Grep a pattern given in one file at other file and display its corresponding contents as output.
*****************************************
Right now i have this current system.

I have two files say xxx.txt and yyy.txt. xxx.txt is with list of patterns within double quotes. Eg.
Code:
"this is the line1"
"this is the line2"

The yyy.txt with lot of lines. eg:
Code:
"This is a test message which contains rubbish information just to fill the page which is of no use. this is the line1 which is suppose to be grepped and displayed as a output."

My output is to search the pattern given in xxx.txt at yyy.txt and display the corresponding line as output.

Eg output: this is the line1 which is suppose to be grepped and displayed as a output.

The following script does this.(thanks rdcwayx for giving this solution)
Code:
awk -F \" 'NR==FNR {a[$2];next} {for (i in a) if ($0 ~ i) print }'  xxx.txt yyy.txt

*****************************************

My proposed system is as follows.

eg:

I have two files say aaa.txt and bbb.txt.

aaa.txt with list of patterns in double quotes and its corresponding output which has to be displayed.
Code:
"this is the line1"=line one found
"this is the line2"=line two found

bbb.txt with lot of lines. eg:
Code:
"This is a test message which contains rubbish information just to fill the page which is of no use.
 this is the line1 which is suppose to be grepped and displayed as a output."

my requirement is to search the pattern given in double quotes in aaa.txt at bbb.txt and if it exists in bbb.txt, the corresponding pattern after = sign in aaa.txt should be displayed.

Eg output: line one found

Please let me know if i am not clear.

ecaccess-file-move

ECACCESS-FILE-MOVE(1p)					User Contributed Perl Documentation				    ECACCESS-FILE-MOVE(1p)

NAME

       ecaccess-file-move - Move or Rename ECaccess Files

SYNOPSIS

       ecaccess-file-move -version|-help|-manual

       ecaccess-file-move [-debug] source-ecaccess-file target-ecaccess-file

DESCRIPTION

       Allow moving an ECaccess File. When the move occurs within the same ECaccess File System then it is a rename. When the move occurs across
       two different ECaccess File Systems then first a copy is done and then a delete of the original file is done (e.g. similar to ecaccess-
       file-copy ... -erase).

       The source-ecaccess-file and target-ecaccess-file are in the form [domain:][/user-id/]path. Please read the "Shell commands -> File
       Management" section of the "ecaccess" guide for more information on the ECaccess File System.

ARGUMENTS

       source-ecaccess-file
	       The source ECaccess File name.

       target-ecaccess-file
	       The target ECaccess File name.

OPTIONS

       -version
	       Display version number and exits.

       -help   Print a brief help message and exits.

       -manual Prints the manual page and exits.

       -debug  Display the SOAP messages exchanged.

EXAMPLES

       ecaccess-file-move ec:test1.txt ec:test2.txt

       Rename the test1.txt file in the ECFS directory of the authenticated user in test2.txt.

       ecaccess-file-move ec:test1.txt home:test2.txt

       Copy the test1.txt file from the ECFS directory of the authenticated user to the test2.txt file in the $HOME directory of the authenticated
       user, then delete the test1.txt file from ECFS.
