To reuse a command, use Ctrl + R and type a few matching keywords to see the recently used cmds being shown up. The search is based on the command history.
If you want to run multiple commands at once, you can chain then together with 3 options: ; - Run commands sequentially, && - If one cmd fails then the next won't run, || - Command runs only if the previous cmd fails.
Viewing a file with large data using 'cat' spams the whole window, using 'less' shows a chunk of content and then you can scroll up or down. Features: Search for specific terms, navigation shortcuts like G and 1G, options like -N (display line numbers) and -i (ignore case).
Using the 'column' command, view text files or command outputs in a more readable tabular format. Utilize -t for tabular view and -s to specify the delimiter. Example: 'column -s ',' -t data.csv'
