File sys- + tems shall be specified by the file operands; when none + are specified, information shall be written for all file + systems. The format of the default output from df is + unspecified, but all space figures are reported in + 512-byte units, unless the -k option is specified. This + output shall contain at least the file system names, + amount of available space on each of these file systems, + and the number of free file slots, or inodes, avail- + able; when -t is specified, the output shall contain the + total allocated space as well. + +OPTIONS + The df utility shall conform to the Base Definitions + volume of IEEE Std 1003.1-2001, Section 12.2, Utility + Syntax Guidelines. + + The following options shall be supported: + + -k Use 1024-byte units, instead of the default + 512-byte units, when writing space figures. + + -P Produce output in the format described in the + STDOUT section. + + -t Include total allocated-space figures in the out- + put. + + +OPERANDS + The following operand shall be supported: + + file A pathname of a file within the hierarchy of the + desired file system. If a file other than a + FIFO, a regular file, a directory, or a special + file representing the device containing the file + system (for example, /dev/dsk/0s1) is specified, + the results are unspecified. Otherwise, df shall + write the amount of free space in the file system + containing the specified file operand. + + +STDIN + Not used. + +INPUT FILES + None. + +ENVIRONMENT VARIABLES + The following environment variables shall affect the + execution of df: + + LANG Provide a default value for the + internationalization variables that are unset or + null. (See the Base Definitions volume of + IEEE Std 1003.1-2001, Section 8.2, International- + ization Variables for the precedence of interna- + tionalization variables used to determine the + values of locale categories.) + + LC_ALL If set to a non-empty string value, override the + values of all the other internationalization + variables. + + LC_CTYPE + Determine the locale for the interpretation of + sequences of bytes of text data as characters + (for example, single-byte as opposed to multi- + byte characters in arguments). + + LC_MESSAGES + Determine the locale that should be used to + affect the format and contents of diagnostic mes- + sages written to standard error and informative + messages written to standard output. + + NLSPATH + Determine the location of message catalogs for + the processing of LC_MESSAGES . + + +ASYNCHRONOUS EVENTS + Default. + +STDOUT + When both the -k and -P options are specified, the fol- + lowing header line shall be written (in the POSIX + locale): + + + "Filesystem 1024-blocks Used Available Capacity Mounted on\n" + + When the -P option is specified without the -k option, + the following header line shall be written (in the POSIX + locale): + + + "Filesystem 512-blocks Used Available Capacity Mounted on\n" + + The implementation may adjust the spacing of the header + line and the individual data lines so that the informa- + tion is presented in orderly columns. + + The remaining output with -P shall consist of one line + of information for each specified file system. These + lines shall be formatted as follows: + + + "%s %d %d %d %d%% %s\n", , , + , , , + + + In the following list, all quantities expressed in + 512-byte units (1024-byte when -k is specified) shall be + rounded up to the next higher unit. The fields are: + + + + The name of the file system, in an implementa- + tion-defined format. + + + The total size of the file system in 512-byte + units. The exact meaning of this figure is imple- + mentation-defined, but should include + , , plus any space + reserved by the system not normally available to + a user. + + + The total amount of space allocated to existing + files in the file system, in 512-byte units. + + + The total amount of space available within the + file system for the creation of new files by + unprivileged users, in 512-byte units. When this + figure is less than or equal to zero, it shall + not be possible to create any new files on the + file system without first deleting others, unless + the process has appropriate privileges. The fig- + ure written may be less than zero. + + + + The percentage of the normally available space + that is currently allocated to all files on the + file system. This shall be calculated using the + fraction: + + + /( + ) + + expressed as a percentage. This percentage may be + greater than 100 if is less than zero. The + percentage value shall be expressed as a positive inte- + ger, with any fractional result causing it to be rounded + to the next highest integer. + + + + The directory below which the file system hierar- + chy appears. + + + The output format is unspecified when -t is used. + +STDERR + The standard error shall be used only for diagnostic + messages. + +OUTPUT FILES + None. + +EXTENDED DESCRIPTION + None. + +EXIT STATUS + The following exit values shall be returned: + + 0 Successful completion. + + >0 An error occurred. + + +CONSEQUENCES OF ERRORS + Default. + + The following sections are informative. + +APPLICATION USAGE + On most systems, the "name of the file system, in an + implementation-defined format" is the special file on + which the file system is mounted. + + On large file systems, the calculation specified for + percentage used can create huge rounding errors. + +EXAMPLES + The following example writes portable information about + the /usr file system: + + + df -P /usr + + Assuming that /usr/src is part of the /usr file system, + the following produces the same output as the previous + example: + + + df -P /usr/src + +RATIONALE + The behavior of df with the -P option is the default + action of the 4.2 BSD df utility. The uppercase -P was + selected to avoid collision with a known industry exten- + sion using -p. + + Historical df implementations vary considerably in their + default output. It was therefore necessary to describe + the default output in a loose manner to accommodate all + known historical implementations and to add a portable + option ( -P) to provide information in a portable for- + mat. + + The use of 512-byte units is historical practice and + maintains compatibility with ls and other utilities in + this volume of IEEE Std 1003.1-2001. This does not man- + date that the file system itself be based on 512-byte + blocks. The -k option was added as a compromise measure. + It was agreed by the standard developers that 512 bytes + was the best default unit because of its complete his- + torical consistency on System V (versus the mixed + 512/1024-byte usage on BSD systems), and that a -k + option to switch to 1024-byte units was a good compro- + mise. Users who prefer the more logical 1024-byte quan- + tity can easily alias df to df -k without breaking many + historical scripts relying on the 512-byte units. + + It was suggested that df and the various related utili- + ties be modified to access a BLOCKSIZE environment vari- + able to achieve consistency and user acceptance. Since + this is not historical practice on any system, it is + left as a possible area for system extensions and will + be re-evaluated in a future version if it is widely + implemented. + +FUTURE DIRECTIONS + None. + +SEE ALSO + find + +COPYRIGHT + Portions of this text are reprinted and reproduced in + electronic form from IEEE Std 1003.1, 2003 Edition, + Standard for Information Technology -- Portable Operat- + ing System Interface (POSIX), The Open Group Base Speci- + fications Issue 6, Copyright (C) 2001-2003 by the Insti- + tute of Electrical and Electronics Engineers, Inc and + The Open Group.
