It now enforces the previously voluntary restriction of running one such command at a time. Now, you can safely run a second command some time after the first; if the first has not finished, "nohup" will complain and refuse to run the second. The correct method for running a command in the background remains: % nohup ms -p lpr file1 file2 & where "nohup" and "&" are obligatory and the "ms -p lpr file1 file2" could be any normal command. The ampersand (&) must NEVER be used without "nohup". -- David Trueman @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!david
