Issue
I'm trying to learn sed. Whilst trying to learn I entered the following lines in my terminal.
~/tmp>$ cat sedtest
a
sed will enjoy writing over this
I love cats, lovely
b
sed will really really enjoy writing over this
sed will really really hate writing over this
c
~/tmp>$ sed -n '/a/,/b/p' sedtest
a
sed will enjoy writing over this
I love cats, lovely
b
sed will really really enjoy writing over this
sed will really really hate writing over this
c
~/tmp>$
Why does my sed statement print all lines? I expect it to only print in between lines that contain the letters a and b inclusive.
Solution
Change your command to
sed -n '/^a$/,/^b$/p' sedtest
in order to exclude lines containing an a or b somwhere and just match lines that are exactly a or b:
a
sed will enjoy writing over this
I love cats, lovely
b
