john pfeiffer 2009-11-24 script(s) to add user to an htpasswd file

the script will wait 1 second for any command to finish

set timeout 1 set username [lindex $argv 0] set userpass [lindex $argv 1]

the two parameters are the new username and password

we are creating a thread specifically to run the next script as the user "scriptuser"

spawn su scriptuser -c "/path/wiki-add-user.sh $username $userpass"

it is KEY to get the exact text of the "expect" line right, in this case, notice the trailing space

expect "Password: " send "password\n"

the expect script "catches" the prompt by SU for the password - you need the newline \n

the script must sleep for 1 second at the end to allow the "spawned" thread to finish

every "spawn" command requires an interact command to give control back to the prompt

sleep 1 interact
