Isn't there a way to get sed to look at more than one line at a time for a regex value --> sed '/regex/M, /xyz/,/do something' ???
Yes , just everytime there is a change in sed but sometimes use sed can be difficult to others (awk,perl,,,).and and you can use atpresent methods,functions in the others..there are may some difficults especially contain same number or same alpha character line in which method your want (between lines method)
but we write specific sed script for this
however you said sed '/regex/M, /xyz/,/do something' --> sed cant know what value would process for this you must give specific values for example
for exa
the code if "cn: kyu" and "cn: jzaragoza" between lines if contains two DIR lines (for more lines a maybe can a write specific script -> like for 3 lines N;N;N or we find line number between our values and then set a value for this [x=N;N;N;] and then use "$x" instead of values ...... )
or can write with hold buffer
