Hi all,

Sorry for this off topic post, but I've been asked how/where to find maximum
size of bash variable value. I've search and found 4M, 1k, 4k ... . But didn't
found how/where this limit is set. I know, that for C it's e.g. sizeof(int),
but for bash?

Thanks for help

Pat

afaik you can query that value with
getconf ARG_MAX
How to set it, I have no idea.

Thanks for help
