NikosAlexandris wroteDears, before creating the HPC related Wiki, I would like to ask for your advise on hard-linking raster maps files. Soeren suggested this as a tip, I understand to save time and space. Hard-linking was also mentioned inside the JEODPP (JRC) team at some point. I have implemented hard-linking raster maps in https://gitlab.com/NikosAlexandris/r.internal.sh. It's a shell script, does not compile. Will convert in Python, if useful. If you hard-link files, how do you perform it? If of your interest, what do you think about it? What would be important considerations to pay attention to? Would you name such a module differently? Would you consider soft-linking in addition or instead of? Would you add a "dry-run" option (as in "don't do anything, just show what you want to do")? Thank you, Nikos _______________________________________________ grass-dev mailing list[email protected]https://lists.osgeo.org/mailman/listinfo/grass-dev signature.asc (235 bytes) <http://osgeo-org.1560.x6.nabble.com/attachment/5365206/0/signature.asc>Would this be portable to other operating systems than linux Like e.g. windows?
I wouldn't know, it depends (also) on the underlying file system. While it works for my purpose, I would like to avoid common wrong-doings. Reading about it (Wikipedia and else), I understand that it is doable. The Python 2 function `os.link()` [0] is marked with "Availability: Unix.". I don't know how easy it is to implement it. Support for Windows was added after 3.2 [1]. I guess it concerns NTFS. [0] https://docs.python.org/2.7/library/os.html?highlight=os%20link#os.link [1] https://docs.python.org/3.5/library/os.html?highlight=os.link#os.link I regret for not writing in Python. It seems to me harder to implement and maintain such a in Bash. Will convert for sure as soon as I find the time. Cheers, Nikos
