```
mvtspro-main:/cdrs/backup# cat /usr/local/ky4k0b/cdrs_backup_daily.sh
#!/bin/sh
mask=`date --date="yesterday" +%Y%m%d\*`
arch_name=`date --date="yesterday" +%Y%m%d`
find /cdrs -type f -name "$mask"|zip -m /cdrs/backup/$arch_name.zip -@

```

where did I make a mistake? Thanks!
PS: If I run this script manually it works fine.
