How to compare two String Time
I am trying to compare two string time to figure out the difference.

I need to find out the start date of a process is running for over certain minutes.

so far I was able to get the process start time and system time. Now I need to figure out the difference between two time in minutes.

Here is my code so far: batch_output_x is the process i am trying to see if its running over certain minutes or not.

Code:
#!/usr/bin/ksh

. ~/gateway/bin/gateway_env.sh

VAR=$(ps -ef | grep batch_output_x )

        FTP_HOUR=$(echo $VAR|cut -c23-24)
        FTP_MIN=$(echo $VAR|cut -c26-27)
        FTP_SEC=$(echo $VAR|cut -c29-30)

    FTP_HOUR_MIN_SEC=$FTP_HOUR:$FTP_MIN:$FTP_SEC
    RUN_TIME=`date +'%H:%M:%S'`

Now how do i get the time difference in minute?

if i do echo on FTP_HOUR_MIN_SEC and RUN_TIME this is what i get.
Code:
RUN_TIME=09:28:23
FTP_HOUR_MIN_SEC=09:28:23



---------- Post updated at 10:00 AM ---------- Previous update was at 09:36 AM ----------

I am trying to convert the times into second and then compare with this code
Code:
FTP_H_SEC = (($FTP_HOUR*24)*60+$FTP_MIN)*60+$FTP_SEC

But I get an error. to figure out the bug I separated the calculation
Code:
FTP_HOUR_SEC = $FTP_HOUR*24
    FTP_MIN_SEC    = $FTP_HOUR_SEC*60+$FTP_MIN
    FTP_H_SEC = $FTP_MIN_SEC*60+$FTP_SEC

    echo FTP_SEC=$FTP_H_SEC

but this is the out put i am getting

Code:
./chk_process.sh[27]: FTP_HOUR_SEC:  not found
./chk_process.sh[28]: FTP_MIN_SEC:  not found
./chk_process.sh[29]: FTP_H_SEC:  not found

locale::codes::langext

Locale::Codes::LangExt(3)				User Contributed Perl Documentation				 Locale::Codes::LangExt(3)

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

       code2langext ( CODE [,CODESET] )
       langext2code ( NAME [,CODESET] )
       langext_code2code ( CODE ,CODESET ,CODESET2 )
       all_langext_codes ( [CODESET] )
       all_langext_names ( [CODESET] )
       Locale::Codes::LangExt::rename_langext  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangExt::add_langext  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangExt::delete_langext  ( CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangExt::delete_langext_alias  ( NAME )
       Locale::Codes::LangExt::rename_langext_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::add_langext_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangExt::delete_langext_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
