Hi Daniel, I increased the size of your test to be 128 but -stats still shows no loop optimized...

I need to review a logfile with Sed and cut out all the lines that start with a certain word, problem is this word begins after some amount of whitespace and unless I search for whitespace at the beginning followed by "word" I may encounter "word" somewhere legitimately hence why I don't just search for "word" only... Anyone know how to make sed accomplish this?

...here. Note there is one nasty catch with error(3): error (EXIT_SUCCESS, ...) does *not* exit! This is also the reason why error(3) cannot be marked as __attribute__((noreturn)). Because the examples can't use gnulib, I did not change them. To search for multiline patterns of the above form, pcregrep -M turns out to be very useful: pcregrep --buffer-size 10M -M '\bperror\b.*\n.*\bexit\b' `git ls-files` --- builder/index-validate.c | 7 +- cat/cat.c | 19 +-- cat/filesystems.c | 67 ++++----...

...ly being ignored, in which case I have fixed that). It's slightly more complex than the previous commit because we must be careful to: - Remove the program name (since error(3) prints it). - Remove any trailing \n character from the message.
