.Dd July 19, 2001 .Dt NOHUP 1 .Os .Sh NAME .Nm nohup .Nd invoke a utility immune to hangups .Sh SYNOPSIS .Nm .Op Fl Fl .Ar utility .Op Ar arguments .Sh DESCRIPTION The .Nm utility invokes .Ar utility with its .Ar arguments and at this time sets the signal .Dv SIGHUP to be ignored. If the standard output is a terminal, the standard output is appended to the file
a nohup.out in the current directory. If standard error is a terminal, it is directed to the same place as the standard output.
p Some shells may provide a builtin .Nm command which is similar or identical to this utility. Consult the .Xr builtin 1 manual page. .Sh ENVIRONMENT The following variables are utilized by .Nm : l -tag -width flag t Ev HOME If the output file
a nohup.out cannot be created in the current directory, the .Nm utility uses the directory named by .Ev HOME to create the file. t Ev PATH Used to locate the requested .Ar utility if the name contains no .Ql / characters. .El .Sh EXIT STATUS The .Nm utility exits with one of the following values: l -tag -width Ds t 126 The .Ar utility was found, but could not be invoked. t 127 The .Ar utility could not be found or an error occurred in .Nm . .El
p Otherwise, the exit status of .Nm will be that of .Ar utility . .Sh SEE ALSO .Xr builtin 1 , .Xr csh 1 , .Xr signal 3 .Sh STANDARDS The .Nm utility is expected to be .St -p1003.2 compatible. .Sh BUGS Two or more instances of .Nm can append to the same file, which makes for a confusing output.
