A Perl enthusiast, I earn my living doing Unix/Linux system administration and light systems programming. In a former life I was an ALGOL systems programmer before finding my real love was for Unix. My education is scientific with a Master of Science degree.

comment What's the difference between a hard links and copied files?
@EmanuelBerg Create a simple shell script that echos $0 (the name by which it is run). Now create one or more links to the script. Run the script with its original name and by invoking the link. The lesson should be obvious, then.

comment What's the difference between a hard links and copied files?
@EmanuelBerg My point was that regardless of whether hard or soft links are used, it's the name by which the executable is invoked that determines the options and arguments that are valid for execution.
