find the version of gcc g77 in the system

some little things that I used this afternoon.....

In rpm based distribution: (for example mandriva)
rpm -qa | grep gcc

In ubuntu: locate gcc

find ./ -name bash
or, echo $SHELL

For different fortran compilers,

if use the ibm fortran compiler, can try for example
ifort -fast -save file.f
