Explanation from Perl Expert pls ....

[hendnov]

Hi guys,

I've got the perl code, here it is :

find . | perl –ne‘chomp();rename($_,lc($_))’

I know this code is for rename all the file to lower case recursively but could you guys explain exactly what chomp for ? and "$_" means ??

Thx guys

chomp removes newline characters (\n, \r) from the end of the variable (or in array context, the end of each array item). $_ is a default Perl variable for the current item in a loop.
