I have two files like below:
file1
"Connect" CONNECT_ID="12"
"Connect" CONNECT_ID="11"
"Connect" CONNECT_ID="122"
"Connect" CONNECT_ID="109"
file2
"Quit" CONNECT_ID="12"
"Quit" CONNECT_ID="11"
The file contents are not exactly same but similar to above and the number of records are minimum 100,000.
Now i want to get the result as show below into file1 (means the final result should be there in file1)
"Connect" CONNECT_ID="122"
"Connect" CONNECT_ID="109"
I have used a while loop something like below:
awk {'print $2'} file2 | sed "s/CONNECTION_ID=//g" > sample.txt
while read actual; do
grep -w -v $actual file1 > file1_tmp
mv -f file1_tmp file1
done < sample.txt
Here I have adjusted my code according to example. So it may or may not work.
My problem is the loop is repeating for more than 1 hour to complete the process.
So can any one suggest me how to achieve the same with any other ways like using diff
or comm
or sed
or awk
or any other linux command which will run faster?
Here mainly I want to eliminate this big typical while
loop.
