expect -re causes error
Hi there. Following part of my code causes script to abort. Why?
Code:
expect -re 'Netroup[^a-zA-Z]permissions[^a-zA-Z]list' {send "$ntgr\r"}

Code:
invalid command name "^a-zA-Z"
    while executing
"^a-zA-Z"
    ("foreach" body line 2)
    invoked from within
"foreach ntgr $netgroup {
expect -re 'Netgroup[^a-zA-Z]permissions[^a-zA-Z]list' {send "$ntgr\r"}
sleep 1
}"
    (file "./useradd.exp" line 23)
