A more complex but more commonly used program is rsync
rsync -rav /home/user/Documents /mnt/usbdrive is treated differently than rsync -rav /home/user/Documents//mnt/usbdrive which is different than rsync -rav /home/user/Documents /mnt/usbdrive/ which is different than rsync -rav /home/user/Documents//mnt/usbdrive/
It’s a great tool for making copies onto drives, even servers. But man you have to double check how each folder path is laid out, otherwise it’ll write the files of one folder to the main drive, unorganized.
Tbh the frequent pain from needing to read it again often happens because it was so hard to write correctly that it misbehaves on some data and you need to adjust it.
The biggest pain in the ass I’ve dealt with was using a directshow lib to implement flash on a new camera we were supporting for a desktop application. Working with a device graph and pins is beyond frustrating. We’re porting functionality to the Web and my dev working on the camera just needed to call capture image to trigger the flash.
ffmpeg command lines are straight up black magic.
Anyone who understands them is not to be trusted.
It’s even worse than tar.
GNU tar is easy and straight-forward.
It’s also completely incompatible with any other Unix, but then, what difference does it make is nobody can use them?

I recommend
--dry-runand reading the stdout with human readable output-h. And dont use the--deleteflag if you dont know what will happen 😓If they know Regex, assume you are in Sarumans tower and held captive until a hawk comes in.
Writing regex is easy.
Reading it again after a couple of weeks…

It’s a write only language

ffmpeg commands are one of the best use cases for ChatGPT
