Re: Max length of os.execute command

[Paco Zamora Martínez <pakozm@...>]

How large is your command? We have a large project in C++ with Lua and we use os.execute with very large commands with at most 6433 characters, and we are not suffering any limit problem...

os.execute will use sh -c '...'. So it could be a shell limit on the maximum
length of a single command argument. Invoking the same command from an
interactive shell works quite differently; for one thing, it's parsed
entirely differently.
