sexpect - expect alternative in shell

While looking for solution on terminal window resize using expect, found an alternative tool - sexpect. Despite the naming, a great tool actually.

Actually helps me to solve many issues and more of all - combine shell and expect-like scripts in 1 file.

Just to show an simple example (yes, I'm aware of ssh keys):

shell + expect:

#!/bin/bash

...
SSH_PASS=XXXXX
SSH_ADDR=YYYYY

expect <(cat << EOD
    spawn ssh $SSH_ADDR
    expect "Password:"
    send -- "${SSH_PASS}\n"
    interact
EOD
)

shell + sexpect

#!/bin/bash

...
SSH_PASS=XXXXX
SSH_ADDR=YYYYY

export SEXPECT_SOCKFILE=/tmp/sexpect-$$.sock

type -P sexpect >& /dev/null || exit 1

echo "Connecting to $SSH_ADDR..."

sexpect spawn -idle 120 -t 60 $SSH_ADDR

 if [[ $? != 0 ]]; then
    echo "Spawn failed!"
    exit 1
fi

sexpect expect -ex "Password:"
if [[ $? != 0 ]]; then
    echo "Nowhere to enter password!"
    exit 1
fi

sexpect send -enter "$SSH_PASS"

sexpect set -idle 5
sexpect interact

As a bonus - terminal window resize work as expected.
