I'd like to install the image editing CLI program NConvert to WSL, but I'm not sure if this is possible, since NConvert isn't in any repository. There is a procedure I could implement to attempt an installation, but I'm cautious, as I don't want to break anything.
I was considering installing it with the following steps:
ubuntu@DESKTOP-NAC9118:~$ wget http://download.xnview.com/NConvert-linux64.tgz
ubuntu@DESKTOP-NAC9118:~$ tar xvzf NConvert-linux64.tgz
ubuntu@DESKTOP-NAC9118:~$ cd NConvert
ubuntu@DESKTOP-NAC9118:~/NConvert$
This last step has me confused, as I'm not sure if I should copy the NConvert executable to C:\Users\dmm\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\rootfs\usr\bin\ or someplace else. I would also need to open the bin folder in root and change the permissions of NConvert with chmod -R 755.
EDIT: I solved the problem. The mistake I was making was assuming there was no /usr/bin folder into which to copy nconvert, because when I ran ls at the Ubuntu prompt it didn't show me the FHS, but just some files. I needed to run ls / and then I was able to see the FHS. I copied nconvert into /usr/bin and did chmod and it works fine now. – user8547
I advise you NOT to copy the executable to that directory. You can use sudo to copy it to /usr/local/bin/. It would be better to add the directory of the executable to your PATH in ~/.bash_profile or ~/.profile.
