This bit is wrong:
Should be
If you want to write to two log files, you should combine this with tee:
I just ran this on ksh and bash on AIX, Linux and Solaris, and sh on Solaris, and it works the same on all of them - but only when feeding log through a pipe - not calling it directly. What OS/Shell are you using?
Maybe it would be best if you showed your script - exactly what you are doing - including where you set variables, like LOGFILE, LOG_FILE_1, LOGFILE_2, PROGRAM, etc...
Are you sure following helped you to capture stderr into output.log log file?
It appears you are directing stdout to output.log in a non-appending mode.
Did you try this ?
Your code -->
The closest solution I have tryed is the following:
I obtain the stdout inside $LOGFILE_1 and the stderr inside $LOGFILE_2 BUT without the date before it, as I wanted to.
Simply the log function is not called at all.
Variables $LOGFILE_1 and $LOGFILE_2 are something like
, so nothing special.
$command is an executable written in C a bit hard to explain what it does...but it prints strings either on stdout and stderr, I think it is enough to describe my problem.
I tryed also with
but I obtain the stdout (with date) in the log file and
(notice the "2>>" inside the function), but I obtain the stderr inside the log, WITHOUT the date.
I think that the problem can be summarized into this question: how to pass the stderr to a function?
There is no point in directing output of standard error in your log function using 2>> because there never is any.
Standard error is directed to where standard output is going at this point in time (i.e. the screen, standard output)
Standard output is then sent to LOGFILE_2
Standard error (still pointing to where standard output was pointing before it was changed) (i.e. the screen) is piped into the log function
The log function should write standard output - not standard error - to LOGFILE
All you are doing here is writing standard output to LOGFILE_1 and standard error to LOGFILE_2. There is nothing left for the log function to do - you left nothing to be piped into it.
Here, you have sent standard error to LOGFILE_2 (you're missing a quote on that line), standard output goes to the log function, which you also write to LOGFILE_2
And here, you have written standard error to LOGFILE_2, standard output goes to the log function, but you do nothing with it, as you're directing standard error to LOGFILE_2 (although there is nothing in standard error to write to the file)

Hello,
Can you please if the bellow is the proper way of appending a variable to the stderr:
The easiest way to test this,I was able to imagine, was by touching 5 files and afterwards looping trough to the results:
-rw-r--r-- 1 ab owner 0 Sep 14 13:45 file1
-rw-r--r-- 1 ab owner 0 Sep... (7 Replies)

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

Hi,
Need some help here on a script I'm writing. I know that STDERR is normally done is this manner:
