Re: [cli] absolute file path parsing

[Bernd Eckenfels]

If this is unix/Linux you cannot type \ on the command line without quoting, 
that's not related to Java. You can double the backslash or put it in "quotes". 
If you expect more characters which should not interpreted by the shell, use 
single quotes. CLI cannot work around this, it simply does not get the 
character passed. Since this affects all Linux commands you won't need to deal 
with this.

Subject: [cli] absolute file path parsing

I am using the apache.commons.cli CommandLineParser and am running into the 
following problem.

$ java -jar ./target/sorteria-0.0.1-SNAPSHOT-jar-with-dependencies.jar -f 
C:\shared\HCPAnywhere\AW001_3.0.0.20.iso -t ISO
test = C:sharedHCPAnywhereAW001_3.0.0.20.iso
File = C:sharedHCPAnywhereAW001_3.0.0.20.iso

When getting the -f option which is going to be an absolute file path the 
parser removes the \ character.  If I use \\ this works fine

$ java -jar ./target/sorteria-0.0.1-SNAPSHOT-jar-with-dependencies.jar -f 
C:\\shared\\HCPAnywhere\\AW001_3.0.0.20.iso -t ISO
test = C:\shared\HCPAnywhere\AW001_3.0.0.20.iso
File = C:\shared\HCPAnywhere\AW001_3.0.0.20.iso


I don't want the end user of this tool to have to know to do this though.  Is 
there a way for the parser to handle the \ character?  Maybe in the creation of 
the options?  What I have for creating this option is

Option file = new Option("f", "file", true, "Absolute File and Location");
file.setRequired(true);
options.addOption(file);
