This is not strictly true.  There is no limit imposed by bash; but
there is a limit imposed by the *kernel* on the total size of the
environment plus the argv[] argument vector passed to a process.

<https://www.in-ulm.de/~mascheck/various/argmax/> documents this
extremely thoroughly.

In most cases, when a problem arises with hitting this limit, it's
because the argument list is too long, not the environment.  You seem
to be hitting it from the other direction, though.

Solution: "don't do that".

Well... that sounds like you're filling up the table of exit statuses
that have been reaped internally.  I think there might have been some
bugs in older versions of bash concerning this issue as well.

Some people have reported this issue when they run an infinite loop with
an external command inside it (e.g. sleep).

I don't recall off the top of my head how to work around this issue, if
you're writing "daemon scripts" that run forever and spawn external
commands within a loop.  You might need to Google it.  It's a bit
esoteric.

Huh?  I have no idea what this means.  Bash doesn't have a limit on the
number of aliases you can define, as far as I know.

Aliases do not work in shell scripts, by default.  You would have to turn
them on with a shopt.  I recommend not doing that.  They're disabled
because they suck.  Use functions instead of aliases, when writing scripts.
They're far more sensible and flexible.
