Subject [jira] [Commented] (EXEC-83) Arguments with spaces lead to quotes in arguments in bash
Date Thu, 20 Feb 2014 20:42:27 GMT

    [ https://issues.apache.org/jira/browse/EXEC-83?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13907470#comment-13907470
] 

Kevin Brown commented on EXEC-83:
---------------------------------

So it looks like quote handling is messing me up.  And I might have quotes in arg2.  Turning
off quote handling gives me what I expect in the log:

The number of arguments is: 3
The length of argument '100' is: 3
The length of argument 'kevin was here' is: 14
The length of argument 'three' is: 5

<sigh>

{code}
@Test
    public void testExecutor() throws IOException {

        String script="/Users/kevin/foo.sh";
        String arg1="100";
        String arg2="kevin was here";
        String arg3="three";

        CommandLine commandLine = new CommandLine(script);
        commandLine.addArgument(arg1, false);
        commandLine.addArgument(arg2, false);
        commandLine.addArgument(arg3, false);

        DefaultExecutor executor = new DefaultExecutor();
        executor.setExitValues(null); //check for exit values ourselves

        System.out.println("cmdLine="+ commandLine.toString());
        int exitValue = executor.execute(commandLine);
        System.out.println("exitValue="+ exitValue);
    }
{code}

>                 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
