NAME

s2p - Sed to Perl translator  

SYNOPSIS

s2p [options] filename  

DESCRIPTION

S2p takes a sed script specified on the command line (or from standard input) and produces a comparable perl script on the standard output.  

Options

Options include:
-D<number>
sets debugging flags.
-n
specifies that this sed script was always invoked with a sed -n. Otherwise a switch parser is prepended to the front of the script.
-p
specifies that this sed script was never invoked with a sed -n. Otherwise a switch parser is prepended to the front of the script.
 

Considerations

The perl script produced looks very sed-ish, and there may very well be better ways to express what you want to do in perl. For instance, s2p does not make any use of the split operator, but you might want to.

The perl script you end up with may be either faster or slower than the original sed script. If you're only interested in speed you'll just have to try it both ways. Of course, if you want to do something sed doesn't do, you have no choice. It's often possible to speed up the perl script by various methods, such as deleting all references to $\ and chop.  

ENVIRONMENT

S2p uses no environment variables.
