Copy control file

Question

I found my control parameter file in my $ORACLE_HOME/dbs/initarcedev.ora
The parameter file is under the path /opt/app/oracle/data3/oradata/arcdev/control101.ctl, /opt/app/oracle/data3/oradata/arcdev/contro102.ctl, /opt/app/oracle/data3/oradata/arcdev/control103.ctl
I cannot navigate to arcdev since it does not exist so do I need to create the directory and copy the above ctl files to the directory and then from sqlplus type startup?
Can somebody send me the copy command in Linux?
BTW I have a spfilearcdev,or and spfilearcdevora.bak already in place.

Thats exactly my problem I cannnot start the instance. I get the ora-00205 error. I know it has something to do with control file. I thought I might copy the ctl file to a new directory under /opt/apps.../data3/ and call it arcdev since it does not exist and then do a startup. Am I going the right direction or am I missing something?

ORA-00205 can be caused for at least two reasons:
1) Your controlfiles are not where they are supposed to be according to the CONTROL_FILES parameter inside spfile resp. init.ora
2) One or more controlfiles are damaged resp. of different ages
My recommendation is: Make safety copies of all your 3 controlfiles. Then copy the controlfiles one after another to a location of your choice and set the CONTROL_FILES parameter to that controlfile. Try to startup. One of the 3 startups should at least succeed. Copy that controlfile to two other locations of your choice (with instance shut down) and change the CONTROL_FILES parameter accordingly. If no controlfile is usable for startup, restore one from backup or create a new one with the CREATE CONTROLFILE statement.
