Hey friends,
great it worked.
But only one problem is yet to be solved.
I have used following two suggestions given by you

Code:

/usr/bin/tr -d '[:punct:]' < file > file.nospecialchar

and

Code:

/usr/bin/tr -d '[:punct:]' <test>

Its very well working but its replacing special characters by space. I want to remove that space without disturbing other spaces present in file. But special attention is to be given that, it shouldnt even touch other spaces in entire file as it will disturb entire machine readable file. it just have to remove space got generated between DM and CT



e.g.

Code:

DM*&%#^()*%*$|\ / ?CT

expected output

Code:

DMCT

where as existing solution is giving o/p as
DM CT (space is not expected).

Thank you for taking pains.
