The GNU C Library project provides the core libraries for the GNU system and GNU/Linux systems, as well as many other systems that use Linux as the kernel. These libraries provide critical APIs including ISO C11, POSIX.1-2008, BSD, OS-specific APIs and more. These APIs include such foundational facilities as open, read, write, malloc, printf, getaddrinfo, dlopen, pthread_create, crypt, login, exit and more.

POSIX compatible regexp library with approximate matching
TRE is a lightweight, robust, and efficient POSIX compatible regexp matching library with some exciting features such as approximate matching.
The agrep tool is similar to the commonly used grep utility, but agrep can be used to search for approximate matches. The agrep tool searches text input for lines (or records separated by strings matching arbitrary regexps) that contain an approximate, or fuzzy, match to a specified regexp, and prints the matching lines. Limits can be set on how many errors of each kind are allowed, or only the best matching lines can be output. Unlike other agrep implementations, TRE agrep allows full POSIX regexps of any length, any number of errors, and non-uniform costs.
