Data sharing

Unix file permissions

Unix permissions


NERSC provides two commands: give and take which are useful for sharing data between users.

To send a file or path to <receiving_username>:

nersc$ give -u <receiving_username> <file or directory>

To receive a file sent by <sending_username>:

nersc$ take -u <sending_username> <filename>

To take all files from <sending_username>:

nersc$ take -a -u <sending_username>

To see what files <sending_username> has sent to you:

nersc$ take -u <sending_username>

Files that remain untaken 12 weeks after being given will be purged from the staging area.

For a full list of options pass the --help flag.

project directories

The project filesystem allows sharing of data within a project.
