Handling Parameters in Perl
Hi All,

I'm pretty new to the forum and also to UNIX. I have a requirement for which I need some help. I have a script (example.script) where I get user inputs using the read command. I would need to pass the read-fetched input to a perl command (explained below) in my script. The part which confuses me is that the input has characters like / and . which has to manipulated. Please help me on the same. Below are the files.

test.file: (Current)
--------
Code:
 
-
-
.LOGON SERVER/userid,password;
-
-

test.file: (Expected)
--------
Code:
 
-
-
.RUN FILE /home/user/my.test.logon;
-
-

example.script:
--------------
Code:
 
echo " Please enter the path to the LOGON file: \c"
read logon
 
perl -p -i -e "s/^\.LOGON.*$/.RUN FILE $logon;/g" test.file

I execute the example script as:
Code:
 
$ ksh example.script
 Please enter the path to the LOGON file: /home/user/my.test.logon

While running the above code, I am getting the below error message:

Quote:
Bareword found where operator expected at -e line 1, near "s/^\.LOGON.*$/.RUN FILE /home"
syntax error at -e line 1, near "s/^\.LOGON.*$/.RUN FILE /home"
Search pattern not terminated at -e line 1.
I hope this is because of using characters / and . in the input string without escape sequences (\). But basically I want input to be entered without escape characters, like in /home/user/my.test.logon, as it will be entered by all users. Is there a way in UNIX where I can have the input entered as-is and still I will be able to format the input before parsing it?

Any help on this is greatly appreciated.

Thanks in Advance. Let me know for any questions.

locale::script

Locale::Script(3)					User Contributed Perl Documentation					 Locale::Script(3)

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::delete_script  ( CODE [,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.
