Thread: expect in a useful way?

so wondering. expect designed do? specifics please.

have no problems it, logging remote system, or downloading files remote site.
when try edit on remote system, creating file. nothing.

example note $amount equals decimal value no colons or anything.

code:

/usr/bin/expect - << endmark  set timeout 1  exp_internal 1  spawn /usr/bin/ssh -f root@ip "/bin/ls /path/ |/bin/grep x_ |/usr/bin/head -n $amount > /path/test"  sleep 1  expect "root@ip's password:"  sleep 1  send "password\r"  sleep 1  endmark

but docent create file @ remote site.
output get

code:

spawn /usr/bin/ssh -f root@ip /bin/ls /path/ |/bin/grep x_ |/usr/bin/head -n 5 > /path/test  parent: waiting sync byte  parent: telling child go ahead  parent: unsynchronized child  spawn: returns {4060}    expect: "" (spawn_id exp4) match glob pattern "root@ip's password:"? no  root@ip's password:   expect: "root@ip's password: " (spawn_id exp4) match glob pattern "root@ip's password:"? yes  expect: set expect_out(0,string) "root@ip's password:"  expect: set expect_out(spawn_id) "exp4"  expect: set expect_out(buffer) "root@ip's password:"  send: sending "password\r" { exp4 }

why cant run commands in expect can run hand?
up-to-date useful expect guides?

kind regards.
