It's a pre-defined alias in ksh where the entire POSIX history scheme is taken from. Roughly, it's the equivalent to the csh '!' history substitution, although less powerful. Use "r" to repeat the last command, "r cmd" to repeat the last command "cmd", and "r foo=bar ..." to effect a substitution on the recalled command line. -- Christian "naddy" Weisgerber naddy@mips.rhein-neckar.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
