Regex/Grep and wildcards

John123 · 04-12-2014, 09:26 AM

Hi All,

Stupid newbie question number ... eh? ... whatever.

Using Regex in Sigil I can find (\d+) I would usually put $1 to replace the number it found. This works in Grep but not in Regex?

Are Grep and Regex in any way different?

Please be gentle once you have picked yourself off the floor.

Cheers,

John.

Instead of $1 use \1. That is the normal RegEx way.

Thanks! New it had to be simple, but couldn't find it in the plethora of other information.
