I want to add
0 5 1 * * goaccess -f /var/log/nginx/access.log -a > /home/xan/reports/report-week-$(date +%Y.%m.%d).html
but crontab always complains about that:

What the proper syntax to do that?
% has special meaning in a crontab (it represents a newline), so you need to escape it to specify a literal percent sign.
0 5 1 * * goaccess ... > /home/xan/reports/report-week-$(date +\%Y.\%m.\%d).html

I got the following error from executing a line in my Vixie Cron file:
/bin/sh: 1: cd: can't cd to $HOME/prg/gridtrader
Which to me means that $HOME is not being expanded even though crontab(5) says it will be and the log from execution shows HOME as being defined.
The cron file looks like so:
GT_DIR = $HOME/prg/gridtrader
PYTHON_EXE = $HOME/install/python37/bin/python3
APPLICATION = gridtrader/gridtrader.py
ACCOUNT = metaperl_yobit
# GRID TRADER
*/5 * * * * cd $GT_DIR && $PYTHON_EXE $APPLICATION --monitor $ACCOUNT
The log message I got is:

As you can see the, from the shell, there is no problem executing this cd command:

LICENSE SPEC.md accounts doc log requirements.txt system.ini tmp venv
README.md StatusReport.docx batch gridtrader persistence src system.ini.sample tradelog.docx
schemelab#metta:~$ cd /home/schemelab/prg/gridtrader

You have run into one of cron's most common problems, trying to use it like an arbitrary shell script. Cron is not a shell script and you can't do everything you can do in one, like dereferencing variables or setting arbitrary new variables.
I suggest you replace your values into the cron line and avoid usage of variables:
# GRID TRADER
*/5 * * * * cd $HOME/prg/gridtrader && $HOME/install/python37/bin/python3 gridtrader/gridtrader.py --monitor metaperl_yobit
Another approach to the problem of unexpanded cron variable content is eval:
*/5 * * * * eval cd $GT_DIR && eval $PYTHON_EXE $APPLICATION --monitor $ACCOUNT

I am running this command on cron:
0 4 1 * * myfunc `date +%Y-%m`; anotherfunc
on my mail file /var/spool/mail/myuser, I get this message:

/bin/sh: -c: line 0: unexpected EOF while looking for matching ``'
/bin/sh: -c: line 1: syntax error: unexpected end of file
what am I doing wrong?
I found the reason: it's because % should be escaped with \
the correct version would be:
0 4 1 * * myfunc `date +\%Y-\%m`; anotherfunc

I am running a weather forecast model and I want to automate the modek runs via crontab. When I submit my job interactive through:
qsub -I -l nodes=8:ppn=8 -l walltime=2:00:00
The job runs ok.
When I submit through crontab, the job disappears without any trace, no error file any where, no output file, except mail which reads as:
From: root#master.cluster (Cron Daemon)

Here is my crontab entry
50 09 * * * PATH=/opt/torque/bin:/usr/bin:/bin:. qsub /home/test/WRF/SCRIPTS/wrf_submit_00.sh
and wrf_submit_00.sh has two dependent jobs to run consecutively
#!/bin/bash
cd WRF/WRFV3/run
FIRST =`qsub wrf_initialise.sh`
echo $FIRST
SECOND = `qsub -w depend=afterok:$FIRST wrf_00_run.sh`
echo $SECOND
exit 0
and the first job is
#!/bin/bash
#PBS -l nodes=8:ppn=8
cd WRF/WRFV3/run
echo -n "this script is running on: "
hostname -f
date
echo ""
echo "### PBS_NODEFILE (${PBS_NODEFILE}) ###"
cat ${PBS_NODEFILE}
echo ""
mpirun ./real.exe
exit 0
When I submit the two jobs separately through crontab I get the same disappearance.
Please help!, am stuck. Google search of a similar problem gives me no clue.
Herer is my CRONTAB file (Ubuntu 10.10):
57 1 * * 2-6 ET=`date --date 'yesterday'+%Y%m%d`;echo $ET
Even The syntax color indicate that something is wrong. and there is this error:
Subject: Cron <root> ET=`date --date 'yesterday' + (failed)
Content-Type: text/plain; charset=ANSI_X3.4-1968
X-Cron-Env: <SHELL=/bin/sh>
X-Cron-Env: <HOME=/root>
X-Cron-Env: <PATH=/usr/bin:/bin>
X-Cron-Env: <LOGNAME=root>
/bin/sh: Syntax error: EOF in backquote substitution
But I am not sure whats wrong. Thanks a lot!
Cron needs to escape the % sign - http://www.hcidata.info/crontab.htm
Try it with a backslash:
57 1 * * 2-6 ET=`date --date 'yesterday' +\%Y\%m\%d`;echo $ET
