I have text file like (the specific part of the whole file);
! lat long elev (m)
! 44.5199005 11.6468000 50.4276
I need to extract second line and save them in another text file. The numbers are variable and "!" syntax is also exist several times in the text. For the first line there is always 8 spaces between "!" and "lat" but this is not the case for the second line. Is there any command available to allow me to extract next line after grep "! lat" text
Best Answer
You can use
grep -A1 'expression'
From the manual:
In your case:
should work to extract the second line only.
Note:
You can use
grep -P '^! {8}lat'
instead of typing many. This is less error prone. The
-P
flag enables perl style regular expressions and{8}
(There is a space before the '{') matches exactly 8 spaces.
