Hi there,
I think this was the correct forum. At least it's the one I use.
If your not very familiar with sed, here are some remarks:
1) You can put all the replacements in one sed
Code:
cat addresses.txt | sed -e 's/Ave./Avenue/; s/St./Street/; s/E./East/; s/Ter./Terrace/' > addresses4.txt

2) Without the g option, only the first occurence of the string in each line will be replaced. I know it's not very likely to have "Ave." appear two times in an address, but you'd better be sure
Code:
cat addresses.txt | sed -e 's/Ave./Avenue/g; s/St./Street/g; s/E./East/g; s/Ter./Terrace/g' > addresses4.txt

3) You don't need to cat the file, just give it as an argument
Code:
sed -e 's/Ave./Avenue/g; s/St./Street/g; s/E./East/g; s/Ter./Terrace/g' addresses.txt > addresses4.txt

4) And if you want to replace the file itself, use the i switch
Code:
sed -i 's/Ave./Avenue/g; s/St./Street/g; s/E./East/g; s/Ter./Terrace/g' addresses.txt

5) Beware that a period (.) is a special character that represent any other one. Which means that Aven, Avel, Aved all match Ave. and will be replaced by Avenue. Escape the period to match an actual period.
Code:
sed -i 's/Ave\./Avenue/g; s/St\./Street/g; s/E\./East/g; s/Ter\./Terrace/g' addresses.txt

I hope I helped
Santiago

locale::codes::langfam

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

NAME

       Locale::Codes::LangFam - standard codes for language extension identification

SYNOPSIS

	  use Locale::Codes::LangFam;

	  $lext = code2langfam('apa');		       # $lext gets 'Apache languages'
	  $code = langfam2code('Apache languages');    # $code gets 'apa'

	  @codes   = all_langfam_codes();
	  @names   = all_langfam_names();

DESCRIPTION

       The "Locale::Codes::LangFam" module provides access to standard codes used for identifying language families, such as those as defined in
       ISO 639-5.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 639-5
       language family codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language families. 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 = code2langfam('apa','alpha');
	  $lext = code2langfam('apa',LOCALE_LANGFAM_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of three-letter (lowercase) codes from ISO 639-5 such as 'apa' for Apache languages.

	   This is the default code set.

ROUTINES

       code2langfam ( CODE [,CODESET] )
       langfam2code ( NAME [,CODESET] )
       langfam_code2code ( CODE ,CODESET ,CODESET2 )
       all_langfam_codes ( [CODESET] )
       all_langfam_names ( [CODESET] )
       Locale::Codes::LangFam::rename_langfam  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangFam::add_langfam  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangFam::delete_langfam  ( CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangFam::delete_langfam_alias  ( NAME )
       Locale::Codes::LangFam::rename_langfam_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::add_langfam_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangFam::delete_langfam_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
