df (abbreviation for disk free) is a standard Unix command used to display the amount of available disk space for file systems on which the invoking user has appropriate read access. df is typically implemented using the statfs or statvfs system calls .
mountpoint — Check whether the directory or device is a mountpoint. mv — Move files. nbd-client — Connect to an NBD server. nc/netcat — Forward stdin/stdout to a file or network connection. netstat — Display networking information. nice — Run a command line at an increased or decreased scheduling priority. nl — Number lines of input.
Filelight is a graphical disk usage analyzer part of the KDE Gear.. Instead of showing a tree view of the files within a partition or directory, or even a columns-represent-directories view like xdiskusage, it shows a series of concentric pie charts representing the various directories within the requested partition or directory and the amount of space they use.

du (abbreviated from disk usage) is a standard Unix program used to estimate file space usage—space used under a particular directory or files on a file system. A Windows commandline version of this program is part of Sysinternals suite by Mark Russinovich .
The system utility fsck (file system check) is a tool for checking the consistency of a file system in Unix and Unix-like operating systems, such as Linux, macOS, and FreeBSD. [1] The equivalent programs on MS-DOS and Microsoft Windows are CHKDSK, SFC, and SCANDISK.
On Windows NT operating systems, CHKDSK can also check the disk surface for bad sectors and mark them (in MS-DOS 6.x and Windows 9x, this is a task done by Microsoft ScanDisk). The Windows Server version of CHKDSK is RAID-aware and can fully recover data in bad sectors of a disk in a RAID-1 or RAID-5 array if other disks in the set are intact. [11]
The required disk space may be easily allocated on systems with more recent specifications (i.e. a system with 3 GB of memory having a 6 GB fixed-size page file on a 750 GB disk drive, or a system with 6 GB of memory and a 16 GB fixed-size page file and 2 TB of disk space).
Disk quotas are supported by most modern operating systems, including Unix-like systems, such as AIX (using JFS or JFS2 filesystem), Linux (using ext3, ext4, ext2, XFS (integrated support) among other filesystems), Solaris (using UFS or ZFS), Microsoft Windows starting with Windows 2000, Novell NetWare, VMS, and others.
