Looks like a bug. I can repro on my Linux system as well. Let me know if you're interested in sending a fix. |

Looks like a bad interaction with passing directories as arguments. shx cp -RLu srcDir/baz.txt targDir/srcDir/baz.txt # No bug
shx cp -RLu srcDir targDir # This has the bugThis was probably a case I overlooked in the original implementation of the feature. |

A fix would be great if you have one. I haven't actually looked at the code
behind shelljs...

Does shelljs support the -p option to preserve timestamp information? |
|
shelljs cp command ought to support a -p (preserve) option to preserve timestamps. Something along the lines of: copyFileSync in cp.js should check for the preserve option and copy the timestamps. |
I'm using NodeJS v10.13.0, with shelljs 0.8.3, under Mac OSX 10.13.6, and am performing a copy command, such as:
My understanding is that -u should copy only newer files. But, after a copy, I am seeing the timestamp on the existing files in the target directory are changed to the current time, thus defeating the point of the copy operation to leave existing files unchanged.
