Im attempting to copy node_modules to a build directory for packaging into an electron application.

It appears that shx silently fails after 72 items.
I checked to make sure it wasn't hiccuping on the last directory it copied 'history', by deleting 'history'. The next alphabetical directory was then copied but no more. ie I think theres a limit on the number of items that can be copied.

shx mkdir ./build/node_modules && shx cp -r ./src/node_modules/* ./build/node_modules

works fine, but

shx cp -r ./src/node_modules ./build/node_modules

does not, while

cp -r ./src/node_modules ./build/node_modules

works as expected.

Ive tried verbose logging, but it just reprints the command. Could it have anything to do with the ulimit being reached on the device as I know I had issues with that and webpack. The solution was to make webpack only process so many files at a time, as the ulimit couldn't be increased.

Im on OSX.
