radare2 looks all fancy and nice, but it is difficult to use with real binaries.
Ever tried to this:
~$ time rabin2 -rs myLargeBinary > rabin_dump.txt real 9m59.718s user 9m58.644s sys 0m0.792s ~$ wc -l rabin_dump.txt 153965 rabin_dump.txt
I tried with a 50MB binary. Takes almost 10 minutes!
Now something similar with readelf:
~$ time readelf -s myLargeBinary > readelf_sym.txt real 0m0.361s user 0m0.292s sys 0m0.064s ~$ wc -l readelf_sym.txt 154573 readelf_sym.txt
How could the difference be so large?
Load the symbols from radare script
r2 -n myLargeBinary [0x00000000]> ?t . rabin_dump_clean.txt 2.279235
