Hi to all



i make a script to automate burning backup files on dvd
it works fine if i start it from root user, but if i start it
from cronjob do noting...
i try on growisofs the option -use-the-force-luke=force but nothing happens

i check the env of cron

totdimfile=0
for FILE in $(/bin/ls -r $bkup_path$prefix)

do
dimfile=`/bin/ls -l $FILE | /usr/bin/awk -F " " '{print $5}' `
let "totdimfile += dimfile";

if [ "$totdimfile" -lt "4700000000" ]
then
NAMEFILE=`/bin/ls -l $FILE | /usr/bin/awk -F " " '{print $8}' `
ALLNAMEFILE="$ALLNAMEFILE $NAMEFILE";
fi
done
/usr/bin/growisofs -use-the-force-luke=force -Z /dev/scd0 -R -J $ALLNAMEFILE

Solved!!!

for anyone has this problem….
i fix the script and now works fine!!

i fix the row with growisofs as described in this post

http://lists.debian.org/cdwrite/2003/10/msg00023.html

and i realize that i've got another problem, i use ls and awk in my script
to retrieve the name of file and the size of file.


this is the output of ls launched of cronjob

root@db:/# cat /tmp/dd.txt
-rw-r--r-- 1 nicola root 848860160 Aug 3 06:11 /bkrepo/PAR_20100802LUN.gz

see the date i … 2 fields,

this is the output of ls launched from interactive shell


root@db:/# ls -l /bkrepo/PAR_20100802LUN.gz
-rw-r--r-- 1 nicola root 848860160 2010-08-03 06:11 /bkrepo/PAR_20100802LUN.gz

here the date only one field,


with awk from cronjob i must retrieve the name of the file with {print $9} instead of {print $8}

i bet the locale from cronjob is different than the interactive shell….i must investigate
