sed help!

[Bowser325]

I'm trying to edit multiple zone files @ once using sed, but when I run the
below command to replace the numeric string that is on the same line as
string "Serial" I get each digit in the numeric string being replaced by
the 10 digit replacement string.

sed /Serial/s/\[0-9]\/1234567890/g filename

Any help would be appreciated...
Thanks.
Aaron.

Try

sed -e '/Serial/s/[0-9]\{1,\}/12345/g' filename

Thanks a lot. Any chance of getting a brief explanation of the {1,\}?
Thanks.

Please don't top-post.

\{n,m\} means n to m repetitions of the preceeding pattern, in that
case [0-9]. The missing m means that there is no upper limit.

It is very rewarding to read documentation on regular expressions.
They occur frequently in UNIX.
