Gentle readers: A clarifiction to my previous posting. I need an sed line (or some gory pipeline) to extract the data between BEGIN and END. I should have added the following: >I have a text file of this form: [... junk ...] > BEGIN > 1 > 2 > 3 > END [... junk ...] > BEGIN > 4 > 5 > 6 > END [... junk ...] Add to that the fact that the data between BEGIN...END is really not plain sequential numbers; it is random text. Sorry I was not more clear. If you have a SED line to deal with the above, I would love to see it. Thanks. -- _______________________________________________________________________________ Rodrigo Murillo, University of Colorado - Boulder (303) 761-0410 murillo@boulder.colorado.edu | ..{ncar|nbires}!boulder!murillo ( Machines have less problems.

Your basic problem is that you have state in your text file (in,out), and the state changes only on subsequent lines. It is difficult (probably not impossible) to write a sed script, though an awk script is trivial. Try: awk ' /^BEGIN$/ { state = "in"; next } /^END$/ { state = "out"; next } { if (state == "in") print $0 } ' < yourfile -- --------------------"Well, it looked good when I wrote it"--------------------- Verbal: Dave Burton Net: ...!ihnp4!laidbak!daveb V-MAIL: (312) 505-9100 x325 USSnail: 1901 N.

How about
sed '/BEGIN/,/END/p
d' files...
in sh or ksh or
sed '/BEGIN/,/END/p\
d' files...
in csh? These lines will include the BEGIN and END in the output, but will
strip all other lines.
I'd prefer to use awk:
awk '/BEGIN/,/END/' files...
papillo the awkward

Here's a script that seems to work: (to be run as: sed -n -e script) ----------------------------------------------------------------------------- s/BEGIN// t nums b : nums n s/END// t p b nums ----------------------------------------------------------------------------- I was going to e-mail but thought this solution is rather kludgy. Does someone have a nice elegant solution? Yes, I know it can be done in awk etc.... -- Shamim Mohamed, Dept. of Computer Science, U of Arizona, Tucson AZ 85721 (602) 621-4891 {ihnp4,allegra,cmcl2...}!arizona!sham | sham@arizona.edu
