Options<br />

As a special notation, most <strong>MKS</strong> <strong>Toolkit</strong> <strong>com</strong>mands let you specify --<br />

to separate <strong>the</strong> options from <strong>the</strong> non-option arguments; -- says,<br />

`There are no more options'. Therefore, if you really do have a<br />

directory named -d and want to list its contents, you could say<br />

lc -- -d<br />

With <strong>the</strong> <strong>MKS</strong> <strong>Toolkit</strong>, you can specify more than one simple option<br />

to a <strong>com</strong>mand. For example, -c and -n are both simple options that<br />

can be specified with <strong>the</strong> pg <strong>com</strong>mand. You could say<br />

pg -c -n file<br />

or you could <strong>com</strong>bine <strong>the</strong> two options into<br />

pg -cn file<br />

The order <strong>of</strong> <strong>com</strong>bined options is not important;<br />

pg -nc file<br />

is equivalent to <strong>the</strong> previous version <strong>of</strong> <strong>the</strong> <strong>com</strong>mand.<br />

In addition to simple options, some <strong>com</strong>mands accept options that<br />

have ac<strong>com</strong>panying values. Such options look like simple options<br />

followed by additional information. This information may be a<br />

number, a string, <strong>the</strong> name <strong>of</strong> a file, or something else.<br />

If you read <strong>the</strong> pg reference page in <strong>the</strong> online <strong>MKS</strong> <strong>Toolkit</strong> Utilities<br />

Reference, you can see that pg accepts an option <strong>of</strong> <strong>the</strong> form<br />

-p prompt<br />

When <strong>the</strong> reference pages show part <strong>of</strong> a <strong>com</strong>mand line in italics, <strong>the</strong><br />

italicized material is just a placeholder; when you actually use <strong>the</strong><br />

<strong>com</strong>mand, you should fill in something else in its place. In this case,<br />

<strong>the</strong> prompt should be a string <strong>of</strong> characters, enclosed in single quotes.<br />

For example, in <strong>the</strong> <strong>com</strong>mand<br />

pg -p 'More?' file<br />

<strong>the</strong> prompt string is More? If you execute <strong>the</strong> above <strong>com</strong>mand, you can<br />

see that pg prints out<br />

More?<br />

when it pauses at <strong>the</strong> end <strong>of</strong> a screen, instead <strong>of</strong> <strong>the</strong> usual :. In o<strong>the</strong>r<br />

words, <strong>the</strong> -p prompt option lets you set pg's prompt.<br />

The help <strong>com</strong>mand lists information about <strong>MKS</strong> <strong>Toolkit</strong> <strong>com</strong>mands.<br />

Specify <strong>the</strong> name <strong>of</strong> <strong>the</strong> <strong>com</strong>mand to help as:<br />

help <strong>com</strong>mand<br />
