I don't think so. To proof it, I created this user: nologinuser:x:1015:1016::/home/nologinuser:/sbin/nologin Then I created this script: #!/bin/sh # date >> /home/nologinuser/envars.txt echo $HOME >> /home/nologinuser/envars.txt echo $PATH >> /home/nologinuser/envars.txt echo "-----------------------" >> /home/nologinuser/envars.txt I stored it as /var/script-nologinuser/testscript.sh. I had to store it at this place because /home is mounted with the noexec option on my system. Then I created a cronjob for the nologinuser user: */2 * * * * /var/script-nologinuser/testscript.sh The result is the file /home/nologinuser/envars.txt with this content: Wed Jul 13 18:10:01 CEST 2016 /home/nologinuser /usr/bin:/bin ----------------------- Wed Jul 13 18:12:01 CEST 2016 /home/nologinuser /usr/bin:/bin ----------------------- The ownership and the rights for /home/nologinuser/, /var/script-nologinuser/ and /var/script-nologinuser/testscript.sh are nologinuser:nologinuser and 700. So it seems, that it is possible to execute scripts without setting a shell in /etc/passwd. I don't know why it doesn't work for jens w. -- Regards wabe
