Using sed to delete multiple lines matching different patterns,

sed '/value1\|value2/\|value3/d' filename > newfilename    - is this correct?

After correcting the little typo you made it might work, but not all sed implementations support it:

sed '/value1\|value2\|value3/d' filename > newfilename  

If it doesn't work try this:

sed '/value1/d;/value2/d;/value3/d' filename > newfilename

Some rather exotic versions of sed do not even support the second suggestion above.

In this case try:

sed -e '/value1/d' -e '/value2/d' -e '/value3/d' filename > newfilename

I'd use grep

grep -Ev "value1|value2|value3" filename >newfilename
