What command can replace grep -A?

Question

linux

It is necessary to display the description of the --color key from man ls. The teacher said to use man ls | grep - - '- -color' . But then the description is not displayed. What can replace grep-A with?

Answer 1

and why -A needs to be replaced? why not add?

Answer 2

man ls | less +/color

Answer 3

man ls | grep -A 1 "\-\-color\[=WHEN\]"

-A 1- after 1 line after found
'\-\-color\[\=WHEN\]'- escape special characters
Now you can either cut off show 1 line from the end or
man ls | grep -A 1 "\-\-color\[=WHEN\]" | tail -n1
tail - n1

man ls | grep -A 1 "\-\-color\[=WHEN\]" | grep -v =WHEN

-v negation
But if the task is more serious, for example, the description can be more than one line of two or a fixed number, then you need to do it differently grep here, not the awk helper, everything is yours because it supports both regular expressions and multiline and conditions;)
as an option, you can find out in mana where the ls mana file is located and parse data from it
