# Program: grep-not
|
|
#
|
|
# Synopsis: Search the input to the program for a regular expression, working
|
|
# just like grep. The only difference is that we return success if
|
|
# the pattern was not found, and failure if it was. This is useful
|
|
# for TestRunner tests which want to make sure something DOES NOT
|
|
# occur in the output of a command.
|
|
#
|
|
# Syntax: The same as grep
|
