"
expect "*$*"
# Everything prior to this can't be changed. Everything after it can be.
send "if \[ -d $DIRECTORY_LOCATION \] ; then found=true; else found=false ; fi\r"
send -- "echo **$found**\r"
expect {
"*true*" {
exit 0
}
"*false*" {
exit 1
}
}
EOF
I believe this type of solution can work, but I am not sure how to use the remote variable that I store within the if statement, later on to allow me to choose which return code to use.
