1) be stricter which number of arguments is accepted (1 or 2) 2) basename already returns a pointer to "." is argv[0] is "" 3) No need to check for *p != '/', because basename() only returns a string beginning with '/' which has length 1, so if strlen(p) == 1, the only way for suffix to be "evaluated" is for off to be > 0, being equal to suffix being "", but "" != "/". 4) don't calculate strlen twice for each string. Store it in a ssize_t and check if it's > 0. |

sbase - suckless unix tools
===========================
sbase is a collection of unix tools that are inherently portable
across UNIX and UNIX-like systems.
The following tools are implemented ('*' == finished, '#' == UTF-8 support,
'=' == implicit UTF-8 support, '|' == audited):

The complement of sbase is ubase[1] which is Linux-specific and
provides all the non-portable tools. Together they are intended to
form a base system similar to busybox but much smaller and suckless.
Building
--------
To build sbase, simply type make. You may have to fiddle with
config.mk depending on your system.
You can also build sbase-box, which generates a single binary
containing all the required tools. You can then symlink the
individual tools to sbase-box.
Ideally you will want to statically link sbase. If you are on Linux
we recommend using musl-libc[2].
Portability
-----------
sbase has been compiled on a variety of different operating systems,
including Linux, *BSD, OSX, Haiku, Solaris, SCO OpenServer and others.
Various combinations of operating systems and architectures have also
been built.
You can build sbase with gcc, clang, tcc, nwcc and pcc.
