A Few Useful Unix Commands










cat --- for displaying a file
cd --- change directory
cd 1--- to move to sub-directory 1 & so on
cp --- for copying files
ls --- see what files you have
pwd --- find out what directory you are in
rm --- remove a file
pico --- a Unix editor
F77 --- to compile a Fortran programs
To attend a Unix seminar, please contact
assist@mcsr.olemiss.edu
Example of test.f
 c
to run this program on willow enter: f77 test.f, which is the
name of this program. BLUE LINES ARE COMMENTS

x=1.0

w=4.*x

y=2.0

z=x+y
 c
open statement below creates an output file called 'output'.

open(6,file='output')

write(6,100)x,y,z,w
 c
write statement writes the values of x,w,y, and z.
 100 format(2x,4f10.2)

stop
