How to select lines between two marker patterns which may occur multiple times with awk/sed

Question

Using awk or sed how can I select lines which are occurring between two different marker patterns? There may be multiple sections marked with these

Answer 1

From the previous response's links, the one that did it for me, running ksh on Solaris, was this:

sed '1,/firstmatch/d;/secondmatch/,$d'

• 1,/firstmatch/d: from line 1 until the first time you find firstmatch, delete.
• /secondmatch/,$d: from the first occurrance of secondmatch until the end of file, delete.
• Semicolon separates the two commands, which are executed in sequence.
