Hi,

I have a file which contains the below data. I want to search for a pattern server="http://bushby.mis.amat.com:12440" and remove it from the file.

Please let me know how can i do this.

$ ruby -pne 'gsub(/http:\/\/bushby\.mis\.amat\.com:12440/,"")' file

If you want to remove the entire line containing that string, the

cp file file.backup
cat file | grep -v "http://bushby.mis.amat.com:12440"  > file.new
4 
sed 's|server="http://bushby.mis.amat.com:12440"||g' file
5

cat is useless.:slight_smile:

And in this case, maybe fgrep is more suitable.

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

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

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

Then you need backup your file, before update it .

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