Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
``time`` causes fish to measure how long a command takes and print the results afterwards. The command can be a simple fish command or a block. The results can not currently be redirected.
|
||
|
|
|
||
|
|
For checking timing after a command has completed, check :ref:`$CMD_DURATION <variables-special>`.
