Top Forums UNIX for Beginners Questions & Answers How to have local shell variables in a ksh script seen on remove server in SSH block? Post 303036275 by DJR on Friday 21st of June 2019 09:18:45 AM

Thanks but these don't work. Escaping the variables with a backslash does nothing - tried in double quotes also as in \"$var" and either way they are still blank in the SSH block. If I just say
Code:
fn=\$filename 
or
fn=\"$filename"

and then echo $fn right afterwards either way it is blank.

I'm not really sure what you are trying to show in the second one. Yes I can declare a variable within the SSH part and use it there, but that doesn't help me. I need to be able to reference the variables I declared before I accessed the remote server.

I've been playing around with it some more and here is something I've found that really stumps me. As I said, escaping it with the backslash does nothing. However if I use double quotes ONLY, it does, sort of:

If I say within the SSH block,
Code:
echo fp = $\filepath

It returns nothing: fp =

However if use doublequotes:
echo fp = "$filepath"

This works, it displays fp = /xxx/yyy/zzz/

However, it still won't assign it to a local variable or work in an expression. So if I try this:
Code:
echo fp = "$filepath"
fp="$filepath"
echo fp = $fp

I get

Code:
fp = /xxx/yyy/zzz/
fp =

Why is it that i can evaluate it in the echo statement but it won't assign it to the remote variable?

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.
