    This may sound too silly !!

    I have the following as part of a cold backup script
    ....
    cp /u01/app/oracle/oradata/db1/system01.dbf
    compress -f /data3/DB1/backup/system01.dbf
    .... etc.

    I came across another script for cold backup that goes as follows
    ....
    !cp /u01/app/oracle/oradata/db1/system01.dbf
    !compress -f /data3/DB1/backup/system01.dbf
    .... etc.

    My question is, what does "!" mean/stand for ? Which is the right script ?

    Thank you guys!
