How to get all the lines after a matching word till the next different matching word?
For example, my input looks like below.
1 2 3 5 6
and I need to
sed from 1 to 5 and in my output I need to include 1 but I do not want to include *5*and the remaining lines.
If my file contains no 5, I need to do have the remaining lines till the end.
NOTE: I saw the referenced link that looks like a duplicate to my question, titled: Show only text between 2 matching pattern but it doesn't answer my question. The answers there didn't include a way to handle if the secondmatch isn't in the file.
