req: New feature to rm? Remove file by the inode number
I couldn't find a way to remove files that had scandic/non-printable letters, then i remembered ls showed inode number of the file. Is it possible to remove the file by the inode number? It would be a useful feature :) I bet there is a way to remove those files, but only third party programs came to my mind.

Re: req: New feature to rm? Remove file by the inode number
A couple of observations: 1) Implicit in most people's answers is the fact that a single inode can have many directory entries. That's why find is used. That's also why the solution below won't work, as it doesn't check the entire file system (nor would you want to answer y/n for all those files :) 2) The same inode number can exist for multiple files in a system. This occurs if multiple file systems exist. So, if you use find to achieve the desired effect, be very sure that you run it from the root of the target file system and that you tell it not to traverse onto other file systems. If you run it from the root directory, you're very likely to delete one or more files you didn't mean to delete. Point 2, likely as not, might explain why there's no simple mechanism for doing this from rm. At the very least you'd have to specify the file system you're referring to, and many plain users couldn't do that safely. Those that can are probably able to use find anyway.

The POSIX std requires -i to be used for 'interactive'

most unix systems).

The POSIX std requires -i to be used for 'interactive' (and even if it didn't that is already the case on most unix systems). That's exactly the way I meant this to be used... if you use the command rm -i ./* you will be asked for each file whether you want to remove it (except for files beginning with ., of course). I don't see this as more cumbersome than using ls -i to get a list of inodes, and then using clri or whatever to remove the inode; which operation is probably the wrong solution anyway, as there may be other directory entries that point to the same inode, and which should be allowed to do so even after the unwanted directory entries have been removed. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: req: New feature to rm? Remove file by the inode number
My point of view is if you add inode removing option to the rm
you'll have to add en extra parameter, that is on which *filesystem*.
For example, rm -x 2 /var, i am supposing -x as the option for removing
inodes is removing inode number 2 on file system /var
So the pattern seems to be a little confusing since, at a first glance, it
looks like you are removing /var directory. Some dummy users may or
may not be confused.
Because of general purpose of rm is basically removing directory entries,
Adding an extra inode option and specifying a pattern as above is a little
misaiming of rm. No necessasity.
We'd better let third programs achieve such a will. clri and find will be
sufficient.
Sincerely.
P.S: What i've written above is not related to the replied message. I only
replied to be in the thread.

Is it possible to remove the file by the inode number? It would be a useful feature :) It would be a bad feature, at least for the problem you are trying to solve. You are trying to remove one specific filename from one specific directory. It is possible to link multiple filenames to the exact same file (inode). If a file has multiple links to it, then you would want to remove only the filename you're looking at, and not all filenames in the filesystem which might have the same inode. Other solutions, with 'find' or 'rm -i ./*', are more correct for the situation you are looking at. Note that if a file only has *some* unprintable characters, and also has some standard characters, then you can use pattern-matching to reduce how many fines would be matched by 'rm -i'. Something like: rm -i ./*blah* I have been in similar situations to what you're describing, and I've never had to do more than pick a reasonable filename pattern and combine it with -i (-i for interactive, so it prompts you for each file before removing it). -- Garance Alistair Drosehn= [EMAIL PROTECTED] Senior Systems Programmer or [EMAIL PROTECTED] Rensselaer Polytechnic Instituteor [EMAIL PROTECTED] ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

Please make that:
find [...] -print0 | xargs -0 rm
otherwise whitespace characters can cause problems... of course find
does have the -delete option which makes such mangling unnecessary..
