Sebb commented on EXEC-83:
--------------------------
I don't think the bash script test shows the full details.
How many parameter values are detected?
And what are the individual values?
If an individual parameter contains a space, then it must be quoted, otherwise
the shell will treat it as multiple parameters.
That won't in general have the same result.
Try creating a simple Java app that prints out the arg count and lists each
parameter value; then call that from bash.
> Arguments with spaces lead to quotes in arguments in bash

> Key: EXEC-83
> URL: https://issues.apache.org/jira/browse/EXEC-83
> Project: Commons Exec
> Issue Type: Bug
> Affects Versions: 1.2
> Environment: Java 7 & OSX
> Reporter: Kevin Brown
> Priority: Minor
>
> If I run my script directly from a bash prompt I see a different behavior
> than if I launch with commons-exec. This may be the nature of the beast
> (java Runtime-exec interacting with bash), but leads me to have to rewrite
> scripts to remove extraneous quotes.
> Here is my script:
> $ cat ./foo.sh
> #!/bin/bash
> echo "$@"
> case I: commons-exec with no spaces ==> arguments do NOT have quotes when in
> bash script
> cmdLine=[/opt/bmam/bin/avidcommand/write_xmp_remote.sh, 70059021,
> RAW-one_two_three, http://foo.com]
> output (of $@):
> 70059021 RAW-one_two_three http://foo.com
> case II: commons-exec with spaces ==> arguments have quotes when in bash
> script
> cmdLine=[/opt/bin/foo.sh, 70058269, "AIR-one two three", http://foo.com]
> output (of $@):
> 70058269 "AIR-one two three" http://foo.com
> case III: execute directly from bash ==> arguments do NOT have quotes when in
> bash script
> $./foo.sh 70058891 "one two three" http://foo.com
> output (of $@):
> 70058891 one two three http://foo.com
