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

Long meetings (6-7 hours a day): Being “babysat” by supervisor

Confectionery

Prepared foods made with a lot of sugar or other cabohydrates "Sweetmeat" redirects here. For the racehorse, see Sweetmeat (horse). Not to be confused with Sweetbread. This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
