Dear all.

I'm moving from Redhat to slackware.
I have several scripts that were working on Redhat but are not working on Slackware.

Please help.

1. /etc/profile.d/setjava.sh
----------------------------
# This script call Java initialisation script
# if the user is member of java group
#--------------------------------------------

### THIS if LINE IS NOT WORKING ON SLACK
### Telling something about unary operator expected
if [ `id -n -G | grep java` ]; then
source /java/bin/setjava.sh
echo "Java is ready at $JAVA_HOME"
fi

2. /etc/rc.d/init.d/jetty.sh
-----------------------
#!/bin/sh
#
# chkconfig: 345 80 20
# description: jetty
# processname: jetty
#
# This script is installed at /etc/rc.d/init.d/
# Part of sysvinit on redhat.
# Called directly from /etc/rc.d/rc.local on slackware
# source /etc/rc.d/init.d/jetty.sh start
# -----------------------------------------------------

CONFIGS="jetty4.xml"
USER="java"

# Setting Jetty
# Lihat $JETTY_HOME/bin/jetty.sh
JETTY_HOME="/java/server/jetty"
JETTY_RUN="/var/jetty"
JETTY_CONSOLE="$JETTY_RUN/console.txt"
JETTY_PID="$JETTY_RUN/jetty.pid"
JETTY_LOG="$JETTY_RUN/"

# Setting Java
JAVA_HOME=/usr/java/j2sdk
JAVA="$JAVA_HOME/bin/java -server"
JAVA_OPTS=""

export JAVA_HOME JAVA JAVA_OPTS
export JETTY_HOME JETTY_CONSOLE JETTY_RUN JETTY_PID

# Hapus $JETTY_PID jika tidak sah
if [ -f $JETTY_PID ]; then
PID=`cat $JETTY_PID`
RUNNING=`ps -p $PID | grep $PID`
if ! [ "$RUNNING" ]; then
rm $JETTY_PID
fi
fi

cd $JETTY_HOME

### IT IS NOT WORKING HERE.
### The initialisation stop into a shell.
### I had to type exit or press Ctlr-C to continue the boot process
su -m -s "/bin/sh" -c "$JETTY_HOME/bin/jetty.sh $1 $CONFIGS" $USER


3. jetty.sh
--------------------------
This is the original jetty.sh from jetty distribution.
I called it directly, and it said: "unary operator expected at line 429".
Here is the line

JAVA_VERSION=`expr "$($JAVA -version 2>&1 | head -1)" : '.*1\.\([0-9]\)'`

#####################################################
# Build the classpath with Jetty's bundled libraries.
#####################################################
### LINE 429
if [ $JAVA_VERSION -lt 4 ]
then
CP=$(ls $JETTY_HOME/ext/*.jar $JETTY_HOME/lib/*.jar | \
egrep -v org.mortbay.jetty.jar | \
paste -s -d"$PATH_SEPARATOR" - )
else
CP=$(ls $JETTY_HOME/ext/*.jar $JETTY_HOME/lib/*.jar | \
egrep -v org.mortbay.jetty-jdk1.2.jar\|crimson.jar\|javax.xml.jaxp.jar | \
paste -s -d"$PATH_SEPARATOR" - )
fi

Well, you want to make sure all the path's are correct in your script, as they may differ from Redhat and Slackware most likely.

One I can see clearly is:

2. /etc/rc.d/init.d/jetty.sh

Slackware doesn't have a /etc/rc.d/init.d directory but is totally different with just a /etc/rc.d directory.. and so on..

You'll most likely need to customize the script for Slack to work.

Nothing wrong with the path. I have properly customized it.
But the problem is with the command. See again
1.-------------------
if [ `id -n -G | grep java` ]; then ## PROBLEM HERE
source /java/bin/setjava.sh
echo "Java is ready at $JAVA_HOME"
fi

If I run this command with a certain user (with 3 groups)
$ id -n -G | grep java
users java share

See that it prints 3 groups.
But inside the script, it raises the error.
All I wanna do is to check if the string is empty,
then the user is not a member of java group.

2.----------------
su -m -s "/bin/sh" -c "$JETTY_HOME/bin/jetty.sh $1 $CONFIGS" $USER

I want to run jetty as user $USER, not as root.
This command should:
* change user to $USER
* launch a shell (bin/sh)
* execute the script (jetty.sh)

But it does not. It only launches the shell then stops there waiting.

3. -------
if [ $JAVA_VERSION -lt 4 ]
....
fi
This should be simple.
if JAVA_VERSION less than 4 then do something.
What is the comparison operator on slackware ?

I wonder what is the difference between /bin/sh on slackware and /bin/sh on redhat ?

Dear all.

I found the problem.

1.-------------------
Corrected to:
GROUP=`id -n -G | grep java`
if [ "$GROUP" ]; then ## NO PROBLEM ANYMORE
source /java/bin/setjava.sh
echo "Java is ready at $JAVA_HOME"
fi

2&3
-----
The culprit is the Java. In Redhat I was using Sun JDK, but IBM JDK in Slack.
To call the java, I have setup environment variable:
JAVA="/opt/java/java -server"

It works for Sun but not for the IBM, so the script does not work.


Sorry for the trouble.

Cheers.
