get rid of a link. This is really stupid. How can a beginner be expected to guess that rm is the way to get rid of a link?
A link is a file. You use rm to remove a file. The deductive leap isn't that large
Say Anders...: How do I get rid of a member of a partitioned data set on my IBM 370 under MVS?
Having never worked directly with MVS I wouldn't know. I do know that IBM is pretty good with its interfaces, so it's probably a menu option. i vaguely remember seeing something in a roscoe menu, but it was too long ago, I can't be certain. If MVS commands anything like OS/400 it's probably something like wrkprtdtaset from the command prompt :)
Get my point?
Not really. Did you get mine?
If the manual tells you that a symlink is just another file, and the section on files tells you that you remove files using 'rm', is it really necessary to repeat that piece of information in the section on symlinks? Are cross-references pedagogically bad?
The point was that in a totally new computing environment it can be a big challange to figure out which is the proper manual to read let alone be able to draw inferances. (A PDS is something so basic to MVS that it is documented (extensivly) in some obscure manual which you may or may not have, but i've never seen it on any menu. The OP was obviously from a windows environment where Bill Gates just "invented" links last year, and therefore they can be quite mysterious. And thinking of a link as a file is NOT correct. Its just another pointer to a file, essentially another directory entry pointing to the file, and it acts quite differently than the actual file. (You can change permissions on a symbolic link till you are blue in the face and still achieve the desired results.) RMing the link may, or may not, remove the file, etc. The man pages for link, symlink, and ln, all sort of gloss over the removal aspect. In short it seems obvious to you and I, but its not unreasonable for a new linux user to be confused about this point. -- _________________________________________________ John Andersen / Juneau Alaska
