Conventional Search Tools and Their Corresponding "Modern" Alternatives

Tools like find, du, grep, and ls etc. and their combination (via pipe) are used in my daily life. For example, to list the files or directories with size larger than 1 gigabyte:

du -h -t 1G

I don't use more "modern" or "fancier" tools because I am not familiar with them. The conventional approach fits my daily life very well. However, I am thinking if I can keep improving my efficiency and productivity by using some alternatives when necessary. Here are some of them.

mc

• mc a.k.a. GNU Midnight Commander, which is a visual shell for Unix-like systems.
• Press F10 to quit the dashboard.

fzf

• fzf a.k.a. fuzzy finder.
• Input nothing and press enther to quit the search.
• Key-in any characters to perform fuzzy search.

ncdu

• ncdu a.k.a. ncursers disk usage.
• Press q to quit the application.
