How to make bash wrapper for java/groovy program with variable length arguments lists?
The following bash script does not work because the java/groovy code always thinks there are four arguments even if there are only 1 or 2. As you can see from my hideous backslashes, I am using cygwin bash on windows.
How can I fix this problem with bash or some other shell?
I would like to know how to fix this problem with cmd.exe but I fear this is the wrong forum for that! (If anyone knows, please let me know!)
Thanks,
siegfried

Very, very new to unix scripting and have a unique situation. I have a file of records that contain 3 records types:

I have two very large datasets (>100MB) in a simple vertical list format. They are of different size and with different order and formatting (e.g. whitespace and some other minor cruft that would thwart easy regex).

The arguments are strings. In my code I need them to be a different type, I do the cast but it is not feasible ...
Have you any idea?

Dear Users,
I have installed a standalone program to do multiple sequence alignment which takes user parameters to run the program. I have multiple sequence files and want to automate this process through a bash script. I have tried to write a small bash code but its throwing errors.

I can't seem to get this right. I've tried it every way imaginable using every trick I see on stackexchange and such. No luck. So nothing major here, something like:

JAVA-WRAPPERS(7) Java wrappers JAVA-WRAPPERS(7)NAME
java-wrappers - capacities shared by java wrapper scripts
DESCRIPTION
Most Java programs are not run directly, but through small shell scripts that take care of various things, such as finding a suitable java
environment and looking for libraries.
To ease the task of the maintainers, they rely on a library providing runtime detection, library detection and other features. This manual
page describes the common features of all those scripts, and to which point you can configure them. This is mainly done via environment
variables.
ENVIRONMENT VARIABLES
java-wrappers understands some environment variables:
JAVA_CMD
The java command that will be run. If this variable is set, it disables all lookup for a java runtime.
JAVA_BINDIR
Specifies a directory that will be looked for a java or a jdb executable (depending on the setting of JAVA_DEBUGGER). It has prece-
dence over JAVA_HOME but not over JAVA_CMD.
JAVA_HOME
A path to a java runtime. If this variable is set, all lookup for a java runtime is disabled, except that if no java executable is
found in the path, the command java is used.
JAVA_FLAVOR
A probably more easy-to-use version of the JAVA_HOME variable: instead of specifying the full path of the java runtime, you name it.
List of available flavors can be found in the file /usr/lib/java-wrappers/jvm-list.sh. See examples below.
JAVA_DEBUGGER
If this is set, the wrapper will try to pick up a java debugger rather than a java interpreter. This will fail if the jbd of the
runtime found is a stub.
JAVA_CLASSPATH
Additional classpath, will have priority over the one found by the wrapper.
JAVA_ARGS
Additional arguments to the java command. They will come before all other arguments.
FORCE_CLASSPATH
If this variable is set, it will be the only classpath. You'd better know what you are doing.
DEBUG_WRAPPER
This is probably the most important variable; if it set, the wrapper will print out useful information as it goes by its business,
such as which runtime it did find, and which command is run eventually.
JAVA_JARPATH
The path where the wrappers will go looking for jar archives. If not set, the wrapper will look into the default directory,
/usr/share/java. Warning : the wrapper will not look anywhere else than in JAVA_JARPATH. Setting it incorrectly will most probably
result in early crashes.
EXAMPLES
The examples all rely on rasterizer(1), from the package libbatik-java, but they really apply to all scripts that use java-wrappers.
Print out debugging information:
DEBUG_WRAPPER=1 rasterizer
Limit rasterizer's memory to 80 MB:
JAVA_ARGS=-Xmx80m rasterizer
Force rasterizer to run with kaffe(1):
JAVA_HOME=/usr/lib/kaffe rasterizer
The same, but using JAVA_BINDIR:
JAVA_BINDIR=/usr/lib/kaffe/bin rasterizer
Force rasterizer to run with openjdk:
JAVA_FLAVOR=openjdk rasterizer
Debug rasterizer with Sun's debugger, while printing debugging information from the wrapper:
DEBUG_WRAPPER=1 JAVA_CMD=/usr/lib/jvm/java-6-sun/bin/jdb rasterizer
BUGS
Care has been taken to make the wrappers bug-free. If that was not the case, please file a bug report against the java-wrappers package.
If you wish to submit any problem with a java executable relying on java-wrappers, please also submit the output of the command run with
DEBUG_WRAPPER=1. It will save one mail exchange and therefore potentially reduce the time it takes to fix the bug.
DEVELOPERS
There is currently no documentation about writing a wrapper script save the comments in /usr/lib/java-wrappers/java-wrappers.sh. If you
have to write one, we suggest you base yourself upon, for instance, the rasterizer wrapper script, or any other one (just pick up any
direct reverse dependency of java-wrappers and look for scripts).
