The chmod command is used to set the permissions to grant or restrict access to your
directories/files.
- all directories, starting at your home directory down to the directory where the files are located should be set to world readable and world executable Permissions can be set on a group of files, by using wildcards("*" and/or "?") for files that have a common pattern in the filename, or set permissions recursively for all directories/files under and including a parent directory, by using the "-R" option. To unset the world permissions that were set with the commands listed above use o-. See the man pages for the chmod command for more info. Note: Default permission on user's home directories are world executable, which allows a pass through behavior. These permissions will restrict anyone from listing the contents of the owner's home directory, but will allow a requester to list a specific target file or sub-directory's contents provided, the owner gives the requester the exact path to the target file or directory and that the permission have been set on the targets to enable access for the user who has requested access to the targets. For additional info on setting permissions on directories/files you can find several online tutorials like Wikipedia - chmod Linux Ownership and Permissions Lab Tutorial for chmod Modify User Permissions What is NCSA's refund policy for lost jobs?NCSA's refund policy is described in the HPC Account Management web page.
