Expect : exp_external not working / If not showing error
The big problem is that exp_internal isnt working... which makes it difficult to determine whats happening with the if statement.

1. why isnt exp_internal not working ?
2. Is there a better way to do the check of a file ?

Im trying to find a "tighter" way to check that a file exists and has content. Didnt want to post in
https://www.unix.com/shell-programmin...-ksh-if-s.html

because of the more important exp_internal issue.



Code:
#!/usr/bin/expect
exp_internal 1
set nam "popeye"
set pswd "thesailorman"
set hlist "hostlist"
set clist "cmdlist"
send_user "$clist\n"
if { [llength $clist] <= 0 } {
         send_user " empty or not found."
      }
exp_internal 0
close

The script output
Quote:
/home/popeye> tnew
cmdlist

Quote:
/home/popeye> ls -l cmdlist
ls: cannot access cmdlist: No such file or directory

expect1.1> llength cmdlist
1
expect1.2> exit

Thanks Regards
