![]() Rm file Removes 'file' provided you have write permission on it. See the UNIX manual pages for the above programs by using the ' man', for example ' man gzip'. Prints the compressed file(s) to the terminal\ Zip file.zip file1 Compresses one or more files to file.zip ![]() Tar czf file1 Compresses one or more files into Tar xzf Uncompresses to the contents of file.tar Gunzip file.gz Uncompresses file.gz to file Infrequently accessed files may be compressed to save disk space. Send email to to request space under /scratch. Files that are not actively being used should be compressed if possible. If space becomes limited we may automatically compress files or (if time permitting) ask users to either remove or archive files that are no longer needed in order to make room for other users. Unlike users' home directories, they are not backed up, but can usually accommodate larger data files. ![]() scratchĭirectories under /scratch exist on the file server and can be accessed from every machine. This directory functions similarly to /var/tmp, however, it does not get erased when the computer is reinstalled or reconfigured. The /var/tmp/scratch directory exists on some workstations that have secondary disks. The /Users/Shared directory functions identically to /var/tmp, except it is only found on our Macintosh computers. Otherwise, the same policies that apply to /tmp apply to /var/tmp. This directory does get erased, however, whenever the workstation needs to be reinstalled or reconfigured. The /var/tmp directory functions similarly to /tmp, however, files are not automatically removed after the machine is rebooted. Remove files when they are no longer needed. Do not use /tmp if less than 30% of the space is available. To find out how much space is available in /tmp on your system, type ' df -k /tmp'. However, if /tmp is full, editors, compilers, and many other programs will not work or behave erratically. The limit to the amount of storage a user can take up is the physical limitation of the partition. To reference your files using /tmp, use ' /tmp' as the prefix to the name of the file, for example ' /tmp/myfile'. No special permissions are required to use /tmp. Do not use /tmp for data that that is difficult or expensive to re-create. Remember that there is no guarantee that files stored in /tmp are safe. However, if you need a large amount of disk space for a short amount of time, /tmp provides a solution which does not need any staff intervention. Files may also be deleted with little or no warning if resources become scarce. tmpįiles put in the /tmp directory are only accessible on the machine on which they were created and are automatically wiped everytime the computer is rebooted. These areas are often larger than home directories, but they are not backed up and may be removed without notice. There are several places where users can temporarily store data. Reports your disk quota and current disk use. ![]() Most information: lists size of all files in all directories and subdirectories. Lists size of all files in the current directory. Gives disk use for each directory and all its subdirectories. Recursively searches a directory for big files. For additional information, consult the respective man pages. If you need additional space, please submit your request to commands below can show you how disk space you are consuming.
