Shell Programming and Scripting

I had to whip this up, and it seems useful enough to post here. Say you have been cleaning up your filesystem, and you removed a bunch of libraries, or you shuffled around some library directories, and aren't sure if ld.so.conf is correctly setup. You want to sweep through your file system looking for executables that cannot run because their libraries are now missing. Here's a really simple script to do just that:

Code:

find / -type f -exec file "{}" ";" | 
    awk '/dynamically linked/ { print $1 }' |
    sed 's/:$//' | 
    xargs ldd | 
    awk 'NF==1 {file=$1} /not found/ { print file, $1 }'

You might want to direct output to "tee" or perhaps just a file.

I only work with Linux these days. If you work with another OS and this script needs a tweak to work on it, please post a follow-up.
