Slow Running Script (Reading 8000 lines)
Slow runnin script. The problem seems to be the sed calls.
In summary the script reads list of users in file1. For each
username search two files (file 1 & file2) for the username
and get the value in the next line after "=". Compare these
values with each other.

If the same then output to a file and if not output to another file.
For approx 8000 lines in file1 it takes approx 15 minutes to run?
not very good. Any suggestions on removing the bottleneck?

Script:
Code:
#!/bin/ksh
compareusernames() {
p_name="$1"
result_one=`sed -n "/$p_name/{n;p;}" $file2 | cut -d= -f2 | tr -d ' '`
result_two=`sed -n "/$p_name/{n;p;}" $file3 | cut -d= -f2 | tr -d ' '`
if [[ "$result_one" = "$result_two" ]] then
        echo "$p_name" >> matches.out
else
        echo "$p_name" >> no_matches.out
fi
 
i=0
while read v_name
do
compareusernames "$v_name"
((i=$i+1))
done < $file1


}

File1:
Code:
user1
user2
user3
user4

File2:
Code:
name=user1
gud=100
name=user2
gud=200
name=user3
gud=300

File3:
Code:
name=user1
gud=100
name=user2
gud=xxx
name=user3
gud=xxx

locale::script5.18

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

NAME

       Locale::Script - standard codes for script identification

SYNOPSIS

	  use Locale::Script;

	  $script  = code2script('phnx');		      # 'Phoenician'
	  $code    = script2code('Phoenician'); 	      # 'Phnx'
	  $code    = script2code('Phoenician',
				 LOCALE_CODE_NUMERIC);	      # 115

	  @codes   = all_script_codes();
	  @scripts = all_script_names();

DESCRIPTION

       The "Locale::Script" module provides access to standards codes used for identifying scripts, such as those defined in ISO 15924.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 15924
       four-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying scripts. 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:

	  $script = code2script('phnx','alpha');
	  $script = code2script('phnx',LOCALE_SCRIPT_ALPHA);

       The codesets currently supported are:

       alpha, LOCALE_SCRIPT_ALPHA
	   This is a set of four-letter (capitalized) codes from ISO 15924 such as 'Phnx' for Phoenician.  It also includes additions to this set
	   included in the IANA language registry.

	   The Zxxx, Zyyy, and Zzzz codes are not used.

	   This is the default code set.

       num, LOCALE_SCRIPT_NUMERIC
	   This is a set of three-digit numeric codes from ISO 15924 such as 115 for Phoenician.

ROUTINES

       code2script ( CODE [,CODESET] )
       script2code ( NAME [,CODESET] )
       script_code2code ( CODE ,CODESET ,CODESET2 )
       all_script_codes ( [CODESET] )
       all_script_names ( [CODESET] )
       Locale::Script::rename_script  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Script::add_script  ( CODE ,NAME [,CODESET] )

       Locale::Script::add_script_alias  ( NAME ,NEW_NAME )
       Locale::Script::delete_script_alias  ( NAME )
       Locale::Script::rename_script_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::add_script_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Script::delete_script_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
