UNIX to Plan 9 command translation
D1373207366
Astevie
#The command set of Plan 9 is similar to that of UNIX. The commands
#fall into several broad classes.
#
#Some are new programs for old jobs: programs like ls(1), cat(1), and
#who(1) have familiar names and functions but are new, simpler
#implementations. Who, for example, is a shell script, while ps is
#just 163 lines of C code.
#
#Some commands are essentially the same as their UNIX ancestors:
#awk(1), troff(1), and others have been converted to ANSI C and
#extended to handle Unicode, but are still the familiar tools.
#
#Some are entirely new programs for old niches: the shell rc(1), text
#editors acme(1) and sam(1), debuggers acid(1) and db(1), and others
#displace the better-known UNIX tools with similar jobs.
#
#Compatibility was not a requirement for the system. Where the old
#commands or notation seemed good enough, we kept them. When they
#didn't, we replaced them.
#
#The following list of some UNIX commands, files, and shell
#terminology, which you can emulate in a Plan 9 system:
