Full Discussion: Error when executing script
Operating Systems Linux Red Hat Error when executing script Post 302996992 by anaigini45 on Friday 5th of May 2017 05:03:25 AM

I have another question on command substitution.
The same script, but different command substitution.

I simply run this command from the terminal :

Code:
[root@L28tstream1 emokheng]# stat -c %z * | awk '{print $1}'
2015-08-18
2015-08-18
[root@L28tstream1 emokheng]#

As you see, I get the dates of the file generated in the directory.

However, when I attempt to use this command as a substitute, like this, I get a diferent output :

Code:
[root@L28tstream1 emokheng]# D=$(stat -c %z * | awk '{print $1}')
[root@L28tstream1 emokheng]# echo $D
2015-08-18 2015-08-18

It all displays in one line. Why is this, and how do I get it to display in two separate lines like the command above this?

Actually the main output I want is to get ONLY the day section of the whole date. Means I want to extract only '18' from 2015-08-18. This is for all the files in the directory.
Therefore, I use this command :

Code:
[root@L28tstream1 emokheng]# FDAY=$(date -d "$D" '+%d')
date: invalid date `2015-08-18\n2015-08-18'
[root@L28tstream1 emokheng]#

However, as you can see, the error is shown. Perhaps if
Code:
echo $D

displays two separate lines, the error above will not happen?

How do I display ONLY the day part of the whole date for a file in a directory?

locale::codes::langext5.18

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.
