In Unix, how do I find out which executables or processes are using my shared libraries?

Question

How do I find out which executables or processes are using my shared library objects in a Unix environment, specifically the AIX environment. Is there any command for it?

Answer 1

Not sure if it will help, but maybe you could lsof.

Answer 2

In linux, you would:

for i in /usr/bin /bin /usr/local/bin /sbin /...; do
  # edit: bug fix to display which filename has the library
  # the egrep component will extract line with your library
  # or line with ":::", which contains name of the binary
  find /usr/bin -printf '::: %p\n' -exec ldd \{\} \; | egrep 'your lib. name|:::'
done

The ldd package for AIX can be found as described here

To check running processes, you could: lsof | grep 'your library name'. How to obtain lsof for AIX can be found here

Answer 3

fuser might be what you want.

Answer 4

In Solaris Open or otherwise:

For example; some of the output supressed...
