期望与SJWS wadm命令

Question

I'm using expect in the very traditional way of match string, send desired inputs within a bash script wrapping around iplanet/SJWS wadm command, which itself is a bash script calling a java program.

Rather than when I run the program manually, certain components such as passwords get echoed back to the shell and the control characters don't seem to be sent.

I think it might be a multiline regexp issue, but using a wildcard at the front of the expect doesn't seem to work, and using the debug option (when sending a password string) has the expect comparing the password with the string I want to match it to.

I don't have much experience with expect and was hoping if anyone had seen this issue before.

Thanks

Assuming that:

• you are using Unix environment;
• you have no problems running an expect file, instead of expect one-liners;
• you run the following script from the path in which wadm script is found;

This will probably suit your needs:

reset.exp

#!/usr/bin/expect

if {$argc != 1} {
    puts "Usage: expect $argv0 password"
    exit 1
}
set PASSWD [lindex $argv 0] ;# get password from the first argument

spawn -noecho $env(SHELL) ;# spawn a new process, in order to use send/expect
set timeout 10     ;# short one (10 s)
log_user 0         ;# disable showing up sensitive info (PASSWD value)

set cmd "wadm reset-admin-password" ;# put the command string into a variable
send "$cmd\r"
expect {
    -regex "enter admin-password.*$" {
        puts "Got the password request ..."
    }
    timeout {
        puts "ERROR: Timeout reached during running $cmd !"
        exit 1
    }
}
send "$PASSWD\r"
expect {
    -regex "enter admin-password again.*$" {
        send "$PASSWD\r"
        expect -re ".*$"
        # TODO: define reject/accept patterns
        puts "Password accepted!"
    }
    timeout {
        puts "ERROR: Timeout reached on entering password!"
        exit 1
    }
}
send "exit\r"
expect eof

And managed to get things resolved, the wadm command appears to make a soap connection that slows things down, so

/usr/bin/expect << EOD
set password $PASSWD
spawn $BINDIR/wadm reset-admin-password
sleep 1
expect -re ".*admin-password> " {send -- "$password\r"}
expect -re ".*admin-password again> " {send -- "$password\r"}
expect -re ".*CLI" {send -- "exit\r"}
interact
EOD

Thanks for the help!
