Samba share permissions.
Copying files from a Samba share to Mac OS.
Mount the Samba Share with Correct Options: Ensure the Samba share is mounted with appropriate options that allow the necessary permissions. You might need to specify certain options when mounting the share to ensure full access.
By following these steps, you should be able to resolve possible error issues and successfully copy your files.
The "Permission denied" error typically occurs due to a lack of sufficient privileges to change the permissions on the specified files or directories. This can be due to several reasons, such as the current user not owning the files or lacking the necessary permissions to modify them.
To address this issue, you can try the following:
Ensure that you are the owner of the files and directories you are trying to change. You can check the ownership using the ls -l command.
Check File Ownership: ls -l /path/to/directory
If you have administrative privileges, you can use sudo to execute the chmod command with elevated permissions. This allows you to modify files and directories even if you are not the owner.
Use sudo: sudo chmod -R 777 /path/to/directory
Make sure no files in the directory are locked.
Check for File Locks: sudo chflags -R nouchg /path/to/directory
Sometimes, the error is caused by hidden files (like .DS_Store). The dot_clean command can merge these hidden files with their parent directories.
Sometimes hidden files (such as .DS_Store or temporary files) can be in use. Use the following command to list all files, including hidden ones:
Check for Hidden Files: ls -la /path/to/directory
Use the dot_clean Command: dot_clean /path/to/directory
Remove Extended Attributes: Use the xattr command to remove extended attributes:
sudo find /mnt/mountpoint -exec xattr -c {} + 2>/dev/null
To remove extended attributes recursively, you can use the xattr command with the -r option. The -r option stands for "recursive" and will apply the command to the specified directory and all its subdirectories and files.
Here's how you can do it:
sudo xattr -rc /mnt/mountpoint
This command will recursively remove all extended attributes from the Milwaukee directory and its contents. The -c option clears (removes) the extended attributes, and the -r option ensures this is done recursively.
Copy Files: Use the cp command to copy files from the Samba share to the mounted drive. The -R option allows you to copy directories recursively.
cp -R /Volumes/SambaShare/myfiles /Volumes/DestinationDrive/mybackup
Additional Options If you want to see the progress of the copy operation, you can use rsync instead of cp:
rsync -av --progress /Volumes/SambaShare/myfiles /Volumes/DestinationDrive/mybackup
Copy Files with rsync:
Use the rsync command with the --ignore-errors option to skip files that cause errors.
rsync -av --ignore-errors /Volumes/SambaShare/myfiles /Volumes/DestinationDrive/mybackup
Example Command Breakdown -a: Archive mode, which preserves permissions, timestamps, symbolic links, etc. -v: Verbose, so you can see the progress. --ignore-errors: Continue copying even if there are read errors.
Partial Transfers: If you want to keep partially transferred files, you can add the --partial option:
sudo rsync -av --ignore-errors --partial /Volumes/SambaShare/myfiles /Volumes/DestinationDrive/mybackup
Exclude the directories causing permission issues if they are not necessary for the copy process.
Run rsync with --exclude: sudo rsync -av --ignore-errors --exclude=".TemporaryItems" --exclude="Directory_Name" /Volumes/SambaShare/myfiles /Volumes/DestinationDrive/mybackup
If .TemporaryItems is causing the issue and is not critical, you can try removing it directly. Be cautious, as deleting system or temporary files can sometimes have unintended consequences.
Remove .TemporaryItems: sudo rm -rf /Volumes/SambaShare/myfiles.TemporaryItems
Deleting Source Files after Copy: If you want to delete the source files after successful copying, use the --remove-source-files option:
sudo rsync -av --ignore-errors --remove-source-files /Volumes/SambaShare/myfiles /Volumes/DestinationDrive/mybackup
By using rsync with these options, you can effectively copy files from a Samba share to a mounted drive on macOS, skipping any files that cause errors during the transfer.
In Unix-like operating systems, file permissions are represented using a combination of letters and symbols. The string -rwxrw-rw-@ can be broken down as follows:
Check Permissions of files in directory: ls -l /path/to/directory
File Type:
The first character (-) indicates the type of the file. In this case, it is a regular file. Other possible characters include d for directories, l for symbolic links, and so on. Owner Permissions:
The next three characters (rwx) indicate the permissions for the owner of the file. r means the owner has read permission. w means the owner has write permission. x means the owner has execute permission. Group Permissions:
The following three characters (rw-) indicate the permissions for the group that the file belongs to. r means the group has read permission. w means the group has write permission.
The next three characters (rw-) indicate the permissions for others (everyone else). r means others have read permission. w means others have write permission.
The final character (@) indicates that the file has extended attributes. These attributes provide additional metadata about the file. You can view these extended attributes using the xattr command on macOS or certain Linux systems (e.g., xattr -l filename). In summary, -rwxrw-rw-@ means:
It is a regular file. The owner has read, write, and execute permissions. The group has read and write permissions, but no execute permissions. Others have read and write permissions, but no execute permissions. The file has extended attributes.
