I have a large file and I want to print the lines that do not match a particular undesired pattern. The following does the exact opposite of what I want, namely it retains all the undesirable lines.
grep -e '\[0.0, 0.0\]' locscore.txt
How can I get the lines that DON'T have the above pattern? I tried
grep -e '^*(?!\[0.0, 0.0\])*$' locscore.txt
but it produces nothing.

if you use grep, there is an option -v
, it does what you need.
from man page:
-v, --invert-match
Invert the sense of matching, to select non-matching lines. (-v is specified by POSIX.)
