linux tool to list all functions in a source file?

+5 A:

ctags can give you that (and much more). It is included with most Linux distributions...

i know about ctags, but it generates its tags file, which then is needed to be imported to an editor e.g. vim. I was asking for a simple utility, that just prints the function names on console, if ctags does that I am not sure

then you want `ctags -x`, which prints a human readable summary of stuff.

Also `ctags -f -` prints the output to stdout, and not a tag file. You can then use `awk` or something similar...

A:

It is not clear which language you refer to: if:

complied elf file then you have readelf utility providing that you compiled file with debug information "-g"

This won't work for C++, due to name-mangling...

@Gilad Naor - But you can then use c++filt to demangle them

Not sure if it would be useful for your exact purpose, but take a look at GCC-XML

You can try Doxygen http://www.stack.nl/~dimitri/doxygen/

You might also want to take a look at cscope which is similar to ctags suggested in the accepted answer. It creates its own symbol database. It provides a nice interface for you, enabling search of a given symbol/inclusion/file/declaration within your project.
