How to return value from expect script?
Hi there.
There is a shell script:
Code:
#!/bin/bash 
ARGS=`(grep -i $1 old.txt || grep -i $1 new.txt) |awk 'BEGIN {FS=","}{print "\x27" $5 "\x27"}' | tr "\n" " "` 
/usr/bin/expect -- << EXPECTEND 
spawn -noecho myssh myhost.localnet 
log_user 0 
expect root 
log_user 1 
send "/home/one.pl $ARGS\r" 
set val $expect_out(buffer) 
send_user "$val" 
#expect eof 
EXPECTEND

This does not works.
When i commented out line before last, i saw required output, but script executed 10 secs longer, i guess "expect eof" force script to wait for some timeout. However $val is still empty, i just see output of send "/home/one.pl $ARGS\r"
Pls advise how to pass variable from expect to bash without waiting?

I'm not familiar with myssh, but if it works like ssh, something like this may work:

Code:
val=$(
  myssh root@myhost.localnet "/home/one.pl $ARGS"
  )

What I mean is I'm not sure if you need expect in this case.

Could it be a bash script ?
OK, if you really need to use expect, you may try something like this:

Code:
/usr/bin/expect -- << EXPECTEND 
spawn -noecho myssh myhost.localnet 
log_user 0 
expect root
expect "your_exact_prompt_string_here_including_the_trailing_space" 
log_user 1 
send "/home/one.pl $ARGS\r" 
expect "your_exact_prompt_string_here_including_the_trailing_space" 
send "logout\r"
EXPECTEND

try like this
Code:
#!/bin/bash
ARGS=`(grep -i $1 old.txt || grep -i $1 new.txt) |awk 'BEGIN {FS=","}{print "\x27" $5 "\x27"}' | tr "\n" " "`
PASSWD="$(/home/one.pl $ARGS)"
VAL=$(/usr/bin/expect -- << EXPECTEND
spawn -noecho myssh myhost.localnet
log_user 0
expect root
log_user 1
send "$PASSWD\r"
expect -re " $"
set val $expect_out(buffer)
send_user "$val"
send "exit\r"
close
EXPECTEND);echo "$VAL"
