Help plz
Does any one have any idea how to compare interval ranges of 2 files.
finding 1-4 (1,2,3,4) of input2 in input1 of same key "a" values (5-10, 30-40, 45-60, 80-90, 100-120 ). Obviously 1-4 is not one of the range with in input1 a. so it should give out of range.
finding 30-33(31,32,33)... (1 Reply)
Hi,
I need a script/command to list out all the files in current path and also the files in folder and subfolders.
Ex: My files are like below
$ ls -lrt
total 8
-rw-r--r-- 1 abc users 419 May 25 10:27 abcd.xml
drwxr-xr-x 3 abc users 4096 May 25 10:28 TEST

Under TEST, there are... (2 Replies)
Hi,
My requirement is,there is a directory location like:
:camp/current/
In this location there can be different flat files that are generated in a single day with same header and the data will be different, differentiated by timestamp, so i need to verify how many files are generated... (10 Replies)
Hi frnds,
My requirement is I have a zip file with name say eg: test_ABC_UH_ccde2a_awdeaea_20150422.zip
within that there are subdirectories on each directory we again have .zip files and in that we have files like mama20150422.gz and so on.
Iam in need of a bash script so that it unzips... (0 Replies)
Hi,
I developed a script which finally originates a similar output:
net0:up,Tx=475198bps,Rx=31009bps net1:up,Tx=39596bps,Rx=35678bps
Of course the figures change and also the amount of interfaces (ex: could be more then net0 and net1). This is done automatically.
The next step i'm... (4 Replies)

Data::Compare::Plugins(3) User Contributed Perl Documentation Data::Compare::Plugins(3)NAME
Data::Compare::Plugins - how to extend Data::Compare
DESCRIPTION
Data::Compare natively handles several built-in data types - scalars, references to scalars, references to arrays, references to hashes,
references to subroutines, compiled regular expressions, and globs. For objects, it tries to Do The Right Thing and compares the
underlying data type. However, this is not always what you want. This is especially true if you have complex objects which overload
stringification and/or numification.
Hence we allow for plugins.
FINDING PLUGINS
Data::Compare will try to load any module installed on your system under the various @INC/Data/Compare/Plugins/ directories. If there is a
problem loading any of them, an appropriate warning will be issued.
Because of how we find plugins, no plugins are available when running in "taint" mode.
WRITING PLUGINS
Internally, plugins are "require"d into Data::Compare. This means that they need to evaluate to true. We make use of that true value.
Where normally you just put:
1;
at the end of an included file, you should instead ensure that you return a reference to an array. This is treated as being true so
satisfies perl, and is a damned sight more useful.
Inside that array should be either a description of what this plugin is to do, or references to several arrays containing such
descriptions. A description consists of two or three items. First a string telling us what the first data-type handled by your plugin is.
Second, (and optional, defaulting to the same as the first) the second data-type to compare. To handle comparisons to ordinary scalars,
give the empty string for the data-type, ie:
['MyType', '', sub { ...}]
Third and last, we need a reference to the subroutine which does the comparison. That subroutine should expect to take two parameters,
which will be of the specified type. It should return 1 if they compare the same, or 0 if they compare different.
Be aware that while you might give a description like:
['Type1', 'Type2', sub { ... }]
this will handle both comparing Type1 to Type2, and comparing Type2 to Type1. ie, comparison is commutative.
If you want to use Data::Compare's own comparison function from within your handler (to, for example, compare a data structure that you
have stored somewhere in your object) then you will need to call it as Data::Compare::Compare. However, you must be careful to avoid
infinite recursion by calling D::C::Compare which in turn calls back to your handler.
The name of your plugins does not matter, only that it lives in one of those directories. Of course, giving it a sensible name means that
the usual installation mechanisms will put it in the right place, and meaningful names will make it easier to debug your code.
For an example, look at the plugin that handles Scalar::Properties objects, which is distributed with Data::Compare.
DISTRIBUTION
Provided that the above rules are followed I see no reason for you to not upload your plugin to the CPAN yourself. You will need to make
Data::Compare a pre-requisite, so that the CPAN.pm installer does the right thing.
Alternatively, if you would prefer me to roll your plugin in with the Data::Compare distribution, I'd be happy to do so provided that the
code is clear and well-commented, and that you include tests and documentation.
