[SunHELP] insert one line at beginning of text file; efficien tly

[sunhelp at sunhelp.org]

Dale if you dont mind if I wanted to pass paramers ($1 $2 .....) to theis
perl
command how can I get it to go through without PERL trying to process the 
variable.  Appears the shell never gets to replace the variable value.

Example:
#! /bin/ksh
 OPTION=$1  # used variable OPTION here because first attempt with $1 didnt
work.
 perl -e 'print "${OPTION}\n"; while(<>){ print;}' < test.tmp > test.new

ouput shows a blank line at the beginning.


Thanks for your time.

perl -e 'print "\n"; while(<>){ print;}' < inputfile > outputfile
