How to create file on Linux using environment variable in the dirpath
Hi all,

I am running a Java program on a Linux server in which I read in a base directory path from the *.properties file. During processing, I build a unique file name and create a file to save data, concatenating the directory path and the file name. Works fine, except that I now need to modify this code to accept an environment variable as part of the directory path (previously it was uniquely specified). I've experimented with various ways of quoting - no luck. I'm sure there's a simple syntax to permit this, but so far I've been unable to find it.

File creation statement looks like this:

File uploadFile = new File(baseDir + newFileName);

where baseDir has been read in from the properties file and is equal to

$MYFILEDIR/reports/

The file creation is failing.

Can anyone tell me what syntax can I use in the input that would allow me to create the file in the expected directory? Thanks so much.
