NAME

	9 – run Plan 9 commands

SYNOPSIS

	9 cmd [ args ... ] . 9

DESCRIPTION

Because Plan 9 supplies commands with the same name as but different behavior than many basic Unix system commands (e.g., grep, sed, mkdir, rm), it is not recommended to run with the Plan 9 bin directory ahead of the system directories. 9 is a shell script that sets up a Plan 9 environment and runs cmd . It sets $PLAN9 and adds $PLAN9/bin to the beginning of $PATH before running cmd. If run with no arguments, 9 does not do anything. This is so that it can be invoked from sh-style shells using . 9 in order to make the current shell start running in the Plan 9 environment.

EXAMPLES

	Search for greek in the password file: $ 9 grep '[α−ζ]' /etc/passwd Start an rc(1) with the Plan 9 commands in the path before the system commands. 9 rc
