A coworker somehow got the shell to do looping without creating a file. I believe he was using csh to do so and I was wondering if I could do the same thing in bash. Basically I would like to be able to do a while loop to execute a df command. Any ideas? </pre> </blockquote> <pre wrap=""> almost any shell command sequence can be executed on the command line... consider the following.. while true; do df; sleep 3; done; just a matter of separating the command elements with ;'s </pre> <blockquote type="cite"> <pre wrap="">-- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. -- fedora-list mailing list <a class="moz-txt-link-abbreviated" href="mailto:fedora-list@redhat.com">fedora-list@redhat.com</a> To unsubscribe: <a class="moz-txt-link-freetext" href="https://www.redhat.com/mailman/listinfo/fedora-list">https://www.redhat.com/mailman/listinfo/fedora-list</a> </pre> </blockquote> <pre wrap=""> </pre> </blockquote> Actually, if you just want to loop some command, you can use the command watch as well. Like so: watch -n3 df Saves writing/typing bash-scripts :) </body> </html>
