My script does not work - could you pls help?
Hi all,
I put together a script that seems not working as I would like to and after spending hours to find the problem I decided to ask your help.
The thing I am trying to do is call AWK command on the TRUE branch of if statement. Else branch should only print out a message to screen.
This is the code I am using:
...
for printer in "$@" ; do
lpstat $printer|grep $printer |grep '-' >$TEMP_FILENAME
grep '-' $TEMP_FILENAME
status=$?
if [[$status -eq 0]] ; then
awk '
{
here I do some stuff...
}
' $TEMP_FILENAME
else
echo "No jobs in the printer queue $printer ..."
fi
done
The result I got is not what I expect:
printerjob1 user priority 0 Jun 27 08:26
printerjob2 user priority 0 Jun 28 13:38
./prg.sh[103]: [[0: not found
No jobs in the printer queue printername ...
So for me it seems program executes somehow both branches of the IF statement.
The line 103 where the problem is indicated is:
if [[$status -eq 0]] ; then
I could not solve it , so please recommend me what the problem might be...
Thank you!

service(8) System Manager's Manual service(8)
NAME
service - run a System V init script
SYNOPSIS
service SCRIPT COMMAND [OPTIONS]
service --status-all
service --help | -h | --version
DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
directory set to /.
The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the
invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and
stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start
command.
service --status-all runs all init scripts, in alphabetical order, with the status command.
EXIT CODES
service calls the init script and returns the status returned by it.
FILES
/etc/init.d
The directory containing System V init scripts.
ENVIRONMENT
LANG, TERM
The only environment variables passed to the init scripts.
SEE ALSO
/etc/init.d/skeleton,
update-rc.d(8),
init(8),
invoke-rc.d(8).
