The exit status of the last run command substitution is available in the :ref:`status <variables-status>` variable if the substitution happens in the context of a :ref:`set <cmd-set>` command (so ``if set -l (something)`` checks if ``something`` returned true).

Fish has a default limit of 100 MiB on the data it will read in a command sustitution. If that limit is reached the command (all of it, not just the command substitution - the outer command won't be executed at all) fails and ``$status`` is set to 122. This is so command substitutions can't cause the system to go out of memory, because typically your operating system has a much lower limit, so reading more than that would be useless and harmful. This limit can be adjusted with the ``fish_read_limit`` variable (`0` meaning no limit). This limit also affects the :ref:`read <cmd-read>` command.
