cat – Concatenate and Display File Content

The cat command is used to display the content of a file on the terminal. It is also used for file concatenation.

Examples:

• To display the content of a single file:

cat filename

• To display the content of multiple files together:

cat file1 file2

• To concatenate the content of multiple files and save it to a new file:

cat file1 file2 > newfile

• Important Points:
  • While cat is useful for small files, it may not be the best choice for large files, as it displays everything at once.
  • For larger files, consider using less or more to view the content page by page.
