Full Discussion: Why Do You Need the Explicit Pathname to Execute?
Top Forums UNIX for Dummies Questions & Answers Why Do You Need the Explicit Pathname to Execute? Post 302738105 by sudon't on Friday 30th of November 2012 11:04:36 AM

I think people are misunderstanding my question, or I haven't been clear enough. (Or possibly I've misunderstood your answers?) Please forgive my ignorance, I was only wondering why, when you are in the same directory as a file, (not only executables), to access it, you only need its name.
Code:
$ anycommand any_execfile
$ anycommand any_file

But to execute a file, you must add dot-slash.
Code:
$ ./any_execfile

In other words, why doesn't simply typing the name and hitting <ENTER> work?
Code:
$ any_execfile
-bash command not found

Is it perhaps that using the pathname just indicates to the system that execution is your intention? Or that it forces you to do something extra, so you know you are executing something? Yes, that makes sense.


As a side note, I do understand what all of you have been telling me - that executables belong in protected directories, and all the very good reasons for that. I also understand why you encourage me to follow canonical unix protocols - someday I may working on something other than my own Macbook - maybe even a shell account accessed from my own Macbook at home. One should develop good habits.

You can still do so with ./ but it will be hard to claim you did so by accident.
Yes, this is what I was wondering about - the reason it's done this way, is simply that it forces you to realize what you are doing?

locale::codes::langext

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

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.
