Fish (suggested by the article as well) is amazing. Also:

• bat (better cat),
• btm (better top),
• httpie (better curl),
• ripgrep (better grep),
• zoxide (cd with fuzzy search)
• jq (for manipulating JSON)

But honestly, lots of classics are still great: git, htop, rsync, vim, nano, …

I’m usually a bit scornful of “bling” commands, but bat seems genuinely useful.

Be careful not to replace bash with fish as some systems fail to work with new shell. I usually init fish/nu shells with other instruments, like alacritty and/or zellij
