S2P(1) Perl Programmers Reference Guide S2P(1)NAMEs2p - Sed to Perl translator
SYNOPSISs2p [options] filename
DESCRIPTIONs2p 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.
ENVIRONMENTs2p uses no environment variables.
