Increase sed performance
I'm using sed to do find and replace. But since the file is huge and i have more than 1000 files to be searched, the script is taking a lot of time. Can somebody help me with a better sed command. Below is the details. Input: Code:
1 1 2 3 3 4 5 5 Here I know the file is sorted. My cross reference file will be Code:
1A 2B 3C 4D 5E 6F here also the file will be sorted on the first character. The output I want is Code:
1A 1A 2B 3C 3C 4D 5E 5E |
