Have you tried something like this ?
sed -e '/"\*one;twothree.*FOO/b' -e'/"\*one;twothree/s/ /FOO /' foo.txt



Hope This Helps, PH.

Hi,
Try and it doesn't work. Please help

linuxbuild : /home/hb >more test.sh
#!/bin/sh
sed -e '/"\*one;twothree.*FOO/b' -e'/"\*one;twothree/s/ /FOO /' foo2.txt

linuxbuild : /home/hb >more foo2.txt
hb
test
*one;twothree

linuxbuild : /home/hb >./test.sh
hb
test
*one;twothree
linuxbuild : /home/hb >

No need of the " in the pattern ?
So, you may try this:
sed -e '/\*one;twothree.*FOO/b' -e'/\*one;twothree/s/ /FOO /' foo2.txt
