But what do you want BASH to do about it? BASH is a generalized command processor. You have found that it is possible to give a "reasonable" command which exhausts your available memory. No offense intended, but _I_ would consider that a "user error". It is no different from what I saw on another forum for the R language. The user exhausted memory by trying to read in a CSV file, the entire thing at once, which was about 1 million lines (rows) containing hundreds of values per row. Solution: buy a more powerful computer with, say, about 512 GiB of memory. It'll only set you back about $2,000 U.S.; example (not recommendation): http://www.thinkmate.com/system/rax-xs4-1160v4. Honestly: you need to change your algorithm for processing your problem. In your example, perhaps a series of nested loops. -- "Irrigation of the land with seawater desalinated by fusion power is ancient.
