In Perl, something like this would do it:
perl -pi -e 'BEGIN{undef $/;} \
s/ALINE\nANOTHERLINE\nYETANOTHERLINE/ALINE/s;' /path/to/file
Add a g after the /s if you want to handle multiple matches. Add more
s/.../.../gs; constructs if you want to handle multiple patterns.
Should be possible in both sed and awk too, but I'm too lazy to read the
manuals right now.
