VERSION:
GNU bash, version 3.00.15(1)-release (i386-redhat-linux-gnu)
{came with Red Hat EL-4}
Description:
Valid math operations results give an ERROR exit status.
While this is a documented feature [4.2 of the info file]
If the last EXPRESSION evaluates to 0,
`let' returns 1; otherwise 0 is returned.
grr grrr ... it was not expected, and bash treats it as an ERROR
bash$ let A=1-1
bash$ echo $?
Info file: "6.5 Shell Arithmetic" where available operators are
listed implies that the only "error" that can occur is division by
zero.
"[snip] with no check for overflow, though division
by 0 is trapped and flagged as an error."
Implies otherwise.
Thanks.
