I've found it kind of complicated to strip newline chars from a file with just the commandline. This tiny piece of code does just that.

I've found it especially useful when extracting tabulated data from a grabbed site where each cell is on a different html line. This way I can pre-filter the html, remove the newlines, and insert them again at register boundaries (row end in this case), so that with just a couple more replacement from within a regex enabled text editor I can copy&paste it directly to a database.

Find File

Open a File For Input

this function returns the aggregated size
of all files in a directory and its subdirectories

Retrieve information about a file

Check the attributes of a file or folde

This function loads an File into an String.

This function tries to locate a file in a give folder (either single level, or in any sub folder). Returns the relative file and path, or FALSE if not found. Skips over "." and "..".

This perl function will output to a file of your choosing the current localtime as defined by perl's localtime function. It will output the date in ISO 8601 date format plus the current localtime such as:
2006-08-21 09:26:35 am
The function also returns the localtime without the date to the calling environment.

Usage:
found('asdf',@array);

P.S. In perl 5.10 can be written as
use 5.010;
'asdf'~~@array;
