If they can have a location fixed relative to the script, the Perl core module
FindBin and pragmatic module lib can help here:
Or if using bash or similar you take do something like this,
which is a simplified version of the Kawa start-up script:
#!/bin/bash
thisfile=`command -v $0`
case "$thisfile" in
"") echo "installation error - can't find path to $0"; exit -1 ;;
/*) ;;
*) thisfile="$PWD/$thisfile" ;;
esac
while test -L "$thisfile"; do thisfile=$(readlink -f "$thisfile"); done
kawadir=`dirname "$thisfile" | sed -e 's|/bin\(/\.\)*$||'`
CLASSPATH="$kawadir/lib/kawa.jar:${CLASSPATH}"
export CLASSPATH
exec ${JAVA-java} -Dkawa.home="${kawadir}" kawa.repl "$@"
The idea is you can have:
ANYDIR/bin/kawa
ANYDIR/lib/kawa.jar
ANYDIR/share/kawa/...
Then if you execute ANYDIR/bin/kawa directly, or via a symlink,
or if ANYDIR/bin (or a symlink) is on your PATH the script will set
$kawadir to ANYDIR. Given that it can find ANYDIR/lib/kawa.jar,
ANYDIR/share/kawa or other needed files.
