I am trying to run commands as sudo over SSH, without success:

ssh -t -p 2222 name@server /usr/bin/sudo << EOF
  chmod u-r /xy 
  chmod +x /xy
  /xy
  sleep 5
  ps aux | grep xy
  sleep 5
  exit
EOF

This is not working. Without -t and /usr/bin/sudo:

sudo: no tty present and no askpass program specified

Single line command is working:

ssh -p 13001 -t name@server 'sudo /xy'

This should work:

ssh -t -p 2222 name@server "/usr/bin/sudo bash -c 'chmod u-r /xy; chmod +x /xy; ...'"
  • +1: ssh -t name@server "sudo command here" worked for me – Robbie Averill Nov 13 '14 at 2:00
