Example text

Individual programmers can contribute by writing a compatible duplicate of some Unix utility and giving it to me. For most projects, such part-time distributed work would be very hard to coordinate; the independently-written parts would not work together. But for the particular task of replacing Unix, this problem is absent. Most interface specifications are fixed by Unix compatibility. If each contribution works with the rest of Unix, it will probably work with the rest of GNU. If I get donations of money, I may be able to hire a few people full or part time.

NetBSD is the most portable of the BSDs, running on PC, Alpha, and PowerPC, as well as ARM, HPPA, SPARC/SPARC64, Vax, and many others. Proprietary Unix Oracle Solaris traces its roots back to 1983, and is arguably the most feature-full and actively developed enterprise OS on the market today. SunOS was originally based on BSD, but with the move to Solaris switched to the System V flavor of Unix. Solaris today comes with the original Bourne shell as /bin/sh, as well as ksh93, bash, csh, tcsh, and zsh shells.

In your PATH, especially at the front of the PATH. If you change into a directory and run a command (maybe ls), any program in that directory called ls will be run, and not the system /bin/ls program. ). Also, it is better to keep the system directories such as /usr/bin and /bin at the start of the PATH so that local scripts do not override system default ones. Therefore, use the syntax PATH=$PATH:${HOME}/bin rather than: PATH=${HOME}/bin:$PATH Tool-Specific Variables Many system tools have their own variables; less adds the value of $LESS to its commands.
