7 File Systems
Each user has access to two basic directories: home and scratch.
When you first log in, your current working directory is ‘/home/<username>’, where <username> is
your Pete username.
– ‘/home/<username>’ has a quota of 1GB by default. Your source code and executables should
be stored here.
This filesystem is NOT BACKED UP, but it does have snapshots. To check your current
usage, type ‘du –sh’ from your home directory.
– ‘/scratch/<username>’ is for temporary storage of large files and large collections of files. This
filesystem is NOT BACKED UP.
NOTE: The first / in a file system path represents the ‘root’ – or the first or top-most directory in your
file system. When you log into Pete, you are automatically in your home folder which stems from the root.
Your current working directory would look like ‘/home/<username>’, with the first / representing the root.
All proceeding / in a file path serve as dividers between any subsequent directories and files.
