Bash multiple output redirection
Hello all. Is there a way to redirect output to more than one file at a time?

I have a method1() that writes to a logfile. In the method cksums are done on files by doing a
"for i in `ls`; do
cksum $i > $LOGFILE
done
"
In the logfile I want to show the cksums under each directory like ths:

Logfile:
##########
cksum on dir 1
##########
12323239 file1

##########
cksum on dir 2
##########
12323239 file1

At the same time I would like to keep a list of all the cksum in another file like this:

CKSUMLOG:
12323239 file1
12323239 file1

I dont want to cat or create a lot of temporary files. Is there a way to do this with some I/O commands?

Thank you for your time.

LEARN ABOUT SUSE

lzcmp

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp or diff.  If only one file is specified, then the files compared are file1 (which must have a suffix of	a  supported  com-
       pression  format)  and  file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp or diff is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
