I need urgent help with a small program that is run via shell script. Unfortunately I only understand the bare basics of shell scripting and can't figure out how to do this.
We have a program that tests the connection between 3 servers. I have a script that lets the program run on one specific server.
We have nearly the same directory structure on all servers and I need the script to be able to run this program from all servers without using individual scripts for each one.
That is we deploy the program and then simply copy the script from one server to the other 2.
Here is the script so far.
Code:
#!/bin/ssh
# resolve links - $0 may be a softlink
PRG="$0"
while [ -h "$PRG" ]; do
ls=`ls -ld "$PRG"`
link=`expr "$ls" : '.*-> \(.*\)$'`
if expr "$link" : '/.*' > /dev/null; then
PRG="$link"
else
PRG=`dirname "$PRG"`/"$link"
fi
echo "PRG = $PRG"
done
# Get standard environment variables
PRGDIR=`dirname "$PRG"`
# Only set $CT_HOME if not already set
# [ -z "CT_HOME" ] && CT_HOME=`cd "$PRGDIR/.." ; pwd`
CT_HOME=`cd "$PRGDIR/.." ; pwd`
# Make sure prerequisite environment variables are set
if [ -z "$JAVA_HOME" ]; then
# For our servers we assume our standard jdk location
if [ -d "/spd/iu/system/java/jdk1.6.0_65" }; then
JAVA_HOME="/spd/iu/system/java/jdk1.6.0_65"
echo "Seetting JAVA_HOME to $JAVA_HOME"
else
echo "Please set JAVA_HOME variable to a JDK >= 1.6.x"
exit 1
fi
fi
_RUNJAVA="$JAVA_HOME"/bin/java
# Set classpath
CLASSPATH="$CT_HOME"
CT_LIBDIR="$CT_HOME/lib"
if [ -d "${CT_LIBDIR}" ]; then
for i in "${CT_LIBDIR}"/*.jar; do
CLASSPATH="$CLASSPATH":"$i"
done
else
echo "Does not exist: ${CT_LIBDIR}"
fi
echo "CLASSPATH = ${CLASSPAT}"

Now I only get a fraction of what it does and the comments don't help me that much either.
Can anyone point me in the right direction?
Help would be much appreciated!

So far the only things referring to something unique on that server I found are:
In the last line:
Quote:
/spd/iu/web/kon/lib/
These directories have different names on each server.
And the arcjob-3-4-1.jar doesn't exist on all servers (I'll have to find an equivalent expression for each server).
But I still don't understand how this script is limited to only that one server, as I understand so little of what it does.
I understand that it checks for a symbolic link in the beginning, but everything else in the first while is lost on me.
The first thing I understand after that is when it sets the Java homedir.
Everything after that is lost on me again.

I found an older version of the script, not yet fitted to that server:
Code:
#!/bin/sh
# resolve links - $0 may be a softlink
PRG="$0"
while [ -h "$PRG" ]; do
ls=`ls -ld "$PRG"`
link=`expr "$ls" : '.*-> \(.*\)$'`
if expr "$link" : '/.*' > /dev/null; then
PRG="$link"
else
PRG=`dirname "$PRG"`/"$link"
fi
echo "PRG = $PRG"
done
# Get standard environment variables
PRGDIR=`dirname "$PRG"`
# Only set $CT_HOME if not already set
# [ -z "CT_HOME" ] && CT_HOME=`cd "$PRGDIR/.." ; pwd`
CT_HOME=`cd "$PRGDIR/.." ; pwd`
# Make sure prerequisite environment variables are set
if [ -z "$JAVA_HOME" ]; then
# For our servers we assume our standard jdk location
if [ -d "/spd/iu/system/java/jdk1.6.0_65" ]; then
JAVA_HOME="/spd/iu/system/java/jdk1.6.0_65"
echo "Setting JAVA_HOME to $JAVA_HOME"
else
echo "Please set JAVA_HOME variable to a JDK >= 1.6.x"
exit 1
fi
fi
_RUNJAVA="$JAVA_HOME"/bin/java
# Set classpath
CLASSPATH="$CT_HOME"
CT_LIBDIR="$CT_HOME/lib"
if [ -d "${CT_LIBDIR}" ]; then
for i in "${CT_LIBDIR}"/*.jar; do
CLASSPATH="$CLASSPATH":"$i"
done
else
echo "Does not exist: ${CT_LIBDIR}"
fi
echo "CLASSPATH = ${CLASSPATH}"
$_RUNJAVA -cp ${CLASSPATH} com.luz.telco.sandbox.tecon.ConnectionTest $@
Now the script works perfectly fine on that one machine, but it was designed to do so.
I need it to work on the other two, so that when tecon is deployed it can be run via the script. Creating a script for every server would work, but is not desired, we want one script that works on every server.
/spd/iu/web/kon/lib/ is /spd/iu/web/ent/lib on one and */prod/lib on the other.
If that's the only thing "personalized" about this script I just need a way for it to look for either of these.

Ok, I solved one of my problems.
Now:
Code:
# Set classpath
CLASSPATH="$CT_HOME"
CT_LIBDIR="$CT_HOME/lib"
if [ -d "${CT_LIBDIR}" ]; then
for i in "${CT_LIBDIR}"/*.jar; do
CLASSPATH="$CLASSPATH":"$i"
done
else
echo "Does not exist: ${CT_LIBDIR}"
fi
echo "CLASSPATH = ${CLASSPAT}"

The last two paragraphs should be in a environment variable. I was told, that I could somehow use the CLASSPATH bit to do this, but I don't know how.
