Details:
The following example gives a segfault in GNU grep (v2.6.3):
echo hi | grep -Fi -f /tmp/
Of course, that is an incorrect grep invocation, but the behavior is
inconsistent with this example:
echo hi | grep -Fi -f /tmp/
Here grep fails with exit code 1 as if there were no matches.
I recommend just adding a simple check that the filename argument of the -f
option does in fact refer to a regular file.
Thanks,
Bake Timmons
