# Formatting a Command

You can use any one of the following formats to include commands on the command line:

- Command Options Format
- Single String Arguments Format
- Command File Format

All formats are used to accomplish the same tasks. Use the format that you prefer or that is easier to use. See Index of Available Commands for a complete listing of available commands.

## Command Options Format

In the command options format, commands are preceded by a dash (-), act as options, and do not use command terminators. Enclose complex command arguments in quotes. Use this format when long lists of commands are included in a command line.

Example:

> jtharness `-open` default`.jti -runtests`

## Single String Arguments Format

If you are setting several command options, you might want to use the single string arguments format. In the single string arguments format, one or more commands and their arguments can be enclosed in quotes as a single string argument. Multiple commands and arguments in the string are separated by semicolons.

Example:

> jtharness `"open` default`.jti; runtests"`

## Command File Format

If you are setting a series of commands and options, you can use the command file format. Using a command file enables you to easily reuse the same configuration.

In the command file format, a file containing a series of commands and their arguments is included in the command line by preceding the file name with the at symbol (@).

Example:

> jtharness `@`mycmd`.jtb -runtests`

Refer to Using Command Files for detailed information about using and creating command files.
