I think most of the commands discussed are basic level and should be named as beginners rather than Admin only.

For the FTP command sample to get or to put *.txt files, show the command example once you log in to the remote site where the prompt would show 'ftp>' as opposed to your local root user prompt '#'.

Anyways, tecmint.com is a good reference place to both learn and refer to for all Unix users. I happened to search for a Wi-Fi setup issue on a desktop/CentOS. I am a Unix fan, though I have not used it much in the last 20 years.

I am Raj, just a blog reader. While I was reading through this content (https://www.tecmint.com/useful-linux-commands-for-system-administrators/) I noticed that the CAT command is not defined correctly since cat (short for concatenate) command are used to create single or multiple files, view content of a file, concatenate files and redirect output in terminal or files. The pipe symbol ( | ) allows us to add multiple commands in a single command.

Hope to see you correct the blog post.

Thank you,
Your’s Sincerely,
Raj

# ftp > mput *.txt
# ftp > mget *.txt

Should it be:

# ftp < mput *.txt
# ftp < mget *.txt
