How to check which package’s modules a particular process is using

1. Get PID of process.

ps aux | grep 'process name what you wanna check'

I picked up konsole

2. Check loaded modules by process using PID.

lsof -p 'PID'

Part of modules that konsole is using

3. Search modules by modules full path.

dpkg -S 'Full path of module'

libicudata.so.71.1 is included in libicu71

4. You can check what modules are included in package.

dpkg -L 'pacage name'

Can confirm libicudata.so.71.1 is included
