Hi,
Is there any way to find ?
a particular library(".so" file) is used by which executable?

Thanks in advance

Check out the lsof command

Code:

lsof -p <process id>

You can do the reverse: find which executable is using which .so file, if that's any use?...

Code:

ldd /usr/bin/vim

will show you which shared library dependencies vim has.

hi Vikas,
I have checked man page for lsof
But there is no entry for it

hi pwc101,
I have done that, but i am not getting the expected
".so" file. that's why i am thinking in reverse way.

Hi Amrita,

In case u dont have lsof installed, u can go thru the online man page at http://www.die.net/doc/linux/man/man8/lsof.8.html

Notice that when lsof is run without giving any filename it lists all open files belonging to all active processes and u can grep the output to locate the .so file ur looking for

lsof | grep 'xyz.so'

Unless you're running as root, you might not have lsof in your PATH, so might be worth doing a

Code:

locate lsof

and finding the binary. Mine on RHEL4 was /usr/sbin/lsof.

Code:

% for binary in /bin/* /sbin/* /usr/local/bin/* /usr/local/sbin/* /put/other/path/here/bin/* ;do if [ ! $(ldd `which ${binary}` | grep -q libCNTIbbk.bm.so) ]; then echo ${binary} ;fi ;done

to check which binaries use libCNTIbbk.bm.so

Very cunning!

lsof isn't bundled with Solaris.

The "lsof" package can be found on www.sunfreeware.com
