fish shell extension for printing timing information for each command line executed.
After the execution of each command line, the script prints out the total
execution time (up to millisecond precision), followed by the current time. The
execution time is formatted to be human readable; e.g., 2h 7m 42s301
.
Demo:
Additionally, the script will export the total execution time (as a human
readable string, e.g., 42s027
) as $CMD_DURATION_STR
. You can use this
variable in your subsequent prompt.
This script requires fish shell 2.2 or above. It should run pretty much out of the box on modern Linux and Mac OS X systems. Please report any incompatibilities on on GitHub.
To set up this extension, you can
- Download
conf.d/fish_command_timer.fish
and put it in~/.config/fish/conf.d/
as per Fish shell convention. - If the above doesn't work for you (perhaps because your custom settings overrides the extension), you could try sourcing it directly. Download
conf.d/fish_command_timer.fish
and put it in~/.config/fish/
, then add the following in your~/.config/fish/config.fish
at the end:source ~/.config/fish/fish_command_timer.fish
That's it :)
You can use the following options to tweak the behavior of the script.
Put them in your config.fish
.
You can also modify them on-the-fly if you want the changes to only affect your current shell session.
set fish_command_timer_enabled
: Setting this variable to0
disables printing of measured time.set fish_command_timer_color blue
: The color of the output. This should be a color string recognized by fish's set_color command, as described here. If not set, the output will be in the default color.set fish_command_timer_time_format '%b %d %I:%M%p'
: The display format of the current time. This is a strftime format string (see http://strftime.org/). If empty, the current time will not be printed.set fish_command_timer_millis
: Whether to print timings to millisecond precision. If set to0
, will print timings up to seconds.set fish_command_timer_export_cmd_duration_str
: If set to1
, will export the total command execution time string to$CMD_DURATION_STR
, for use in prompts. If set to0
, the$CMD_DURATION_STR
variable will not be exported.
Setting fish_command_timer_enabled
to 0
and fish_command_timer_export_cmd_duration_str
to 1
allows printing the time in the subsequent prompt without also having it printed after the command completes.
