checking the installated program


I am new to linux, I wish to know how to check the installed program in terminal?

I have installed a fortran program through yast, but when I check using “which fortran” command, it shows the error,

linux-blxt:/home/visu # which fortran
which: no fortran in (/usr/lib/mpi/gcc/openmpi/bin:/home/visu/bin:/usr/local/bin:/usr/bin:/sbin:/usr/sbin:/bin:/usr/bin/X11:/usr/X11R6/bin:/usr/games:/usr/lib/mit/bin)

please can any one help me to install the fortran package?

Thanks in advance


The name of the compiler executable is gfortran not fortran, check if
gfortran exists.

terminal command : zypper se fortran

in left hand column of results the i character indicates those installed.
