Hi Pradhikshan

Any attempts from your side yet?
If not, to get you started, start playing around with these: (please do required changes yourself, eg: Desktop)

I'm not familiar with ksh, but these bash basics should work fine:
Code:
cd Desktop
ls
echo *
for this_file in *
do
	echo "$this_file"
	echo "more commands of yours"
	ls -l "$this_file"
done

SEARCH="this pattern"
grep --color=auto "$SEARCH" *
echo "$SEARCH" | sed s,"$SEARCH","new stuff",

If the following output pleases you, prefix '*' with -i
Code:
sed s,"$SEARCH","new stuff", *

Hope this helps

drop_text_search_dictionary

DROP TEXT SEARCH 
DICTIONARY(7)					   SQL Commands 				    DROP TEXT SEARCH DICTIONARY(7)

NAME

       DROP TEXT SEARCH DICTIONARY - remove a text search dictionary

SYNOPSIS

       DROP TEXT SEARCH DICTIONARY [ IF EXISTS ] name [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP TEXT SEARCH DICTIONARY drops an existing text search dictionary. To execute this command you must be the owner of the dictionary.

PARAMETERS

       IF EXISTS
	      Do not throw an error if the text search dictionary does not exist.  A notice is issued in this case.

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

       CASCADE
	      Automatically drop objects that depend on the text search dictionary.

       RESTRICT
	      Refuse to drop the text search dictionary if any objects depend on it.  This is the default.

EXAMPLES

       Remove the text search dictionary english:

       DROP TEXT SEARCH DICTIONARY english;

       This  command  will not succeed if there are any existing text search configurations that use the dictionary. Add CASCADE to drop such con-
       figurations along with the dictionary.

COMPATIBILITY

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

SEE ALSO

       ALTER TEXT SEARCH DICTIONARY [alter_text_search_dictionary(7)], CREATE TEXT SEARCH DICTIONARY [create_text_search_dictionary(7)]
