Home: Perl Programming Help: Intermediate: file creation

1951g New User Jun 16, 2008, 3:27 PM Post #1 of 6 (1990 views) file creation Can't Post I want to write a perlscript that will traverse through a series of subdirectories and print out a dynamic string to a new file that will be executed separately from perlscript that created it. The perlscript would take 2 arguments: directory name and destination server. So if I passed the following 2 arguments to the perlscript: /opt/oracle/oradata destServerXYZ It would generate the following in a file that I would execute later. cp /opt/oracle/oradata01/redo1.dbf cp /opt/oracle/oradata01/control1.dbf cp /opt/oracle/oradata02/redo1.dbf cp /opt/oracle/oradata03/subdir/usertablespace.dbf Is there a good way to do this with a perlscript so no matter what server I'm on or directory structure I give, it'll start at the top level of the directory I give and traverse through subdirectories and files to construct the cp statements? Thanks for any help with this.

How is destServerXYZ part of what you want to do? Also, you might be able to do this with just the Unix find utility: find /opt/oracle/oradata -name '*.dbf' -exec echo cp '{}' ... ';'

Actually, I'm going to be using rsync instead of cp since I'm going from 1 server to another keeping same directory structure but wanted to be able to use this perlscript as a utility to run on any server giving it the 2 arguments to construct the directories. rsync /opt/oracle/oradata01/redo1.dbf destinationserver:/opt/oracle/oradata01/redo1.dbf rsync /opt/oracle/oradata01/control1.dbf destinationserver:/opt/oracle/oradata01/control1.dbf rsync /opt/oracle/oradata02/redo1.dbf destinationserver:/opt/oracle/oradata02/redo1.dbf rsync /opt/oracle/oradata03/subdir/usertablespace.dbf destinationserver:/opt/oracle/oradata03/subdir/usertablespace.dbf Thanks.

meloyelo User Jun 17, 2008, 8:04 AM Post #6 of 6 (1966 views) Re: [1951g] file creation [In reply to] Can't Post You may not have to write any perl at all -- rsync has the capability to perform recursive copies and also to match file names (see the --include and --exclude options.)
