Shorter Hacks 4: Strace only failed syscalls

Want to see why some program is failing? Strace often has the information, but the output is too much to read. You can use the option -Z to limit output to failed syscalls only. -z on the other hand limits to successful syscalls.

The series Shorter Hacks consists of tips and tricks for Linux nerds. Flags, hacks, and features of everyday tools that you might not know already, but that will enrich your life. I currently have a list of around 40 hacks I collected and plan to publish them roughly weekly. In order for this series to continue, please send me your best trick(s). The focus is not on fancy new tools or extensive rc-file content, but little known features in software most people already use. Send them to michael bei schoenitzer punkt de.
This blog has an Atom-Feed and I plan to also post the Shorter Hacks articles on Mastodon and Twitter.
