Re: Shell script in crontab cannot write files into FreeBSD's filesystem. (2nd evised version)



Hi list,

Thanks, Derek. You're right. The date command must be the absulute path. Now it works.


Thanks for your best answer.

Hi all,

Please anybody help me, I faced the problem with my "crontab".
I tried to run a shell script which will fetch webpage and save it to
a directory by using wget but after few minute I cannot see any file
in such directory

Below are content of shell script, my crontab and also
file's permission listing.

##########################
# Output of `crontab -l`
##########################
SHELL=/bin/sh
MAILTO=pjn
* * * * * . /home/pjn/parseGP/fetchPage.sh


########################
# file: fetchPage.sh
########################
#!/bin/sh
TIMESTAMP=`date "+%Y%m%d-%H%M%S"`

You are assuming that date is in your path by the above statement. Never
assume you have a good path, unless you set it in your script file. So,
either setup the path you need or use absolute pathnames such as:
TIMESTAMP=`/bin/date "+%Y%m%d-%H%M%S"`


LOGPATH="/home/pjn/parseGP/logs"
/usr/local/bin/wget --no-cache -a ${LOGPATH}/fetch.log -O
${LOGPATH}/${TIMESTAMP}.html http://www.blahblah.com


########################
# Files' permission
########################
blahHost$
blahHost$ls -ltrd parseGP
drwxr-xr-x 3 pjn pjn 512 Dec 5 14:27 parseGP
blahHost$ls -ltr parseGP/
total 4
drwxr-xr-x 2 pjn pjn 512 Dec 5 15:11 logs
-rwxr--r-- 1 pjn pjn 226 Dec 5 15:21 fetchPage.sh
blahHost$ls -ltr parseGP/logs/
total 0
-rw-r--r-- 1 pjn pjn 0 Dec 5 15:14 fetch.log
blahHost$



TIA
Pote

Make sure your script runs correctly outside cron, then test it from inside
cron. Add some echo statements so you can see what is executed, such as:
#!/bin/sh
TIMESTAMP=`/bin/date "+%Y%m%d-%H%M%S"`
LOGPATH="/home/pjn/parseGP/logs"
echo $(TIMESTAMP)
echo $(LOGPATH)
echo /usr/local/bin/wget --no-cache -a ${LOGPATH}/fetch.log -O
/usr/local/bin/wget --no-cache -a ${LOGPATH}/fetch.log -O
echo ${LOGPATH}/${TIMESTAMP}.html http://www.blahblah.com
${LOGPATH}/${TIMESTAMP}.html http://www.blahblah.com
