TEST(1B) BSD System Compatibility TEST(1B)

test - (BSD) condition command

/usr/local/heirloom/usr/ucb/test [expr]

test evaluates the expression expr, and if its value is true then returns zero exit status; otherwise, a non zero exit status is returned. test returns a non zero exit if there are no arguments.

The following primitives are used to construct expr:

-r file
true if the file exists and is readable.
-w file
true if the file exists and is writable.
-u file
true if the file exists and has the setuid bit set.
-g file
true if the file exists and has the setgid bit set.
-k file
true if the file exists and has the sticky bit set.
-f file
true if the file exists and is not a directory.
-d file
true if the file exists and is a directory.
-h file
true if the file exists and is a symbolic link.
-L file
true if the file exists and is a symbolic link.
-p file
true if the file exists and is a named pipe.
-b file
true if the file exists and is a block device.
-c file
true if the file exists and is a character device.
-s file
true if the file exists and has a size greater than zero.
-t [fildes]
true if the open file whose file descriptor number is fildes (1 by default) is associated with a terminal device.
-z s1
true if the length of string s1 is zero.
-n s1
true if the length of the string s1 is nonzero.
s1 = s2
true if the strings s1 and s2 are equal.
s1 != s2
true if the strings s1 and s2 are not equal.
s1
true if s1 is not the null string.
n1 -eq n2
true if the integers n1 and n2 are algebraically equal. Any of the comparisons -ne, -gt, -ge, -lt, or -le may be used in place of -eq.

These primaries may be combined with the following operators:

!
unary negation operator
-a
binary and operator
-o
binary or operator
( expr )
parentheses for grouping.

-a has higher precedence than -o. Notice that all the operators and flags are separate arguments to test. Notice also that parentheses are meaningful as command separators and must be escaped.
