patch taken from openbsd. Ingo Schwarze says: If you call the col(1) utility with the -f option, permitting forward half-line feeds in the output stream, and the input stream actually contains half-line feeds in either direction, you end up with corrupt output, containing meaningless escape-digitnine sequences instead of the required escape-tab sequences. $ hexdump -C half.txt 00000000 61 1b 09 62 1b 09 63 0a |a..b..c.| 00000008 $ col -f < half.txt | hexdump -C 00000000 61 1b 39 0d 20 62 1b 39 0d 20 20 63 0a |a.9. b.9. c.| 0000000d Note how the third character changes from 0x09 to 0x39. OK to commit the following fix? Don't worry, it isn't dangerous, it only changes two *bits*, only a quarter of a byte. The bug was introduced by the original author, Michael Rendell, and committed by Keith Bostic on May 22, 1990 (SCCS rev. 5.1). The following operating systems are affected: * 4.3BSD Reno, BSD Net/2, 4.4BSD, 4.4BSD Lite1, 4.4BSD Lite2 * All versions of 386BSD, NetBSD, OpenBSD, FreeBSD and DragonFly * All versions of Debian GNU/Linux and probably many other Linuxes
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 col cols comm cp csplit cut date dirname du echo env expand expr false fold grep head hostname kill link ln logname ls md5sum mkdir mkfifo mktemp mv nice nl nohup paste printenv printf pwd readlink renice rm rmdir sleep setsid sort split sponge strings sync tail tar tee test touch tr true tty uudecode uuencode uname unexpand 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. [1] http://git.suckless.org/ubase/ [2] http://www.musl-libc.org/
