Problem Start Shell in background

cocoluigi — Fri, 19 Oct 2007 06:24:46 GMT

Hello..
when I start a shell in background ex:
nohup myshell.sh &
return
[1] + Stopped (tty output) nohup myshell.sh &
more nohup.out
Not a terminal

this is my .profile

# @(#)B.11.11_LR
# Default user .profile file (/usr/bin/sh initialization).

# Set up the terminal:
if [ "$TERM" = "" ]
then
eval ` tset -s -Q -m ':?hp' `
else
eval ` tset -s -Q `
fi
stty erase "^H" kill "^U" intr "^C" eof "^D"
stty hupcl ixon ixoff
tabs

# Set up the search paths:
PATH=$PATH:.

# Set up the shell environment:
set -u
trap "echo 'logout'" 0

# Set up the shell variables:
EDITOR=vi
export EDITOR

How can I solve this problem
Thanks in winter!!!

Why are you showing us your .profile? I think we would be more interested in the contents of myshell.sh

this is content of myshell.sh

. $HOME/.profile
sqlplus -S user/user <spool query.log
@/export/home/oracle/query.sql
spool off

(I won't comment on the sense of sourcing a .profile in a non-interactive script)

Then the problem is the tset commands in your .profile

Chnage your .profile to look like this:

# @(#)B.11.11_LR
# Default user .profile file (/usr/bin/sh initialization).

if /usr/bin/tty -s
then
# Set up the terminal:
if [ "$TERM" = "" ]
then
eval ` tset -s -Q -m ':?hp' `
else
eval ` tset -s -Q `
fi
stty erase "^H" kill "^U" intr "^C" eof "^D"
stty hupcl ixon ixoff
tabs
fi

# Set up the search paths:
PATH=$PATH:.

# Set up the shell environment:
set -u
trap "echo 'logout'" 0

# Set up the shell variables:
EDITOR=vi
export EDITOR

How about the nesting the test for the TERM variable within the test for interactive or batch mode of operation i.e.

if [ -t ]; then
if [ "$TERM" = ""]; then
eval ` tset -s -Q -m ':?hp' `
else
eval ` tset -s -Q `
fi
fi

Hi,

read Sandman's first line as
if [ -t 1 ]; then

Hi,

what about attaching your modified $HOME/.profile ?

Based on your .profile, you don't need it at all. Everything in it refers to an interactive session and does not setup anything for your database environment. And since your example is just running the script from your current login, running .profile in the script makes no sense. Are you testing this script for a cron job? If so, then the environment you need was setup in /etc/profile. I would not try to source /etc/profile but instead, just add the needed environment commands into your script.
