test
Description
test checks for various properties of files, strings, and integers. It does not produce
any output other than error messages, but returns the result of the test as the exit
status.
The command line is a Boolean expression. The simplest expression is a string that
is true if the string is nonempty (that is, has nonzero length). More complex
expressions are composed of operators and operands, each of which is a separate
argument (that is, surrounded by white space). The operators imply the number and
type of their operands. The operators taking a file operand evaluate as false
(without error) if the file does not exist.
The following is a list of recognized operands:
–Aa file
True if file has an extended access ACL entry.
–Ad file
True if file is a directory with a directory default ACL.
–Af file
True if file is a directory with a file default ACL.
–b file True if file is a block special file (block special files are not supported)
–B file True if the file is tagged as binary (not text)
–c file True if file is a character special file
–d file True if file is a directory
–e file True if file exists
–Ea file
True if the file has the APF extended attribute
–Ep file
True if the file has the program control extended attribute
–Es file
True if the file has the shared address space extended attribute
–El file
True if the file has the shared library extended attribute
–f file True if file is an ordinary file
–g file True if the set-group-ID attribute of file is on
–h file True if file is a symbolic link
–k file True if the “sticky” bit is on file is on
–L file True if file is a symbolic link
–Ma file
True if the file has any Multilevel Security seclabel.
–n string
True if the length of string is greater than zero
–p file True if file is a FIFO (named pipe)
–r file True if file is readable (based on the security product’s check against the
effective user/group)
