use "file" command

e.g.

$ ps aux | grep -i firefox
    6363  9.8  7.0 577012 141764 ?       Sl   18:37   0:45
/usr/lib/firefox-3.0/firefox
    6700  0.0  0.0   5164   888 pts/1    R+   18:45   0:00 grep -i firefox

$ file /usr/lib/firefox-3.0/firefox
/usr/lib/firefox-3.0/firefox: ELF 64-bit LSB executable, x86-64, version 1
(SYSV), for GNU/Linux 2.6.8, dynamically linked (uses shared libs), stripped
