To use sed effectively, we should be clear about how to define range. Range is typically two addresses in a file as follows:
- Range with numbers:
'6d': range of line 6 '3,6d': range from line 3 to 6
- Range with pattern:
- This will specify the range of all the lines between pattern1 and pattern2. We can even specify the range with a combination of both, that is, '/pattern/,6'. This will specify the range of lines between the pattern and line 6.
As mentioned, we can specify the range as numbers, pattern, or a combination of both, as shown here.
