sed to delete lines from a file by using wildcard
I have a text file with tons of data and I want to remove all lines which are have "240" regardless of ABC or BCD and shouldnt delete anything else

Code:
ABC_10_00024045.zip blah blah ABC_10_00024045.zip.new
ABC_10_00024046.zip blah blah ABC_10_00024046.zip.new
ABC_10_00024446.zip blah blah ABC_10_00024446.zip.new
ABC_10_00024244.zip blah blah ABC_10_00024244.zip.new
BCD_10_00024045.zip blah blah BCD_10_00024045.zip.new
BCD_10_00024046.zip blah blah BCD_10_00024046.zip.new
EFG_10_00024144.zip blah blah EFG_10_00024144.zip.new
AMM_10_00024232.zip blah blah AMM_10_00024232.zip.new
BCD_10_00024047.zip blah blah BCD_10_00024047.zip.new


so output file should be
ABC_10_00024446.zip blah blah ABC_10_00024446.zip.new
ABC_10_00024244.zip blah blah ABC_10_00024244.zip.new
EFG_10_00024144.zip blah blah EFG_10_00024144.zip.new
AMM_10_00024232.zip blah blah AMM_10_00024232.zip.new

Code:
sed '/240/d' infile

Most simple:
Code:
grep -v '240' in.file

More specific:
Code:
egrep -v '[0-9]{3}240[0-9]{2}' in.file
