Hi,

I posted something here about this yesterday but I can't seem to
find it. I needed help writting a script which would append a file
with new lines after every so many charachters.

Example: (my original flat file)

L60 LETTER OF CREDIT 60 DAYS W00 ON RECEIPT WIRE TRANSFER W30 NET 30 WIRE TR
ANSFER W45 NET 45 WIRE TRANSFER W60 NET 60 WIRE TRANSFER

I need to look like this:

L60 LETTER OF CREDIT 60 DAYS
W00 ON RECEIPT WIRE TRANSFER
W30 NET 30 WIRE TRANSFER
W45 NET 45 WIRE TRANSFER
W60 NET 60 WIRE TRANSFER

Basically, I needed a script that inserted a new line after so many chars.

This is the script someone helped me out with:

====
#!/usr/bin/nawk -f
#
###fold.awk
#

{
if (!width) width=31;
line = $0;
do {
newline = substr(line, 0, width);
if (newline !~ "^[ \t]*$") { print newline }
line = substr(line, width+1);
}
while (length(line) > 1);
}
====

This works great! However, now I'm having a problem with "line too long"
errors with extremely large files:

nawk: input record `0101100010HORSES AND...' too long
source line 16 of file /usr/local/bin/fold.awk

I know there is a limit in awk. Also, from the post from yesterday, someone
was really pushing an SED script. Can SED handle large lines?

Does someone know if I can do this another way or with the same
script? This is a hot one for me.

Thank you for this great board!

Thanks!
