OS Differences

Different operating systems handles text files slightly – but in some cases significantly – different.

It may become critical when developing scripts on one platform (e.g. PHP, on Mac) and uploads to a web server running Linux. What works (executes properly) on one platform fails on another.

What differs is how end of line is indicated, what character(s) is/are used – Linefeed (LF, Carriage Return (CR), or both.

Linux/*NIX LF
Mac CR
Windows CRLF
