Running Programs on CSP

1
Running Programs on CSP

• CSP01.csci.unt.edu CSP09.
• Secure shell (ssh) to CSP computer
• Transfer file(s) using scp,
• Edit on CSP machine with vi, pico, joe ?
• Compile program
• Run program possibly with redirected input and
  output

2
SSH

• Might be called something else on your computer,
  typically putty
• IFF you dont have ssh, public domain copies are
  available, again likely as putty
• ssh csp04.csci.unt.edu

3
Compile and Run C

• gcc program.c
• ./a.out OR
• gcc -o pgm -O3 program.c -lm
• ./pgm
• Redirection of stdin, stdout
• gcc lt inputFile gt outputFile
• For C, just use g rather than gcc

4
Compile and Run Java

• javc className.java followed by
• java className
• The FileName.java needs to be the same name as
  the name of the class defined IN the file.
• Again, redirection is ok
• java className lt inputFile gt outputFile

Tips and Warnings

• Not all CSP machines are created equal
• Ill use lots of programs in class. They will
  all be found (on a CSP machine) at
• sweany/public/1040/
• sweany and /home/sweany are NOT the same !!!
• sweany is NOT a web site
• cd sweany/public/1040 moves to that directory
