| 1 | This package contains the GNU find, xargs, and locate programs. find
|
|---|
| 2 | and xargs comply with POSIX 1003.2, as far as I know (with the
|
|---|
| 3 | exception of the "+" modifier for the "-exec" action, which isn't
|
|---|
| 4 | implemented yet). They also support a large number of additional
|
|---|
| 5 | options, some borrowed from Unix and some unique to GNU.
|

|

| 11 | To verify the GPG signature of the release, you will need the public
|
|---|
| 12 | key of the findutils maintainer. You can download this from
|
|---|
| 13 | ftp://ftp.gnu.org/gnu/gnu-keyring.gpg. Alternatively, you could query
|
|---|
| 14 | a PGP keyserver, but you will need to use one that can cope with
|
|---|
| 15 | subkeys containing photos. Many older key servers cannot do this. I
|
|---|
| 16 | use subkeys.pgp.net. I think that one works. See also the
|
|---|
| 17 | "Downloading" section of http://www.gnu.org/software/findutils/.
|

|
|---|
| 19 | Special configure options:
|
|---|
| 20 |
|
|---|
| 21 | --with-afs
|
|---|
| 22 | Make find support "-fstype afs". Requires /afs, /usr/afsws/lib, and
|
|---|
| 23 | /usr/afsws/include. configure doesn't add AFS support
|
|---|
| 24 | automatically because it adds considerably to find's size, and the
|
|---|
| 25 | AFS libraries need -lucb on Solaris, which breaks find.
|
|---|
| 26 |
|
|---|
| 27 | --enable-id-cache
|
|---|
| 28 | Make tables of used UIDs and GIDs at startup instead of using
|
|---|
| 29 | getpwuid or getgrgid when needed. Speeds up -nouser and -nogroup
|
|---|
| 30 | unless you are running NIS or Hesiod, which make password and group
|
|---|
| 31 | calls very expensive.
|
|---|
| 32 |
|
|---|
| 33 | --enable-debug
|
|---|
| 34 | Produce output on the standard error output indicating what find is
|
|---|
| 35 | doing. This information includes details about how the command line
|
|---|
| 36 | has been parsed and what files have been stat()ed. This output is
|
|---|
| 37 | normally interesting only to the maintainer, and so is off by default.
|
|---|
| 38 |
|
|---|
| 39 |
|
|---|
| 40 | To gain speed, GNU find avoids statting files whenever possible.
|
|---|
| 41 | It does this by:
|
|---|
| 42 | 1. Checking the number of links to directories and not statting files
|
|---|
| 43 | that it knows aren't directories until it encounters a test or action
|
|---|
| 44 | that needs the stat info.
|
|---|
| 45 | 2. Rearranging the command line, where possible, so that it can do tests
|
|---|
| 46 | that don't require a stat before tests that do, in hopes that the
|
|---|
| 47 | latter will be skipped because of an OR or AND. (But it only does
|
|---|
| 48 | this where it will leave the output unchanged.)
|
|---|
| 49 |
|
|---|
| 50 | The locate program and its helper programs are derived (heavily
|
|---|
| 51 | modified) from James Woods' public domain fast-find code, which is
|
|---|
| 52 | also distributed with the 4.3BSD find. Because POSIX.2 requires `find
|
|---|
| 53 | foo' to have the same effect as `find foo -print', the fast-find
|
|---|
| 54 | searching has been moved to a separate program, `locate'; the same
|
|---|
| 55 | thing has been done in 4.4BSD. If you use locate, you should run the
|
|---|
| 56 | included `updatedb' script from cron periodically (typically nightly).
|
|---|
