When I open gnome-terminal, instead of presenting me with my default Bash shell, it shows:


This began happening since I added DISPLAY=:0 to my crontab -e file which now looks as follows:


0 0,6,12,18 * * * /usr/bin/gnome-terminal -e /home/orschiro/bin/updates.sh
0 0,6,12,18 * * * /usr/bin/gnome-terminal -e /home/orschiro/bin/rclone.sh

And also of interest:

sh-4.4$ ls -l /bin/sh
lrwxrwxrwx. 1 root root 4 18. Jun 10:30 /bin/sh -> bash

This question came from our site for Ubuntu users and developers.

  • Please edit and add the output of grep $(whoami) /etc/passwd and cat ~/.bashrc using the formatting tools. – dessert Jul 4 '18 at 12:03

    This is your default bash shell. Probably you have tinkered with PS1 in .bashrc or .profile. – Soren A Jul 4 '18 at 12:11

    I think you are right. See my edits. I am on Fedora 28. Maybe that's the default symlinked behaviour? – orschiro Jul 4 '18 at 12:40

    So, this isn't about Ubuntu at all then? – steeldriver Jul 4 '18 at 12:41

    Also, why, oh why, do you run the scripts in a terminal emulator from your crontab. That's totally unnecessary. – Kusalananda Jul 4 '18 at 14:18

I'm assuming this is the gnome-terminal started from your cronjob.

There is absolutely no need to run the cronjob scripts inside gnome-terminal. Doing so would mean that the jobs would fail if gnome-terminal could not be opened (which would probably happen if you weren't using the desktop at the time).

Just use

0 0,6,12,18 * * * "$HOME"/bin/updates.sh
0 0,6,12,18 * * * "$HOME"/bin/rclone.sh

Any output from the scripts will be emailed to you, assuming local email delivery was enabled. To save the output to a log file, use a redirection:

0 0,6,12,18 * * * "$HOME"/bin/updates.sh >>"$HOME"/updates.log"
0 0,6,12,18 * * * "$HOME"/bin/rclone.sh  >>"$HOME"/rclone.log"

The environment that the cronjobs are running in is different from the one you usually have when logged in through a graphical desktop environment. For one thing, your default shell may not be set in the SHELL environment variable, which is why gnome-terminal starts /bin/sh instead of bash (sh is bash on your system, but runs in POSIX compatibility mode when invoked as sh).

When logged in on the graphical desktop environment, opening gnome-terminal as usual would give you your default shell. If it doesn't, it's because there's a gnome-terminal-server process running which was started by the cron jobs. Terminate this process by either rebooting or by using pkill -f gnome-terminal-server.
