i am using a sed utility to replace some characters in my shell scripts. it works gr88 for all most all recds in the flat file, but except for one recd it says memory core dump. becoz that line huge.. so when i break that line into 2. sed works gr8 again. how should i solve without breaking that recd in 2 lines. anyone can answer this? please need help.

kapil,
The simplest answer is to use Perl. It does not come
up against lots of the UNix restrictions for
sed/awk/shell commands.
Alternatively, continue as you have done and break it
into 2, then reunite.
Or you might try the dd command.
dd | if=your input file | sed .... > outputfile
This might work as dd uses individual bytes, but that
would restrict your options for what you can change.

Peter,
Thanks a lot man, I know even "tr" works gr8, but i can replace only one char at a time. is it possible to replace a char with a string using "tr" or "dd". Thanks again.
