Ubuntu – Option “-e” is deprecated and might be removed in a later version of gnome-terminal in Ubuntu 18.04

gnome-terminal

This title has a duplicated question and confirmed as a bug. But it was in Ubuntu 17, mine is Ubuntu 18.04 LTS. So I guess the bug in the old question is fixed. Bug I still encounter it, so here is my problem:

File disk.desktop >>

[Desktop Entry]
Name=Disk Manager
Comment=Open df cmd in Terminal
Icon=harddisk
Type=Application
Categories=Utility;Management;
Keywords=disk; manager; terminal;
StartupNotify=true
Exec=gnome-terminal -t "Disk Manager" --hide-menubar -e "df -h --output=source,used,size,avail,target -x devtmpfs -x tmpfs -x squashfs"

The star is in the last line:
gnome-terminal -t "Disk Manager" --hide-menubar -e "df -h --output=source,used,size,avail,target -x devtmpfs -x tmpfs -x squashfs"

My command is run gnome-terminal which execute the df app with a few arguments of it. The .desktop file has a very weird behavior. It simply does nothing, not even firing error code.

If I remove all of its arguments except the -h, it works some times. If I run df app in a running terminal, it runs very well. So my money's on gnome-terminal's fault.

I decided copy my whole command to an running terminal. And the result is half-title:

# Option “-e” is deprecated and might be removed in a later version of gnome-terminal.
# Use “-- ” to terminate the options and put the command line to execute after it.

Since I got no error code. I have no idea what to do next. Please tell me how to fix it. Thanks.

Update 7-Feb-2019 ::

Follow @vidarlo advise, I've changed to option flag --. Here is the result:

  • -- doesn't work with command within the " " quote. It returns a fail execution error: Fail to execute child process "df -h"
  • I couldn't find any doc for this option. Not in man not in --help-all. It seems to me that this flag is not standard yet.

What I look for is an option allow me to pass command with a few arguments. In Lubuntu, it looks like this lxterminal -e "df -h -x devtmpfs -x tmpfs -x squashfs".

Read the error message:

# Option “-e” is deprecated and might be removed in a later version of gnome-terminal.
# Use “-- ” to terminate the options and put the command line to execute after it.

The error message tells you that -e is deprecated, and may be removed in future versions, and the alternative to -e.

You have the following command line:

Exec=gnome-terminal -t "Disk Manager" --hide-menubar -e "df -h -- output=source,used,size,avail,target -x devtmpfs -x tmpfs -x squashfs"

Change this to

Exec=gnome-terminal -t "Disk Manager" --hide-menubar -- "df -h --output=source,used,size,avail,target -x devtmpfs -x tmpfs -x squashfs"
