Hi,
I want to process a text with script.
The text contains of two regions:
The first region contains of lines beginning with keyword_a
and the second one start with keyword_b.
I want to sort the first region using sort with pattern_a and
after that I want to sort the second region with pattern_b.
I can set the start of the forst sort with
: /keyword_a
in the script. But I dont know how to limit the range of the first
sort so that only lines starting with keyword_a are sorted using
pattern_a. Same goes for the second region...
Try something like
:0/^a/,/^\(a\)\@!/sort
It means loosely:
: - perform an ex command
0 - from before the beginning of the file
/^keyword_a/ - find a line beginning with 'keyword_a'
, - and operate until
/ - we find
^ - the beginning of a line
\(keyword_a\)\@! - where 'keyword_a' doesn't match
/sort - with the sort command
Ben.
