Can somebody explain to me why the diff output is not going to stderr?
Yet when I issue a diff from the command line the return code is -ne 1.
I am guessing diff always writes to stdout???
Is there away I can force the difff to write to stderr USING THE CURRENT
template. If possible, I would like to uncomment the first diff and get
that to write to stderr. Any examples would be greatly appreciated.
This needs to work with ksh.....
How can I redirect and append stdout and stderr to a file when using cron? Here is my crontab file:
*/5 * * * * /dir/php /dir/process_fns.php >>& /dir/dump.txt
Cron gives me an 'unexpected character found in line' when trying to add my crontab file.
Regards,
Zach Curtis

In bash, I need to send the STDOUT and STDERR from a command to one file, and then just STDERR to another file. Doing one or the other using redirects is easy, but trying to do both at once is a bit tricky. Anyone have any ideas? (9 Replies)

I have been doing this:
make xyz &> xyz.log &; tail -f xyz.log
The problem with this is that you never can ge sure when "make xyz" is done.
How can I pipe both stderr and stdout into tee so both stderr and stdout are copied both to the display and to the log file?
Thanks,

working on a c sell script
I think I understand the concept of it, which is:
filename >> file.txt (to appaend)
or filename | tee -a file.txt (to append)
The problem is that my shell script is used with several parameters, and these commands don't seem to work with just filename. They... (2 Replies)

zdiff
ZDIFF(1) BSD General Commands Manual ZDIFF(1)NAME
zcmp, zdiff -- compare compressed files
SYNOPSIS
zcmp [options] file [file2]
zdiff [options] file [file2]
DESCRIPTION
zcmp and zdiff are filters that invoke cmp(1) or diff(1) respectively to compare compressed files. Any options that are specified are passed
to cmp(1) or diff(1).
If only file1 is specified, it is compared against a file with the same name, but with the extension removed. When both file1 or file2 are
specified, either file may be compressed.
Extensions handled by gzip(1):
o z, Z,
o gz,
o taz,
o tgz.
Extensions handled by bzip2(1):
o bz,
o bz2,
o tbz,
o tbz2.
Extensions handled by xz(1):
o lzma,
o xz,
o tlz,
o txz.
ENVIRONMENT
TMPDIR Directory in which to place temporary files. If unset, /tmp is used.
FILES
/tmp/zcmp.XXXXXXXXXX Temporary file for zcmp.
/tmp/zdiff.XXXXXXXXXX Temporary file for zdiff.
SEE ALSO bzip2(1), cmp(1), diff(1), gzip(1), xz(1)CAVEATS
zcmp and zdiff rely solely on the file extension to determine what is, or is not, a compressed file. Consequently, the following are not
supported as arguments:
- directories
- device special files
- filenames indicating the standard input (``-'')
