You can try "sed" (originally under Unix, now ported to most OSes).
I would recommend GNU sed 3.02 which comes on every relatively
recent version of Linux (SuSE, RedHat etc).
Number of records is irrelevant and the GNU version also has no
record (line) length restriction
Have a look at the excellent FAQ at http://www.ptug.org/sed/sedfaq.htm
Good luck,
Michael.
