I'm trying to run the following:

if [! -f .owner ]; then
    sudo -u appuser ksh
    echo "$creator" >> .owner
    mkdir test1 test2 test3

However, the file/folders get made by the person that runs the script. Any way to make these get created by appuser?

Edit: sudo -l returns (appuser) NOPASSWD: ALL

  • you can just change the owner at the end of the script. – Rabin Jul 22 '14 at 20:17
  • you could run your script using sudo and then use su inside your script – Kiwy Jul 23 '14 at 8:20
  • Users running this script won't be super users, the appuser account itself is also not a super user. Chown isn't available to unprivileged users. The purpose for this script is that the appuser creates a whole bunch of files when it first gets ran (hence the need to track the person that called the job). The folder these files are located in have read-only access to their common group. – charles Jul 23 '14 at 13:08


    touch script-run-user.file

    sudo -u appuser 'ksh' <<EOF
    # add list of cmds to execute
    touch appuser.file 

Edit: Just as an update, check out Here Documents. EOF = "End Of File", the name is arbitrary.

  • This is correct - but this is just a note that the reason this works and the other didn't is that the >> means the shell creates the file - and its process is owned by the user invoking the script so files it creates are owned by that user, but here you change users then invoke touch - which also creates files owned by the user invoking it. – mikeserv Jul 22 '14 at 21:06
