NOHUP(1)                                                 NOHUP(1)



     NAME
          nohup - run a command immune to hangups and quits

     SYNOPSIS
          nohup command [ arguments ]

     DESCRIPTION
          nohup 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, output 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
          pipelines 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

     SEE ALSO
          chmod(1), nice(1), sh(1),
          signal(2) in the Programmer's Reference Manual.

     WARNINGS
          In the case of the following command

               nohup command1; command2

          nohup applies only to command1.  The command

               nohup (command1; command2)

          is syntactically incorrect.
