HI Random_Walk, yes you are right about the exact matches, i am just looking for a word that matched in a line of files.

Example of the element that i am looking for in a file

hlkout
[download]

Example of the line that matched the element

     .hlkout(hi_lkout[15:0])
[download]

from the line that matched my regex, i would further do some processing on it, to get something else like for this example i will be using the hi_lkout for another purpose which i dont describe here...
