Значок jetbrains studio появляется, когда я запускаю android-studio

Самое близкое, что я вижу, похоже на set -o xtrace в zsh , позвонив по номеру ] fish с помощью -d 4 или - debug-level = 4 :

$ fish -d 4 -c 'echo 1'
fish: Exec job 'builtin source /usr/share/fish/config.fish 2>/dev/null' with id 1
fish: Exec job 'set -g IFS \n\ \t' with id 2
fish: Set status of set -g IFS \n\ \t to 0 using short circuit
fish: Job is constructed
fish: Continue job 2, gid 0 (set -g IFS \n\ \t), COMPLETED, NON-INTERACTIVE
...
fish: Exec job 'echo 1' with id 1
1
fish: Set status of echo 1 to 0 using short circuit
fish: Job is constructed
fish: Continue job 1, gid 0 (echo 1), COMPLETED, NON-INTERACTIVE
