How to find all packes using a shared lib?

[tinkertim]

Hello,

I am about to make some changes to libreadline and libedit (aka libeditline), I need to try to find all installed packages that are dynamically linked against either library.

Is there some way I can use dpkg to find what installed programs depend on either library?

Thanks in advance :)

I don't know how to limit this to just installed programs though :(

EDIT:

for what you want use:


apt-cache --installed rdepends libreadline5
AND

apt-cache --installed rdepends libeditline0

[iaculallad]

Try using the ldd terminal command:

The example below will list (verbose) all shared libraries being used by the gedit application.

*Just be sure that you're in the /usr/bin directory when executing this command.


ldd -v gedit

or


ldd -v /usr/bin/gedit

ldd -v gedit

or


ldd -v /usr/bin/gedit

ldd gives me great info if I want to build a chroot. In fact, it also helps determine programs that were compiled with bloated shared dependencies.

Unfortunately, it doesn't tell me every installed program on the system that depends on some shared lib. :(

I'm going to be hacking at a few (readline being one) and I'm hoping to find out what I might break. I've done testing in /usr/local/lib, now its time to see what shatters :)

apt-cache --installed rdepends libreadline5

apt-cache --installed rdepends libeditline0

That worked!! Thank you scragar :) I really needed to see what I (might) break when testing in production.

I also need to say, this forum is the best :) I've been using Ubuntu since its first release .. when my day job is not so taxing I hope to answer more questions than I ask.
