Integer check (again)...
I have search the forum for an easier way to write this code. I have two separate 'if' to do this and it works but am wondering if someone knows a quick way to combine them. I want anything between 1 and 100 but not '01' or '005', '0010', etc.

Code:
     

if [[ $myvar != +([0-9]) ]] ||
   [[ $myvar -le 0 || $myvar -gt 100 ]]; then
   echo "Try again"
fi

After that check, I do another check with a grep to make sure it doesn't start with a zero (so this is the 'else' block of the above code):

Code:
if echo $myvar | grep '^[1-9][0-9]*'; then 
   echo "Cool"
fi

Any thoughts?

template::plugin::dumper

Template::Plugin::Dumper(3pm)				User Contributed Perl Documentation			     Template::Plugin::Dumper(3pm)

NAME

       Template::Plugin::Dumper - Plugin interface to Data::Dumper

SYNOPSIS

	   [% USE Dumper %]

	   [% Dumper.dump(variable) %]
	   [% Dumper.dump_html(variable) %]

DESCRIPTION

       This is a very simple Template Toolkit Plugin Interface to the Data::Dumper module.  A "Dumper" object will be instantiated via the
       following directive:

	   [% USE Dumper %]

       As a standard plugin, you can also specify its name in lower case:

	   [% USE dumper %]

       The "Data::Dumper" "Pad", "Indent" and "Varname" options are supported as constructor arguments to affect the output generated.	See
       Data::Dumper for further details.

	   [% USE dumper(Indent=0, Pad="<br>") %]

       These options can also be specified in lower case.

	   [% USE dumper(indent=0, pad="<br>") %]

METHODS

       There are two methods supported by the "Dumper" object.	Each will output into the template the contents of the variables passed to the
       object method.

   dump()
       Generates a raw text dump of the data structure(s) passed

	   [% USE Dumper %]
	   [% Dumper.dump(myvar) %]
	   [% Dumper.dump(myvar, yourvar) %]

   dump_html()
       Generates a dump of the data structures, as per dump(), but with the characters <, > and & converted to their equivalent HTML entities and
       newlines converted to <br>.

	   [% USE Dumper %]
	   [% Dumper.dump_html(myvar) %]
