nohup(1)                 USER COMMANDS                   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 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

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

NOTES
     In the case of the following command

          nohup command1; command2

     nohup applies only to command1.  The command

          nohup (command1; command2)

     is syntactically incorrect.
