komentorivivalinnat

Komentorivivalinnat, often referred to as command-line arguments or flags, are a way to pass information to a program when it is executed from the command line. These choices modify the program's behavior or specify the data it should operate on. Typically, they precede the program's name or follow it, and are often distinguished by a hyphen (-) or a double hyphen (--) followed by a short keyword or an abbreviation.

For example, a command like `ls -l` uses the `-l` flag to instruct the `ls` command (list directory contents) to display output in a long format, providing more details about each file. Similarly, a command like `grep --ignore-case pattern file.txt` uses the `--ignore-case` option to make the `grep` command search for the specified pattern without regard to letter case.

The specific set of available komentorivivalinnat is entirely dependent on the program itself. Each application defines its own unique options, which are usually documented in the program's manual pages or help files. Understanding these options is crucial for effectively utilizing many command-line tools, allowing users to customize their execution and achieve specific outcomes. They provide a powerful and flexible way to interact with software without needing a graphical user interface.
