Full Discussion: Repeat output of last command w/o repeating last command
Top Forums UNIX for Advanced & Expert Users Repeat output of last command w/o repeating last command Post 302388736 by pludi on Thursday 21st of January 2010 09:04:07 AM

Not quite, bash and ksh aliases won't accept parameters. But that's what functions are for:
Code:
function cache {
    exec 3>&1
    ( "$@" | tee ."$( basename $1 )".out >&3 ) 2>&1 | \
        tee ."$( basename $1 )".err >&2 3>&1
    3>&-
}

This'll redirect regular output to one file (eg. .ls.out if you cache ls), and stderr to another (eg. .ls.err), while leaving the regular output unaffected (stdout and stderr can be filtered just the same as always).

Redirection to the third channel blatantly stolen from Csh Programming Considered Harmful, as I can never remember the exact syntax.

basename

basename(1B)					     SunOS/BSD Compatibility Package Commands					      basename(1B)

NAME

       basename - display portions of pathnames

SYNOPSIS

       /usr/ucb/basename string [suffix]

DESCRIPTION

       The  basename  utility deletes any prefix ending in `/' and the suffix, if present in string. It directs the result to the standard output,
       and is normally used inside substitution marks (` `) within shell procedures. The suffix is a string with no special significance  attached
       to any of the characters it contains.

EXAMPLES

       Example 1 Using the basename command.

       This shell procedure invoked with the argument /usr/src/bin/cat.c compiles the named file and moves the output to cat in the current direc-
       tory:

	 example% cc $1
	 example% mv a.out `basename $1 .c`
