RE: {.} {/} {/.} ...

[Cook, Malcolm]

Ole,

Such a feature would be useful whenever you wanted to place the output of 
processing a file in the same directory as the file.  For instance, untarring 
all the tar files found recursively in a directory tree.

Actually, having something like `find -execdir`, which runs the exec after 
cd-ing to the directory holding the found file, would serve the purpose as 
well, if not better.  Perhaps rather add a -cd option to `parallel` which would 
force cd prior to launching the process.  

All of these are perhaps only useful in multicore on single server, not 
distributed parallelism....????
