If you might ever have cases where some of your script's arguments contain IFS characters, you'll need to use:
instead of:
And, note that processing arguments in a function (using local variables) makes those variables invisible to the calling script. If you intend to invoke callme and then use $file_in in your main script after callme returns; it won't work. (1st because your function exits instead of returning and 2nd because you're using local variables that do not exist outside the function.)
One might also wonder why you would have a utility that has one, and only one, option and that option is not optional, but is instead required to be present. Why not just treat it as an operand instead of an option? The then processing is much simpler:
As a system administrator. sometimes we see the users are trying some commands dangerous for the system health and remove them from their individual coomand history file.
How it is possible to enforce that the normal usres will will not be able to modify the history.
Thanks in advance.

Hi All,
How to enforce all users to change their password when they try to login.

Even it would be much better if anyone can say to enforce all users to change their password next morning they login.
Thanks in advance,

Locale::Codes::LangFam(3pm) Perl Programmers Reference Guide Locale::Codes::LangFam(3pm)NAME
Locale::Codes::LangFam - standard codes for language extension identification
SYNOPSIS
use Locale::Codes::LangFam;
$lext = code2langfam('apa'); # $lext gets 'Apache languages'
$code = langfam2code('Apache languages'); # $code gets 'apa'
@codes = all_langfam_codes();
@names = all_langfam_names();
DESCRIPTION
The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
ISO 639-5.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
language family codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying language families. 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 = code2langfam('apa','alpha');
$lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);
The codesets currently supported are:
alpha
This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.
This is the default code set.
ROUTINES
code2langfam ( CODE [,CODESET] )
langfam2code ( NAME [,CODESET] )
langfam_code2code ( CODE ,CODESET ,CODESET2 )
all_langfam_codes ( [CODESET] )
all_langfam_names ( [CODESET] )
Locale::Codes::LangFam::rename_langfam ( CODE ,NEW_NAME [,CODESET] )
Locale::Codes::LangFam::add_langfam ( CODE ,NAME [,CODESET] )
Locale::Codes::LangFam::delete_langfam ( CODE [,CODESET] )
Locale::Codes::LangFam::add_langfam_alias ( NAME ,NEW_NAME )
Locale::Codes::LangFam::delete_langfam_alias ( NAME )
Locale::Codes::LangFam::rename_langfam_code ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangFam::add_langfam_code_alias ( CODE ,NEW_CODE [,CODESET] )
Locale::Codes::LangFam::delete_langfam_code_alias ( CODE [,CODESET] )
These routines are all documented in the Locale::Codes::API man page.
