SED to search for and delete ip with a partial match
Solution 1:
Thank you for your help.
Alas none of the above suggestions would work for me.
After much reading and experimentation
I found had to add the -r (to activate the regex) before the -i and this is the format I used for the regex, which seems to work.
sed -r -i '' '/^120[.]152[.][0-9]{1,3}[.][0-9]{1,3}/d' /path/to/some/file
to remove the ip 120.152.35.192 from the file "file"
I tested the regex on the "The Regedx Coach" it seems valid.
However I would welcome any additional input and suggestions to refine the above.
Regards
