rcp missing hidden files.

Russ Hancock_1 — Fri, 17 Jan 2003 09:54:02 GMT

I'm issuing a rcp command to copy files/directories between machines. The problem is the resulting directory is missing any hidden files/directories.

Is there a flag I can set to make sure the hidden files go across.

I'm using rcp -rp hosts:/file /file2

Hi,

I'd never heared about such a problem. Please check with 'ncheck' if there are realy hidden files.

Regards ...

Hello Russ,

Can't find an option for rcp to include hidden file, but you can use find in combination with cpio.

# cd /home/user
# find . | cpio -ov | remsh server " cd /home/user ; cpio -idvum "

Hi,

I'm not aware of any flags fro rcp for hidden files. I've just used rcp to copy a users home directory & all of the hidden files have come across OK.

Regards,

Hilary

Hi-

When rcp -r is copying a directory (rcp -rp host:/remotedir /localdir), it should always include all files it can read, hidden or otherwise. If it doesn't then it's broken.

When you use "rcp -rp hosts:/file /file2" (explicitly naming the files), rcp will copy those filenames it is given by the shell (after wildcard expansion). If that includes hidden files, they should be copied.

Is there a chance you're doing something like "rcp -rp hosts:/* /localdir"? That would ignore hidden files because the * wildcard won't match them.

rcp handles hidden files just fine. The problem is that you are not specifying them in the command line. A hidden file (files that start with .) are 'hidden' from standard filename generation by the shell. If you type echo *, you won't see any . files, so rcp * produces the same result. Like ls, rcp and echo don't know anything about filename expansion--the * is just a character. Turn off the shell's special handling with the \ character and type the echo command as in: echo \* and you'll see just * not filenames.

So to get hidden files, DO NOT TYPE rcp .*!!!!! To see what you will get, always use echo first as in echo .* ...if you are in a subdirectory, you will be very surprised to see directories and files one level up in the listing! That's because .* matches the hidden directory called: .. which is a real directory, and not what you want.

The easiest solution is to use rcp's ability to copy an entire directory with -r as in:

rcp -r /some_directory_path ...

or if you need just the files in a specific directory, use a regular expression that finds the hidden files but not the .. directory as in:

echo * .[!.]*

and

rcp * .[!.]*

The regular expression .[!']* says: match all normal files and directories (*) and then match all files that start with . but not files that have a . in the second character. This will miss files that start with .. but they can be handled with .??* which matches all files starting with . followed by any 2 characters or more.

If you are copying an entire directory rcp -r should work. As Bill pointed out, if you are copying files instead of directories, rcp * will not pick up dot files. I use .??* whenever I want to include dot files. This will include any dot file that is 3 characters or more (not . or ..). Be careful there can also be dot directories which could choke if you are not using the -r option.

Good Luck.
