# Creating a Command File

Use the single string arguments format style to write commands in a text file. See Formatting a Command for detailed information.

Command files can contain blank lines and comments as well as lines with commands and their arguments. The following table describes the contents of a command file.

File Contents | Description
--- | ---
Comments | Comments can begin anywhere on a line, are started by the pound symbol ( #), and stop at the end of the line. Example: `#File contains commands`
Commands | Commands are executed in the sequence that they appear in the file (for example, setup commands must precede task commands). Commands used in the file must be separated by a semicolon (;) or a new line symbol (#). The # symbol acts as a new line character and can terminate a command. Examples: `open` default`.jti; #opens file` `-set host` mymachine
Command Arguments | Arguments that contain white space must be placed inside quotes. Use a backslash (\) to escape special characters such as quotes (" ") and backslashes (\).

After writing the commands, use a descriptive name and the extension `.jtb` to save the text file. Choose a file name that helps you identify the function of each command file.
