Hello,
I'm in the situation where I have to port large binary files to my system at
home by physically carrying the stuff home on floppy disk via MSDOS. Since
these files are often quite large (5-8 Mbyte), I run uuencode on the binary
file and then cut the resulting text file into chunks that will fit onto a
floppy disk.
Does anyone have a program that will do this function, so that I could, for
example, enter:
uuencode binary_filename | <program> text_filename
and program will create as many text files with the root name of text_filename
as are required? I thought I'd ask first before writing such a program myself!
Thanks,
- Paul jpm@logixwi.uucp (Jan-Piet Mens) (06/06/91)

I thought I'd ask first before writing such a program myself! How about: $ uuencode binary_file | split this will create as many files as necessary. These are called `x??'. At home, you get them together again with: $ cat x?? | uudecode >Thanks, Pleasure. -- Jan-Piet Mens, Logix GmbH jpm@logixwi.UUCP Moritzstr. 50, D-6200 Wiesbaden ...!uunet!mcsun!unido!logixwi!jpm

I thought I'd ask first before writing such a program myself! Csplit is probably a good way to go, but here's another, which may chop off a line before the nl, though. : chunk - breakup a file into SIZE chunks called OUT01, OUT02, ... [ !-r "$1" ] && echo "Usage: $0 inputfile [prefix [size]]" IN=$1 OUT=${2:-chunk} SIZE=${3:-100000} N=0 while : do T=`expr $N + 1` [ $T -le 9 ] && T=0$T dd count=1 bs=$SIZE if=$IN skip=$N of=$OUT$T [ ! -s $OUT$T ] && rm $OUT$T && break N=`expr $N + 1` done l $OUT* $IN Jean-Pierre Radley Unix in NYC jpr@jpr.com jpradley!jpr CIS: 72160,1341
