Executing script with terminal via command option

  • 772

I implemented the answer to this question and now the title bar is gone from the terminal. I found that the python script decorator.py had to execute twice to have the effect applied. Rather than tapping out ./decorator.py twice every time I started a new terminal, I created maximize to execute the script twice. This script is hotkeyed to Ctrl-Alt-Y.

Currently I've used

gnome-terminal --maximize -e /home/jason/maximize

gnome-terminal --maximize -x /home/jason/maximize

as arguments for Ctrl-Alt-T.

The issue is I can see the outline of a new terminal flash on screen, but it doesn't exist for more than a fraction of a second. How can I make the new window more persistent?

command-line

    The -x option to gnome-terminal or, similarly, the -e option to other xterm-compatible terminal applications, tell the terminal emulator to start the command following the -x/-e option and then exit. This is the reason why you're seeing the terminal outline flash and disappear: the terminal starts, maximizes, then exits.

    You could instead include the maximize command into your .bashrc or .profile, so that it is executed every time a shell is started.

    However, since it executed each time a shell is started, you need to find a way to execute it only when the shell is started from the terminal application. On my Ubuntu 11.04 system the following does the trick:

    if [ -n "$DISPLAY" ] && [ "$SHLVL" = 1 ]; then
  # the following commands are only executed when
  # the shell runs inside a terminal
  maximize
fi

    The -n "$DISPLAY" part tests if there is a graphical X11 display active, and the $SHLVL part checks if this shell is 1st level shell, i.e., a direct child of the terminal application (a shell may start another shell for running commands or script, but in this case the $SHLVL value will be larger than 1).
