Be careful when using LDD. It will expand the libraries as in the following
example:
ldd /bin/ls
linux-hellokitty.so.1 (0x00007ffec5daa000)
libcap.so.2 => /lib/libcap.so.2 (0x00007f1d2822d000)
libacl.so.1 => /lib/libacl.so.1 (0x00007f1d28025000)
libc.so.6 => /lib/libc.so.6 (0x00007f1d27c57000)
libattr.so.1 => /lib/libattr.so.1 (0x00007f1d27a53000)
/lib64/ld-linux-x86-64.so.2 (0x00007f1d28431000)
readelf -d /bin/ls | grep NEEDED
0x0000000000000001 (NEEDED) Shared library: [libcap.so.2]
0x0000000000000001 (NEEDED) Shared library: [libacl.so.1]
0x0000000000000001 (NEEDED) Shared library: [libc.so.6]
Because libacl and libcap needs libattr, ldd will expose that.
Use the following script which Armin provided a long time ago:
#!/bin/sh
if [ ! $1 ]; then
/bin/echo -e "this script requires one arguments."
exit 1
fi
rm -f ${PWD}/check
find {,/usr}/{bin,lib,sbin} -type f ! -path "*/debug/*" ! -path "*/java/*" !
-path "*/syslinux/*" ! -path "*/vmware*/*" 2>/dev/null | while read
BUILD_BINARY ; do
case "$(file -bi "${BUILD_BINARY}")" in
*application/x-sharedlib* | *application/x-executable*)
readelf -d ${BUILD_BINARY} | grep "NEEDED" | grep $1 > /dev/null
if [ $? -eq 0 ]; then
/bin/echo ${BUILD_BINARY} >> ${PWD}/check
fi
esac
done
