I'm trying to write a bash script to perform basic arithmetic operations but I want to run a comparison on the arguments first to check that they're a number greater than zero.
I want an error to pop up if the arguments args aren't >= 0 so I have:
But whenever I type in something like "blah + 9" it should tell me "bad number: blah", instead it treats "blah" as a zero and it gives the output as 9. If I use -gt 0 it eliminates the "blah" but also doesn't let me use zeros.
I need some help with a script which accepts multiple rows of input (analysis from a virtual robot's testrun) from the standard in, and compares it as a whole with another file featuring erroneous data from a virtual robot's test run. What I want it to be able to do is slice off all the erroneous... (2 Replies)

css::dom::rule
CSS::DOM::Rule(3pm) User Contributed Perl Documentation CSS::DOM::Rule(3pm)NAME
CSS::DOM::Rule - CSS rule class for CSS::DOM
VERSION
Version 0.14
SYNOPSIS
use CSS::DOM::Rule ':all'; # import constants
use CSS::DOM;
$sheet = new CSS::DOM;
$sheet->insertRule('bla blah blah {}');
$rule = $sheet->cssRules->[0];
$rule->type; # STYLE_RULE
$rule->cssText; # 'bla blah blah {}' or similar
$rule->cssText('p { margin: 0 }'); # replace it
$rule->parentStyleSheet; # $sheet
DESCRIPTION
This module provides the CSS rule class for CSS::DOM. It implements the CSSRule and CSSUnknownRule DOM interfaces.
METHODS
Constructor
Only call the constructor on this class to create an 'unknown' rule. You have to call the constructor on a particular subclass to get
another type. Normally you do not need to call this directly anyway. (See CSS::DOM's "parse" and "insertRule" methods.) But just in case
you do want to call it, here it is:
new CSS::DOM::Rule $parent; # unknown rule
require CSS::DOM::Rule::Style
new CSS::DOM::Rule::Style $parent;
# etc.
$parent is the parent rule, if the rule is nested, or the parent style sheet otherwise.
Object Methods
type
Returns one of the constants below indicating the type of rule.
cssText
Returns this rule's CSS code. If you pass an argument, it will be parsed as the new CSS code for this rule (replacing the existing
data), and the old value will be returned. This method will die if the replacement CSS code creates a different type of rule.
parentStyleSheet
This returns the style sheet to which the rule belongs.
parentRule
This returns the rule's parent rule, if there is one, or an empty list otherwise. There is only a parent rule if this one is nested,
e.g., inside a media rule.
EXPORTS
The following constants that indicate the type of rule will be exported on request (individually or with the ':all' tag):
UNKNOWN_RULE
STYLE_RULE
CHARSET_RULE
IMPORT_RULE
MEDIA_RULE
FONT_FACE_RULE
PAGE_RULE
