And you need tell use your expect O/P

for example, for this string: /TEXT123/TEXT456/ABC123/

what will be TEXT and ABC?

Seems basename and dirname will help you.

---------- Post updated at 11:00 AM ---------- Previous update was at 10:55 AM ----------

Code:
cat infile |while read LINE; 
do  
  TEXT=$( echo $LINE|awk '{gsub(/"/,"");print $2}' |xargs dirname)
  ABC=$(echo $LINE|awk '{gsub(/"/,"");print $2}' |xargs basename)
done

Code:
"READ /TEXT123/ABC123"
TEXT= TEXT123
ABC= ABC123

"READ TEXT123/ABC123/"
TEXT= TEXT123
ABC= ABC123

"READ /TEXT123/TEXT456/ABC123/"
TEXT= TEXT123/TEXT456
ABC= ABC123

Oh you prolly misunderstood the " " part in my text examples, basically my script gets executed by another one and that script is passing two arguments where the first one contains my examples... so there arn't any real "" in the text... $1 = READ /TEXT123/ABC123

alter_text_search_dictionary

ALTER TEXT SEARCH 
DICTIONARY(7) 			  PostgreSQL 9.2.7 Documentation			   ALTER TEXT SEARCH DICTIONARY(7)

NAME

       ALTER_TEXT_SEARCH_DICTIONARY - change the definition of a text search dictionary

SYNOPSIS

       ALTER TEXT SEARCH DICTIONARY name (
	   option [ = value ] [, ... ]
       )
       ALTER TEXT SEARCH DICTIONARY name RENAME TO new_name
       ALTER TEXT SEARCH DICTIONARY name OWNER TO new_owner
       ALTER TEXT SEARCH DICTIONARY name SET SCHEMA new_schema

DESCRIPTION

       ALTER TEXT SEARCH DICTIONARY changes the definition of a text search dictionary. You can change the dictionary's template-specific options,
       or change the dictionary's name or owner.

       You must be the owner of the dictionary to use ALTER TEXT SEARCH DICTIONARY.

PARAMETERS

       name
	   The name (optionally schema-qualified) of an existing text search dictionary.

       option
	   The name of a template-specific option to be set for this dictionary.

       value
	   The new value to use for a template-specific option. If the equal sign and value are omitted, then any previous setting for the option
	   is removed from the dictionary, allowing the default to be used.

       new_name
	   The new name of the text search dictionary.

       new_owner
	   The new owner of the text search dictionary.

       new_schema
	   The new schema for the text search dictionary.

       Template-specific options can appear in any order.

EXAMPLES

       The following example command changes the stopword list for a Snowball-based dictionary. Other parameters remain unchanged.

	   ALTER TEXT SEARCH DICTIONARY my_dict ( StopWords = newrussian );

       The following example command changes the language option to dutch, and removes the stopword option entirely.

	   ALTER TEXT SEARCH DICTIONARY my_dict ( language = dutch, StopWords );

       The following example command "updates" the dictionary's definition without actually changing anything.

	   ALTER TEXT SEARCH DICTIONARY my_dict ( dummy );

       (The reason this works is that the option removal code doesn't complain if there is no such option.) This trick is useful when changing
       configuration files for the dictionary: the ALTER will force existing database sessions to re-read the configuration files, which otherwise
       they would never do if they had read them earlier.

COMPATIBILITY

       There is no ALTER TEXT SEARCH DICTIONARY statement in the SQL standard.
