Quote:
1. "\(.\).*") != '/'
It does not conform with a known regular expression.
I don't know what it means.
Quote:
2. sed 's+^\./++;s+/.*++'
The above 'sed' has two replacement commands:
a) s+^\./++
Removes './' from the beginning of each line/string.

b) s+/.*++
Removes anything that starts with '/' from each line/string.
Quote:
3. sed "s+${f}/+ +
You are missing a double quote (") at the end -- it should be:
sed "s+${f}/+ +"
It replaces the content of variable 'f' followed by one '/' with one space.

ppi::token::quotelike5.18

PPI::Token::QuoteLike(3)				User Contributed Perl Documentation				  PPI::Token::QuoteLike(3)

NAME

       PPI::Token::QuoteLike - Quote-like operator abstract base class

INHERITANCE

	 PPI::Token::QuoteLike
	 isa PPI::Token
	     isa PPI::Element

DESCRIPTION

       The "PPI::Token::QuoteLike" class is never instantiated, and simply provides a common abstract base class for the five quote-like operator
       classes. In PPI, a "quote-like" is the set of quote-like things that exclude the string quotes and regular expressions.

       The subclasses of "PPI::Token::QuoteLike" are:

       qw{} - PPI::Token::QuoteLike::Words
       `` - PPI::Token::QuoteLike::Backtick
       qx{} - PPI::Token::QuoteLike::Command
       qr// - PPI::Token::QuoteLike::Regexp
       <FOO> - PPI::Token::QuoteLike::Readline

       The names are hopefully obvious enough not to have to explain what each class is. See their pages for more details.

       You may note that the backtick and command quote-like are treated separately, even though they do the same thing. This is intentional, as
       the inherit from and are processed by two different parts of the PPI's quote engine.
