Linux more command

Linux Command大全

The Linux more command is similar to cat, but it displays content page by page, which is more convenient for users to read page by page. The most basic command is to press the space key (space) to display the next page, press the b key to display one page back, and it also has the function of searching for strings (similar to vi). For usage instructions, press h.
