Grouping hostnames for pdsh

Hi All,

I have a list of hostnames in a text file and I would like to craft a bash script that would group them for use with pdsh.

For example... I would like to group the following from a file:

Code:
hostname1000
hostname1001
hostname1002
hostname1003
hostname1004
hostname2000
hostname2001
hostname2002

into hostname[1000-1004,2000-2002]

I tried some prelimenary scripts like:

Code:
num=1;for a in $(cat range_hostname.txt |cut -c 1-12 |sort) ; do echo ${a}${num}; num=$[num+1 ];done

to get hostname10, for example, and put a count after, but this just counts all the lines and puts the count at the end. Not like a group of like names like I need.

Any ideas for this?

Thanks!
Joe

Locale::Currency(3pm)					 Perl Programmers Reference Guide				     Locale::Currency(3pm)

NAME
Locale::Currency - standard codes for currency identification SYNOPSIS
use Locale::Currency; $curr = code2currency('usd'); # $curr gets 'US Dollar' $code = currency2code('Euro'); # $code gets 'eur' @codes = all_currency_codes(); @names = all_currency_names(); DESCRIPTION
The "Locale::Currency" module provides access to standard codes used for identifying currencies and funds, such as those defined in ISO 4217. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 4217 three-letter codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying currencies. A code set may be specified using either a name, or a constant that is automatically exported by this module. For example, the two are equivalent: $curr = code2currency('usd','alpha'); $curr = code2currency('usd',LOCALE_CURR_ALPHA); The codesets currently supported are: alpha, LOCALE_CURR_ALPHA This is a set of three-letter (uppercase) codes from ISO 4217 such as EUR for Euro. Two of the codes specified by the standard (XTS which is reserved for testing purposes and XXX which is for transactions where no currency is involved) are omitted. This is the default code set. num, LOCALE_CURR_NUMERIC This is the set of three-digit numeric codes from ISO 4217. ROUTINES
code2currency ( CODE [,CODESET] ) currency2code ( NAME [,CODESET] ) currency_code2code ( CODE ,CODESET ,CODESET2 ) all_currency_codes ( [CODESET] ) all_currency_names ( [CODESET] ) Locale::Currency::rename_currency ( CODE ,NEW_NAME [,CODESET] ) Locale::Currency::add_currency ( CODE ,NAME [,CODESET] ) Locale::Currency::delete_currency ( CODE [,CODESET] ) Locale::Currency::add_currency_alias ( NAME ,NEW_NAME ) Locale::Currency::delete_currency_alias ( NAME ) Locale::Currency::rename_currency_code ( CODE ,NEW_CODE [,CODESET] ) Locale::Currency::add_currency_code_alias ( CODE ,NEW_CODE [,CODESET] ) Locale::Currency::delete_currency_code_alias ( CODE [,CODESET] ) These routines are all documented in the Locale::Codes::API man page.
