The explanation wise it was good, but more repetitive commands make us to confuse, rest other things are fine
bad job explaining what options and commands stand for
More command focused than analysis focused. Course was repetitive in both content and delivery, and ultimately felt a bit rushed. Would recommend that the author spend more time reviewing their lectures before uploading them.
Also gave some potentially misleading or outright incorrect information, such as the commentary around the inability to have multiple foreground tasks at once. That is not accurate unless you clarify that you mean for a given terminal. There were other errors as well but I don't recall the details.
And lastly some of the lecture headers don't match their content, such as #61, which suggests that it covers finding files and directories based on date, time and size but covers perm-based find commands and the -exec argument.
The sound cuts out sometimes. It seems to be inside the material itself as it can be reproduced when playing again in those spots.
