They are designed to be simple to use, have flexible ways to pass in or get the file contents and to be very efficient. There is also a sub to read in all the files in a directory. .SS "\s-1WARNING\s0 \- \s-1PENDING DOOM\s0" .IX Subsection "WARNING - PENDING DOOM" Although you technically \fIcan\fR, do \s-1NOT\s0 use this module to work on file handles, pipes, sockets, standard \s-1IO,\s0 or the \f(CW\*(C`DATA\*(C'\fR handle.

It is a combination of \*(L"read_file\*(R" in File::Slurp and \*(L"write_file\*(R" in File::Slurp. It works by first using \f(CW\*(C`read_file\*(C'\fR to slurp in the file and then calling \&\f(CW\*(C`write_file\*(C'\fR with the new data and the existing file data. .PP The first argument to \f(CW\*(C`prepend_file\*(C'\fR is the filename. .PP The next argument(s) is either a hash reference or a flattened hash, \&\f(CW\*(C`key => value\*(C'\fR pairs.

You can use this option to pass in a scalar reference and the slurped file contents will be stored in the scalar. This saves an extra copy of the slurped file and can lower \s-1RAM\s0 usage vs returning the file. It is usually the fastest way to read a file into a scalar. .IP "\(bu" 4 chomp .Sp The \f(CW\*(C`chomp\*(C'\fR option is a boolean option, defaulted to false (\f(CW0\fR).
