Before removing bit fields: $ size find text data bss dec hex filename 16751 968 48 17767 4567 find After removing bit fields: $ size find text data bss dec hex filename 16527 968 68 17563 449b find This is an example where bit fields uses more memory than integers or char. There is going to be only one gflags struct, so the waste in instructions is bigger than the space saved by bit fields. In the case of Permarg, Sizearg, Execarg there is only one bit field, so at least one unsigned is used, so there is no any gain. |

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):

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.
