Grep behaves diffrent upon printf or echo output
Hello

I want to check whether certain arguments were passed to the script, and when those are, not doing a log entry.
If those arguments are not passed, always do a log entry (*new call*).

What currently i have is this:
Code:
	echo "${@}"|grep -q \\-[Lih] || \
		tui-log -e "$LOG" "\r---- New call $$ ----"

Which upon these 2 commands, produces these lines within the logfiles:
Code:
vhs -h ; vhs -L

With echo i have the expected output:
Code:
21:42:46         Show Help
21:42:46         Show Logfile
21:42:49         Show Help
21:42:49         Show Logfile

However, as soon i change echo to become printf, it produces this (not wanted):
Code:
---- New call 17388 ----
21:44:19         Show Help

---- New call 17423 ----
21:44:19         Show Logfile

In addition i wanted to use [[:space:]]\\-[Lih], but i assume that is another issue?
I've tried quoting the regex, but still fails.

System:
Code:
export LC_ALL=C ; uname -r ; echo "--" ; $SHELL --version
3.16.3-200.fc20.x86_64
--
GNU bash, version 4.2.51(1)-release (x86_64-redhat-linux-gnu)

Any ideas?

When I type a command at the command line it supplies one result and the exact same command in a script egrep '^01|^02|^03|^04' file > fileout count = 29353 same count in the script yields a count of 23492 is there any reason this could be happening. (1 Reply)

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.
