Hi,
I’d like to write a shell script to copy a collection of the last
available shared libs but I don’t want to modify this script anytime.
I 'd like to make copy of my_lib.so.1.0 based on my_lib.so.

I didn’t see any command to get that info except ‘ls -l’ which would
need to use the powerfull/incomprehensible sed command.
I could write an exe and use readlink() but I’m very surprised that no
cmd or option exists to get it in a readable way.

Any idea?

Thanks,
Alain.

I’m not exactly sure what you want, but would some mix of:
ls | sort | uniq
give you what you want?

find my_lib.so -printf “%l\n”

Not to say that find isn’t also powerful/incomprehensible :slight_smile:.
