I noticed that for aliases etc the title of a Terminal tab/window often isn't the same as the command I typed. This is sometimes confusing, especially for long-running processes with similar names.
So how can I configure
bash/Terminal in a way which ensures that the window title always reflects the command as typed?
When I type
python -m SimpleHTTPServerand press Return in a Terminal window, the tab of that Terminal window should show "python -m SimpleHTTPServer" immediately.
When I type
flushdns, which is my alias for
sudo killall -HUP mDNSResponder;sudo killall mDNSResponderHelper;sudo dscacheutil -flushcacheand press Return in a Terminal window, the tab of that Terminal window should show "flushdns" immediately.
What I tried:
I tried modifying
PS4 to run a command. This works, however it also prints a lot of other garbage, like getting the current git branch and other commands I put in my
PS1. If there's a way for
PS4 to only run scripts and not output anything (not even line breaks) I'm fine with that too as a solution.
I also tried the various options under Preferences > Profiles > Tab, but it does not allow showing the literal command I just entered.
