One, using sed's pattern matching with the "d" (delete) clobbers whole lines, as you noted. The solution would seem to to use the "s" (substitute) form instead: <code> sed 's/WORD1.*WORD2//g' input.txt </code> BUT then you discover the larger problem: sed by default does all it's processing one line at a time (e.g., it fills it's processing buffer up to each '\n' it encounters). The formal approaches include using sed's "hold space" and "pattern space" commands, N, H/h,G/g,x as hinted here: http://www.gnu.org/software/sed/manual/html_node/Other-Commands.html I used that route in an email formatting script, but these days if i can get away with quick'n'dirty, i try to just strip all occurrences of '\n' from the stream you give sed like this: <code>cat input.txt | tr -d '\n' | sed 's/WORD1.*WORD2//g' </code> No files i've worked on are big enough to blow sed's buffer so far.
