Hello frends! i am using postgresql database. I am using crond for daily backup. Following is the crontab entry, 29 17 * * 1-6 postgres /path/to/script.sh 'script.sh' contains PGUSER=postgres pg_dumpall > /path/to/backup_date.sql Running the script using crond creates the 0 byte files. But , If i run the script in console , it creates the file with content. Any suggestion pls? Regards Bala
