pages in core, a file size, and a file name. If an error

The default output is subject to change. So whenever possible, you should
|
|
|
|
|
avoid using default outputs in your scripts. Always explicitly define expected
|
|
|
|
|
columns by using
|
|
|
|
|
.B \-\-output
|
|
|
|
|
.I columns-list
|
|
|
|
|
in environments where a stable output is required.
