When you use this syntax, you're forcing "time" to be evaluated as a regular command instead of a keyword. Here's the keyword: hobbit:~$ time --version bash: --version: command not found real 0.002 user 0.000 sys 0.002 Here's the external /usr/bin/time (on Debian 13): hobbit:~$ /usr/bin/time --version time (GNU Time) UNKNOWN ... And here's the syntax you were trying to use: hobbit:~$ x=y time --version time (GNU Time) UNKNOWN ... As you can see, it uses the external /usr/bin/time.
