substr
An utility to extract substring from a string, inspired by the GNU
expr extension of the same name. This implementation is under
the ISC licence.
Read the man page for more information with either mandoc(1) or groff(1):
$ mandoc substr.1 | less
$ groff -m mdoc -Tascii substr.1 | less
In order to run on Linux systems the libbsd package should be installed first.
Installation
On OpenBSD:
$ make && doas make install
On Linux:
$ LDADD=-lbsd CFLAGS="-D NEED_LIBBSD" make && sudo make install
Example
$ substr hello 1 2
he
$ substr "Omelette du fromage" 13 7
