Hi
awk it's not best for this job.
For replace charecter - generaly use tr or sed
Example on awk:
awk -F<old_char> ' { for (i=1; i<NF ;i++ ) printf ( "%s<new_char>", $i ); print $NF }' <file>
#Replace "e" on "a" in /etc/hosts
awk -Fe ' { for (i=1; i<NF ;i++ ) printf ( "%sa", $i ); print $NF }' /etc/hosts
Regards.
PS. Same on *tr"
cat file | tr "e" "a"

How to remove a character in a file??
I'm not getting how to remove a character from a file.Could anyone post a method to do this?Any help would be appreciable.
Ohhh... and one more thing... unless you're really unlucky, a few "extranious trailing nulls" won't make a jot of difference to the size of the file on disk, each each file "fills" whole blocks anyway, which is 1K (I think) on both fister and *nix... unless of course we're talking "lots" of trailing-nulls, or lots-and-lots of files.

Hello pf1tarac, I don't believe that is possible. In order to create a PDF file, you would need Adobe Acrobat or some other PDF compatible product to save a scan to the PDF format.
There are some free PDF programs available. Here is a link to one of them.
