Manage signals before running programs (a generic "nohup")

View on GitHub


A small utility akin to nohup: quickly set up the signal block mask & signal dispositions before executing another program.

See the man page for a lot more technical detail.


nosig should be usable on any recent POSIX compliant system. C11 & POSIX/IEEE Std 1003.1-2008 are the current requirements.

There is no desire to port to any non-POSIX system (e.g. Windows).

Your C library will also have to support getopt_long via getopt.h.
