The attr package contains utilities to administer the extended attributes on filesystem objects.

Approximate build time: less than 0.1 SBU
Required disk space: 4.2 MB

8.18.1. Installation of Attr

Prepare Attr for compilation: 

./configure --prefix=/usr     \
            --bindir=/bin     \
            --disable-static  \
            --sysconfdir=/etc \
            --docdir=/usr/share/doc/attr-2.4.48

Compile the package: 

make

The tests need to be run on a filesystem that supports extended attributes such as the ext2, ext3, or ext4 filesystems. To test the results, issue: 

make check

Install the package: 

make install

The shared library needs to be moved to /lib, and as a result the .so file in /usr/lib will need to be recreated: 

mv -v /usr/lib/libattr.so.* /lib
ln -sfv ../../lib/$(readlink /usr/lib/libattr.so) /usr/lib/libattr.so

8.18.2. Contents of Attr
