My requirement is the user enter date field should compare the input file

if user enter date as 12.03.2013 it should compare with all date one by one from input file

Code:
12.03.2013 -ne 02.05.2014
12.03.2013 -ne 10.05.2014
12.03.2013 -ne 17.09.2014

if matches it should process else it should throw an error.

I tried the below code

Code:
#!/bin/ksh
echo "Please enter  start date:"
read startdate
#/usr/xpg4/bin/awk -F, '{print $1}' inputfile >> file
if[[${startdate} -ne $(awk -F, '{print $1}' file)]]
then
echo "date is not valid"
fi

the code is not comparing row by row
try this Smilie

Code:
#!/bin/ksh
echo "Please enter  start date:"
read startdate
correctdate=$(echo $startdate|sed 's/[^0-9][^0-9]*/\./g')
awk -vd="$correctdate" '$1==d{print "equal-Line Number " NR;x=1}
END{if(!x)print "date is not valid"}' your.txt

Code:
# ./code
Please enter  start date:
5/5/5
date is not valid

# ./code
Please enter  start date:
10.05.2014
equal-Line Number 2

Locale::Codes::LangExt(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangExt(3pm)

NAME
Locale::Codes::LangExt - standard codes for language extension identification SYNOPSIS
use Locale::Codes::LangExt; $lext = code2langext('acm'); # $lext gets 'Mesopotamian Arabic' $code = langext2code('Mesopotamian Arabic'); # $code gets 'acm' @codes = all_langext_codes(); @names = all_langext_names(); DESCRIPTION
The "Locale::Codes::LangExt" module provides access to standard codes used for identifying language extensions, such as those as defined in the IANA language registry. Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language registry codes will be used. SUPPORTED CODE SETS
There are several different code sets you can use for identifying language extensions. 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: $lext = code2langext('acm','alpha'); $lext = code2langext('acm',LOCALE_LANGEXT_ALPHA); The codesets currently supported are: alpha This is the set of three-letter (lowercase) codes from the IANA language registry, such as 'acm' for Mesopotamian Arabic. This is the default code set. ROUTINES
