6.39. Findutils-4.4.2

The Findutils package contains programs to find files. These programs are provided to recursively search through

a directory tree and to create, maintain, and search a database (often faster than the recursive find, but unreliable if

the database has not been recently updated).

Approximate build time: 0.5 SBU

Required disk space: 22 MB

6.39.1. Installation of Findutils

Prepare Findutils for compilation:

./configure --prefix=/usr --libexecdir=/usr/lib/findutils \

--localstatedir=/var/lib/locate

The meaning of the configure options:

--localstatedir

This option changes the location of the locate database to be in /var/lib/locate, which is FHS-compliant.

Compile the package:

make

To test the results, issue:

make check

Install the package:

make install

Some of the scripts in the LFS-Bootscripts package depend on find. As /usr may not be available during the early

stages of booting, this program needs to be on the root partition. The updatedb script also needs to be modified to

correct an explicit path:

mv -v /usr/bin/find /bin

sed -i 's/find:=${BINDIR}/find:=\/bin/' /usr/bin/updatedb

6.39.2. Contents of Findutils

Installed programs: bigram, code, find, frcode, locate, oldfind, updatedb, and xargs

Installed directory: /usr/lib/findutils

Short Descriptions

bigram Was formerly used to produce locate databases

code Was formerly used to produce locate databases; it is the ancestor of frcode.

find Searches given directory trees for files matching the specified criteria

frcode Is called by updatedb to compress the list of file names; it uses front-compression, reducing the

database size by a factor of four to five.
