Hi all-

I'm writing a command where it would be really great to preserve a string for later use by other commands.

I'm assuming there no way to define a environment variable (like LAST_STAMP or something) that could be set from a command, would persist, and could be read from a later invocation of another command?

Any other kind of scratchpad memory that I could take advantage of? (I realize I could write a small file somewhere.)

Many thanks in advance!

Charles
