Get the filename linked to symbolic link
Hello guys,
I have a simple problem. Do you know any way to get the get the filename linked to symbolic link? I think use "ls -l <myfile> | cut -d '>' -f2", but i know it is a bad practice take information from the output of "ls -l". I dont have "stat" comand neither.
Regards!
Example:
I have this symbolic link:
lrwxrwxrwx 1 USER.SUPER USER 21 Jul 26 2013 mylink.so -> myLibrary.so
And i want to get only this "myLibrary.so" and save it in a variable of a script.
