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.

Hi all
I've run into a snag in a program of mine where part of what I entered in at the start of run-time, instead of the current value within printf() is being printed out.
After failing with fflush() and setbuf(), I tried the following approach
void BufferFlusher()

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.

log::log4perl::appender::screen
Appender::Screen(3) User Contributed Perl Documentation Appender::Screen(3)NAME
Log::Log4perl::Appender::Screen - Log to STDOUT/STDERR
SYNOPSIS
use Log::Log4perl::Appender::Screen;
my $app = Log::Log4perl::Appender::Screen->new(
stderr => 0,
utf8 => 1,
);
$file->log(message => "Log me
");
DESCRIPTION
This is a simple appender for writing to STDOUT or STDERR.
The constructor "new()" take an optional parameter "stderr", if set to a true value, the appender will log to STDERR. The default setting
for "stderr" is 1, so messages will be logged to STDERR by default.
If "stderr" is set to a false value, it will log to STDOUT (or, more accurately, whichever file handle is selected via "select()", STDOUT
by default).
Design and implementation of this module has been greatly inspired by Dave Rolsky's "Log::Dispatch" appender framework.
To enable printing wide utf8 characters, set the utf8 option to a true value:
my $app = Log::Log4perl::Appender::Screen->new(
stderr => 1,
utf8 => 1,
);
This will issue the necessary binmode command to the selected output channel (stderr/stdout).
