[linux] How do I view the list of functions a Linux shared library is exporting?

I want to view the exported functions of a shared library on Linux.

What command allows me to do this?

(On Windows I use the program depends)

objdump -T *.so may also do the job

On a MAC, you need to use nm *.o | c++filt, as there is no -C option in nm.

Among other already mentioned tools you can use also readelf (manual). It is similar to objdump but goes more into detail. See this for the difference explanation.

$ readelf -sW /lib/liblzma.so.5 |head -n10
