Hiltjo Posthuma 97fb4a1f9c grep: improvements
improvements:
- improve statuscode behaviour
  - don't exit if a file in a series fails. exit 2 if an error occured
    in a file series. don't exit if there is a read error (like: grep
     input file is a directory).
- use agetline instead of agets().

with the simple test: time seq 1 100000000 | grep 'a'
its 12 seconds (from 24 seconds) on my machine.

sbase - suckless unix tools
===========================

sbase  is a  collection of  unix  tools that  are inherently  portable
across UNIX and UNIX-like systems.

The following programs are currently implemented:

    basename cal  cat chgrp chmod chown  chroot cksum cmp comm  cp cut
    date dirname du  echo env expand false fold grep  head hostname id
    kill ln  ls mc md5sum mkdir  mkfifo mktemp mv nice  nl nohup paste
    printenv  pwd readlink  renice rm  rmdir sleep  setsid sort  split
    sponge strings sync  tail tar tee test touch tr  true tty uudecode
    uuencode  uname uniq  unlink  seq sha1sum  sha256sum sha512sum  wc
    xargs yes

sbase is mostly following POSIX but we deviate wherever we think it is
appropriate.

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.

sbase  also compiles  and runs  on minix3  with slight  modifications.
They do  not provide mmap()/munmap()  so you need to  use minix_mmap()
and minix_munmap() respectively.

Various combinations of operating  systems and architectures have also
been built.

You can build sbase with gcc, clang, tcc, nwcc and pcc.
