| 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. They also |
|---|
| 3 | support some additional options, some borrowed from Unix and some |
|---|
| 4 | unique to GNU. |
|---|
| 5 | |
|---|
| 6 | See the file NEWS for a list of major changes in the current release. |
|---|
| 7 | |
|---|
| 8 | See the file INSTALL for compilation and installation instructions. |

|---|
| 10 | Special configure options: |
|---|
| 11 | |
|---|
| 12 | --with-afs |
|---|
| 13 | Make find support "-fstype afs". Requires /afs, /usr/afsws/lib, and |
|---|
| 14 | /usr/afsws/include. configure doesn't add AFS support |
|---|
| 15 | automatically because it adds considerably to find's size, and the |
|---|
| 16 | AFS libraries need -lucb on Solaris, which breaks find. |
|---|
| 17 | |
|---|
| 18 | --enable-id-cache |
|---|
| 19 | Make tables of used UIDs and GIDs at startup instead of using |
|---|
| 20 | getpwuid or getgrgid when needed. Speeds up -nouser and -nogroup |
|---|
| 21 | unless you are running NIS or Hesiod, which make password and group |
|---|
| 22 | calls very expensive. |
|---|
| 23 | |
|---|
| 24 | To gain speed, GNU find avoids statting files whenever possible. |
|---|
| 25 | It does this by: |
|---|
| 26 | 1. Checking the number of links to directories and not statting files |
|---|
| 27 | that it knows aren't directories until it encounters a test or action |
|---|
| 28 | that needs the stat info. |
|---|
| 29 | 2. Rearranging the command line, where possible, so that it can do tests |
|---|
| 30 | that don't require a stat before tests that do, in hopes that the |
|---|
| 31 | latter will be skipped because of an OR or AND. (But it only does |
|---|
| 32 | this where it will leave the output unchanged.) |
|---|
| 33 | |
|---|
| 34 | The locate program and its helper programs are derived (heavily |
|---|
| 35 | modified) from James Woods' public domain fast-find code, which is |
|---|
| 36 | also distributed with the 4.3BSD find. Because POSIX.2 requires `find |
|---|
| 37 | foo' to have the same effect as `find foo -print', the fast-find |
|---|
| 38 | searching has been moved to a separate program, `locate'; the same |
|---|
| 39 | thing has been done in 4.4BSD. If you use locate, you should run the |
|---|
| 40 | included `updatedb' script from cron periodically (typically nightly). |
|---|
| 41 | |
|---|
| 42 | The `Makefile.am' files are used by an experimental program called |
|---|
| 43 | AutoMake that is under development. It's not ready for general use |
|---|
| 44 | yet, so don't worry about them. |
|---|
| 45 | |
|---|
| 46 | Mail suggestions and bug reports for these programs to |
|---|
| 47 | bug-findutils@gnu.org. |
