I have a file with the following contents:



Windows user
I love windows
Windows 10
# I like it
# I want to keep these two lines
Just started with my job
New to shell scripting as well
New to Mac
Please help!

#EOF


I want to delete all the lines:



starting from "I love windows" to "New to shell scripting as well", but keep the comments that are present between these lines.



So, the desired output should appear as below:



Windows user
# I like it
# I want to keep these two lines
New to Mac
Please help!

#EOF


I used sed command to delete the range of lines using the line numbers



sed '2,7d' file


But this command deletes the comments as well, which I want preserved.

Try using:



sed '2,7/^[[:blank:]]*#/!d' infile


This is normally deleting lines from 2~7 but not the lines that starts with a hash as known as a commented line.



The [[:blank:]] character class is used to match and keep those lines that it's a commented line but took whitespaces at behind too either zero or more whitespace.



To be more specifically using the patterns given:



sed '/I love windows/,/New to shell scripting as well/ /^[[:blank:]]*#/!d' infile


Standard-complaint sed solution would be:



sed -e '2,7' -e '/^[[:space:]]*#/!d' -e '' infile


The output is:



Windows user
# I like it
# I want to keep these two lines
New to Mac
Please help!

#EOF

One-line joke

A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
