Thanks olded, but when i give ur command &quot;sed&quot;
it just displays the changed values in the command prompt
but it doesn't get changed in the original data file. It still remains 0.00. I want to permanently replace 0.00 with 0.25. Can yu help me out please.

Thanks vgersh, but i need to do it in csh only. Any suggestions welcome.

#!/bin/csh
#
# not a really big fan of csh, but......
#
set file='myFile.txt'

ex - &quot;${file}&quot; <<EOF
%s/,0.00/,0.25/g
wq!
EOF vlad
+----------------------------+
| #include<disclaimer.h> |
+----------------------------+

The sed command should be output to another file
and that file is then moved to the current file, like this:

sed &quot;s/0.00/0.25/g&quot; data.file > datafile.tmp
mv datafile.tmp data.file

Another way to do this with perl w/o creating the tmp file is:
perl -p -i -e &quot;s/.00$/.25/g;&quot; datafile

This edits the file in place like the csh 'ex' solution.
