Say I wanted to a string replace on a file with the following contents
name
nAmE
naMEbb
NAME
And wanted to replace the word "name" with "dave", but keeping the capitalization of the original text. For example, my desired output would be,
dave
dAvE
daVEbb
DAVE
Are there any one-liners to do this (preferably in Perl so I can do an in-place substitution across many files)?
EDIT The problem is ambiguous unless both strings have exactly the same length. Let's assume it does.
