I am a unix noob. Need some basic help. I have tried using google, but not able to figure this out.

Here are the scenarios:

1. How do I find a directory with a particular name, say "Merlin" in the entire file system? I tried :
Code:
find / -type d -name "dir_name"

The problem is I'm getting thousands of lines, most of them with "blah blah blah...Permission denied".

How can I have only the relevant information, the directory that I am looking for with its path.

2. How do I find a file with name "unicorn", where I do not know it's directory location?
Code:
find . -name "unicorn" -print

.

Same problem, lots of hits with "permission denied".

3. How do I find a file, where I do not know it's location which has a particular pattern inside the file.

This was a bummer. Couldn't find anything. Please help.

1. Correct, you need to be root in order not to have "Permission denied" and search the hole system

2. Same as the first just replace the . with /

3. Find cannot look trough the contents of a file, this can be done with various scripts for example:

Code:
find / -type f | xargs grep "John Smith ID"

This will probaly print thousands of lines if you are not very specific about what you`re searching for, also it will run slow since it have to read every file on your disk. Good advise is at least to remember the directory where the file is.

Code:
man find
man grep
man locate

locale::codes::langvar

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

NAME

       Locale::Codes::LangVar - standard codes for language variation identification

SYNOPSIS

	  use Locale::Codes::LangVar;

	  $lvar = code2langvar('acm');		       # $lvar gets 'Mesopotamian Arabic'
	  $code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langvar_codes();
	  @names   = all_langvar_names();

DESCRIPTION

       The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, 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 variations. 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:

	  $lvar = code2langvar('en','alpha-2');
	  $lvar = code2langvar('en',LOCALE_CODE_ALPHA_2);

       The codesets currently supported are:

       alpha
	   This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian.

	   This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".

	   This is the default code set.

ROUTINES

       code2langvar ( CODE [,CODESET] )
       langvar2code ( NAME [,CODESET] )
       langvar_code2code ( CODE ,CODESET ,CODESET2 )
       all_langvar_codes ( [CODESET] )
       all_langvar_names ( [CODESET] )
       Locale::Codes::LangVar::rename_langvar  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangVar::add_langvar  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangVar::delete_langvar  ( CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangVar::delete_langvar_alias  ( NAME )
       Locale::Codes::LangVar::rename_langvar_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::delete_langvar_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
