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.
