What is difference among 'which' 'Whereis' N 'find' commands?
instead of using 'whereis' by itself, try to use it with '-l' option whereis -l signal.h whereis -l ls whereis -l whereis this has great educational value. 'which' on the other hand can locate only executables which show up in PATH environment variable. as to find. find is a fully generic search utility for all types of device files. find is a proper superset of 'which', 'whereis' find becomes a 'which' when files are searched with -exec, -execdir options. find is a multi-faceted utility and one can make power use of it together with xargs while discounting the shell. warm regards Saifi.
