Re: sed command with variable in perl

in reply to sed command with variable in perl

Short version (it's all I have time for): don't. Use regexen. When you're using perl, shelling out is an expensive and unnecessary option in most cases.

It looks as tho you should read about regexen -- and specifically, substitution -- in a tutorial right here; that is, in the Tutorials section.

I did not recognize he word 'regexen' as simply the plural of 'regex'. A search revealed that it is a correct, possibly even preferred, form. An explanation (or reference) would have been a big help. Bill	[reply]
