Prevent TMUX from starting in intellij terminal

So I have the following snippet:

if [[ ps -p$PPID | grep 'java' == '' ]]; then
    ZSH_TMUX_AUTOSTART=true;
fi

which returns the following error:

/home/otis/.zshrc:8: parse error: condition expected: ps

The idea is that if ps -p$PPID | grep 'java' returns nothing then set ZSH_TMUX_AUTOSTART=true.

The reason I want to do this is I want to automagically start tmux in my gnome-terminal but not in my intellij terminal if I run this command in gnome it returns nothing and if I run from intellij it returns java.

So the logic is solid basically if there is nothing returned always start tmux, but I am not that good at shell so any help would be much appreciated.

Cheers.

In your project, under Settings > Tools > Terminal, set Environment variables to INSIDE_EMACS=true.

I realize this is an old thread and the TERMINAL_EMULATOR variable may not have been the same at the time of the original post but I solved this on OSX with the following:

if [ "$TERMINAL_EMULATOR" != "JetBrains-JediTerm"]
then 
   ZSH_TMUX_AUTOSTART=true
fi

The reason you get an error message is due to the conditional expression ([[ … ]]) expecting a condition after ps, which it takes for a string not a command. You have to wrap the command in $(…) to use its output inside the conditional expression. Alternatively you could just use the exit code of grep to determine whether "java" has been found, which removes the need for a conditional expression.

if ! ps -p $PPID | grep -q java; then
    ZSH_TMUX_AUTOSTART=true;
fi

Note that the the return values of the check are reversed to what you originally intended. Hence the ! to return true if the exit code would be false and vise versa. -q just suppresses the output of grep.
