Which command is used to organize a text file alphabetically?

The command used to organize a text file alphabetically is the sort command. This command reads the input text, sorts the lines in a specified order (default is ascending alphabetically), and then outputs the sorted text. It is highly versatile and can sort based on different criteria, such as numerical values, or specified fields within complex data formats, often used in conjunction with output redirection to save the sorted data to a new file or to display it in the terminal.

In contrast, the other commands serve different purposes. The cat command is primarily utilized for displaying the contents of a file, combining multiple files, and creating new files, but it does not alter or organize the data. The find command is used for searching files and directories based on specific criteria, such as name or modification time, rather than organizing text. The echo command is employed for printing strings or variables to the terminal, not for organizing file contents. Thus, sort is the appropriate choice for alphabetically arranging the lines in a text file.
