index.ksh:

Code:
#!/bin/ksh

date
timex cp -pr /copy/index /db/devdb
date

Then I created a script called x.ksh as below:

Code:
#!/bin/ksh
nohup data.ksh  & 1>data.ksh.out  2>&1
nohup index.ksh & 1>index.ksh.out 2>&1

Then I run x.ksh
I am hoping to get some output from the .out file but I got nothing

I tried running the nohup manually from the command line. Same result, i.e. blank .out files.

Or do I simply have the first & in the wrong place Smilie
As I said before; you simply have every redirection and the ampersand in the wrong place. Try:
Code:
#!/bin/ksh
nohup data.ksh 2>&1 >data.ksh.out&
nohup index.ksh 2>&1 >index.ksh.out&

First, redirect the standard error output from the script to the same file descriptor that gets standard output from the script (2>&1). Then redirect the standard output from the script to a file for that script (>filename). Then run the command in the background (&).

NOHUP(1)                                                           User Commands                                                          NOHUP(1)

NAME
nohup - run a command immune to hangups, with output to a non-tty SYNOPSIS
nohup COMMAND [ARG]... nohup OPTION DESCRIPTION
Run COMMAND, ignoring hangup signals. --help display this help and exit --version output version information and exit If standard input is a terminal, redirect it from an unreadable file. If standard output is a terminal, append output to 'nohup.out' if possible, '$HOME/nohup.out' otherwise. If standard error is a terminal, redirect it to standard output. To save output to FILE, use 'nohup COMMAND > FILE'. NOTE: your shell may have its own version of nohup, which usually supersedes the version described here. Please refer to your shell's doc- umentation for details about the options it supports. AUTHOR
