If the port installs a shell script whose purpose is to launch another program,
and if launching that program is the last action performed by the script, make sure
to launch the program using the
exec statement, for
#!/bin/sh exec %%LOCALBASE%%/bin/java -jar %%DATADIR%%/foo.jar "$@"
exec statement replaces the shell process with
the specified program. If
exec is omitted, the shell
process remains in memory while the program is executing, and needlessly
consumes system resources.
