Presentation Transcript

  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 don’t 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 < inputFile > 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 < inputFile > outputFile

  5. Tips and Warnings • Not all CSP machines are created equal • I’ll 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
