Before you rm a file, check it with fuser. No output means not in use and safe to delete.
I'm not sure that the code from MadeInGermany does actually do this. To me, it looks like it finds files over 100 blocks (i.e. 100 x 512 bytes = 51,200 bytes) Searching by modification time uses the -mtime flag, more like this:-
Code:
find / -xdev -type f ! -mtime +5
.... to find files that are "not more than five days since last update"
When using fuser, I would caution you that a file not being in use does not necessarily mean that it is safe to delete. If you remove /usr/bin/rm because it's not in use, then you start getting into real trouble. There are many others that you should not delete too. I would add that your should know that you don't need a file before you remove it. Of course, OS critical files should not have been recently updated, so that gives you some protection there.
If there are some large ones that you don't recognise, post a (full path) list of them in CODE tags and we'll see if there is anything standard that you need to keep. Also be aware that database files will always be showing as newly updated. Hopefully, they will show as in-use, but it depends how your applications work.

If we set up FTP only users who can't log in with a shell (/bin/false type of shell) and set them up with a default password, like abc123 or something not secure, is there any way for the user to change their own password once they get on the system? (2 Replies)

find
find(1) General Commands Manual find(1)Name
find - find files
Syntax
find pathname-list expression
Description
The command recursively descends the directory hierarchy for each pathname in the pathname-list (that is, one or more pathnames) seeking
files that match a boolean expression written in the primaries given below. In the descriptions, the argument n is used as a decimal inte-
ger where +n means more than n, -n means less than n , and n means exactly n.
Options-atime n Tests true if the file has been accessed in n days.
-cpio output Writes current file on output in the format (5120-byte records) specified in the reference page. The output can be either a
file or tape device. If output is a tape device the B key must be used to read data from the tape.
-ctime n Tests true if the file has been changed in n days.
-depth Always true; causes descent of the directory hierarchy to be done so that all entries in a directory are acted on before the
directory itself (that is, postorder instead of preorder). This can be useful when is used with to transfer files that are
contained in directories without write permission.
-exec command Tests true if specified command returns a 0 on exit. The end of the command must be punctuated by an escaped semicolon. A
command argument `{}' is replaced by the current pathname.
-group gname Tests true if group ID matches specified group name.
-inum n Tests true if the file has inode number n.
-links n Tests true if the file has n links.
-mount Tests true if the current file is on the same file system as the current starting pathname.
-mtime n Tests true if the file has been modified in n days.
-name filename Tests true if the filename argument matches the current file name. Normal Shell argument syntax may be used if escaped
(watch out for `[', `?' and `*').
-newer file Tests true if the current file has been modified more recently than the argument file.
-ok command Executes specified command on standard output, then standard input is read and command executed only upon response y.
-perm onum Tests true if file has specified octal number. For further information, see If onum is prefixed by a minus sign, more flag
bits (017777) become significant and the flags are compared: (flags&onum)==onum. For further information, see
-print Prints current pathname.
-size n Tests true if the file is n blocks long (512 bytes per block).
-type c Tests true if file is c type ( c = b, block special file: c, character special file: d, directory: f, plain file: l, sym-
bolic link: p, type port: s, type socket).
-user uname Tests true if file owner is login name or numeric user ID.
The primaries may be combined using the following operators (in order of decreasing precedence):
1) A parenthesized group of primaries and operators (parentheses are special to the Shell and must be escaped).
2) The negation of a primary (`!' is the unary not operator).
3) Concatenation of primaries (the and operation is implied by the juxtaposition of two primaries).
4) Alternation of primaries (`-o' is the or operator).
Examples
To remove all files named `a.out' or `*.o' that have not been accessed for a week:
find / ( -name a.out -o -name '*.o' )
-atime +7 -exec rm {} ;
To find all files on the root file system type:
find / -mount -print
To write all the files on the root file system to tape:
find / -mount -print -cpio /dev/rmt?h
cpio -iBvt < /dev/rmt?h
To find all the mount points on the root file system type:
find / ! -mount -print
