attr - Get or set attributes for files

Synopsis

attr [ -hp ] file [ attribute [ =value ] ... ]

Description

The attr utility gets or sets attributes for the object specified by file. When no attributes are specified, attr displays all of the attributes for the object in a re-entrable format to standard output. When an attribute is specified, attr displays the value of the attribute to standard output. When an attribute and value are specified, attr sets the attribute to the value. Note that all attributes can be displayed, but only some attributes can be set.

For date and time attributes, the value display by default is formatted with the asctime() function. To display dates and times in a different format, set the LC_TIME environment variable to the path of a locale that defines the desired format. The dates and times will be displayed in the format defined by the d_t_fmt keyword in the LC_TIME section of the locale. See the example on locale programming for more information on displaying locale source and creating locales. Example: export -s LC_TIME=/QSYS.LIB/EN_US.LOCALE

Options

-h
Display or set the attributes of a symbolic link instead of the object pointed to by the symbolic link.
-p
Display the attribute in an re-entrable format.
