sed for string in each file

[milage]

Hi,

Say I have a directory of files each with a header which looks like this:

#
# $RCSfile: MF.form,v $
# $Author: david $
# $Revision: 1.46.2.6.2.3.2.4 $
#

I want to extract from each file into a variable the long revision number between "$Revision: " amd " $" at the end of the line.

I assume I want to use sed for this but i'm not sure how and I'd prefer not to have to go into a perl script, however, if that is the only way then just say as I can do it myself.

Cheers

Rob

for file in myFiles*
do
sed -n -e 's/.*\$Revision:[^0-9]*\([0-9.][0-9.]*\).*/\1/p' ${file}
done

Rob:

Using sed is the best, most obvious answer, but you can use tr:

var=`egrep &quot;Revision:&quot; file| tr -dc .0123456789`
echo $var
