Linux CP command

[keith smith]

No you all did a great job!!  Thank all of you for your suggestions!  I just need to play with cp some more.  It does not work the way I expect.  Probably those 10 years I spent on the DOS command line - my formative years :)

Glad you got it.
sudo cp -r for directory is required; and paths can be difficult.
Sheesh, you asked us clearly, but it took 10 volleys to get you an answer.We will have to try harder.

I think I tried that also.  I ended up doing a dump and an import.

Thank you all for your help and insight!

Mysql stores the databases in an individual folder for each database. You need to use -r (recursive) option with the cp to make it work properly.


Eric had the right syntext in his posting, but the trailing /. isnt' needed.



sudo cp -r DB1 DB2

sudo cp DB1/* DB2/ should have worked.  The fact that it's giving you a file not found is a little confusing.  My guess is that you have either have a typo in the source database folder name, or more likely you haven't taken into account that Linux file systems are case sensitive.

Hi,



For some reason I just don't get the cp command. Maybe it is the deep

rooted MS DOS from the 80's and 90's. I spent about a decade using MS DOS.



Here is what is going on. I am in a CentOS box and do not ever become

root. I use sudo.



I want to copy one MySql DB to another so I can use the data for testing.



1) I cd to /var/lib/mysql

2) I can see both DB's

3) I issue any number of commands that do not work.



Lets say DB1 is the source directory & DB2 is the destination directory



mysql]$ sudo cp DB1/*.* DB2/ Results: cp: cannot stat `DB1/*.*': No such

file or directory



mysql]$ sudo cp DB1/* DB2/ Results: cp: cannot stat `DB1/*': No such

file or directory



mysql]$ sudo cp DB1/ DB2/ Results: creates the directory DB1 under DB2

and copies all the files into DB2/DB1



mysql]$ sudo cp DB1 DB2/ Results: does not seem to do anything.



http://www.computerhope.com/unix/ucp.htm shows this example: cp -r

/home/hope/files/* /home/hope/backup



mysql]$ sudo cp -r /var/lib/mysql/DB1/* /var/lib/mysql/DB2 - cp: cannot

stat `/var/lib/mysql/baseline/*': No such file or directory



This is driving me crazy. Any help much appreciated!
