I work with the command line a lot (as do/should most developers, at least if they’re not running Windows). Every once in a while I happen to run a command which takes longer to complete than I expected. When that happens I want to know how long it took/when it started. For this, I formatted my zsh prompt in the following way:
And in plain text:
(I’m using iTerm 2 with the “Pastel (Dark Background)” color preset.)
My prompt always contains the current date-time and directory. This helps when you end up with a long-running command you didn’t plan for (an example I had the other day was a jmap heap dump, which took a surprisingly long time). I’d love to also have milliseconds in there, but it seems like zsh is using strftime(3) which doesn’t have anything shorter than seconds.
I also like having the current directory to remember where I am – helpful with many open terminal tabs/windows.
To get this prompt format, edit
~/.zshrc and add the following to it:
Every new zsh instance you start from now on will have the new format. You can easily change the colors/date-time format if you want.
