Top Forums Shell Programming and Scripting Large Variable content size caveats? Post 303031979 by Corona688 on Friday 8th of March 2019 10:58:00 AM

Main caveat, it's almost almost always a dumb idea. Ad-hoc data, "dump-and-fix-later", is the modern UUOC, wasteful and pointless. If you know what you actually want, you can either deal with it in a structured way or avoid storing it entirely.

Another caveat, most shells don't let you keep binary data in variables. Mass dumping unchecked data into variables can occasionally surprise you.
