Recursively search the string from a column in no. of files
i have a file named keyword.csv(contains around 8k records) which contains a no. of columns.
The 5th column contains all the keywords.
I want to recursively search these keywords in all .pl files(around 1k) and display the filename....Afterthat i will use the filename and some of the column from the keyword.csv to update the database.

I am using below code...but it is not working as keyword.csv contains a no of columns...

find . -type f -name "*.pl" | xargs fgrep -f keyword.csv

Could you please let me know how to handle it.
Thank you in advance.

keyhead

keyhead(1)						      General Commands Manual							keyhead(1)

Name
       keyhead - Change FITS or IRAF header keyword names

Synopsis
       keyhead [-hknv] <FITS or IRAF file> kw1=kw1a kw2=kwd2a ... kwn=kwdna

Description
       Change the names of keywords in FITS or IRAF image headers.  Each current image keyword whose entry is to be modified should be followed by
       an equal sign and a second keyword, with no intervening spaces.	If the -r option is used, the value of the second keyword is transfered to
       that  of the first. Otherwise, the name of the first keyword is changed to the second keyword.  To change keywords in a list of files, sub-
       stitute @<listfile> for the file names on the command line.  To change a lot of keywords, put them, one pair separated by an = sign with no
       spaces  per  line, in a file and substitute @<keylistfile> on the command line.	If two @ commands are present, the program will figure out
       which contains file names and which contains keywords.  Lines in a keyword list file which do not contain an = are ignored.

Options
       -h     Write HISTORY line into output header with sethead version, current date and time, and names of keywords set.

       -k     Write KEYHEAD keyword into output header with the keyhead version, current date and time, and names  of  keywords  whose	names  are
	      changed.	If a KEYHEAD keyword already exists, move the old value to a HISTORY line before writing the new value

       -n     Write a new file with an added "e" before the extension.

       -r letter
	      Replace  value of 1st keyword with value of 2nd keyword instead of changing the name of the 1st keyword to the 2nd keyword.  The 2nd
	      keyword remains in the header.  If the 1st keyword does not exist in the header, it is created.

       -v     Print confirmations of each keyword change.
