NOHUP(1)             INTERACTIVE UNIX System             NOHUP(1)



          NAME
               nohup - run a command immune to hangups and quits

          SYNOPSIS
               nohup command [ arguments ]

          DESCRIPTION
               The nohup command executes command with hangups and quits
               ignored.  If output is not re-directed by the user, both
               standard output and standard error are sent to nohup.out.
               If nohup.out is not writable in the current directory, out-
               put is redirected to $HOME/nohup.out.

          EXAMPLE
               It is frequently desirable to apply nohup to pipelines or
               lists of commands.  This can be done only by placing pipe-
               lines and command lists in a single file, called a shell
               procedure.  One can then issue:

                    nohup sh file

               and the nohup applies to everything in file.  If the shell
               procedure file is to be executed often, then the need to
               type sh can be eliminated by giving file execute permission.
               Add an ampersand and the contents of file are run in the
               background with interrupts also ignored [see sh(1)]:

                    nohup file &

               An example of what the contents of file could be is:

                    sort ofile > nfile

          WARNINGS
               In the case of the following command

                    nohup command1; command2

               nohup applies only to command1.  The command

                    nohup (command1; command2)

               is syntactically incorrect.
