Re: Editing File In-Place to put tab before UpperCase Letters

Slight mod to avoid leading space and need for capture. Puts a space (" ") instead of a tab. "\b" is not a space but a boundary.

perl -pi -e 's/(?!\A)(?=\p{IsUpper})/ /g'

Putting "\b" in the string would add a backspace, not a word boundary.	[reply]

Er, quite right, of course. I was thinking of the left side. Pattern match--boundary, interpolated string--backspace.	[reply]
