If you want to remove the entire line containing that string, the
Code:
cp file file.backup
cat file | grep -v "http://bushby.mis.amat.com:12440"  > file.new

cat is useless.Smilie

And in this case, maybe fgrep is more suitable.

Code:
fgrep -v "http://bushby.mis.amat.com:12440" infile

by sed with -i option, you can update the infile directly.

Code:
sed -i '/"http:\/\/bushby.mis.amat.com:12440"/d' infile

Then you need backup your file, before update it .

Code:
sed -i`date +%Y%m%d` '/"http:\/\/bushby.mis.amat.com:12440"/d' infile
