is there a standalone sed-like tool than can load whole file into memory, perform multiline regex on it and stdout it?

Question

I know I can use any of the scripting languages for it that is perl, python etc... but this means that I must install big package with all its dependencies while I need only regex feature and second I want it to be fast and portable, that is only regex engine and sdt streams compiled into the application, nothing more. Is there anything like it ?

Answer 1

Yes, there is program that does exactly what I was looking for:

https://sites.google.com/site/regexreplace/ - rxrepl, Regular Expression Search and Replace Command Line Tool, Version 1.3

Answer 2

How about using:

• Sed for Windows part of the GnuWin package
• or UnxUtils which also includes Sed

Both are light and fast. Both have dependencies but light ones.

Answer 3

vbscript and powershell have native regex function and is part of windows dependeing version of it.

Answer 4

but this means that I must install big package with all its dependencies
