test

TEST(1) 						      General Commands Manual							   TEST(1)

NAME

       test, [ - test for a condition

SYNOPSIS

       test expr
       [ expr ]

OPTIONS

       (none)

EXAMPLES

       test -r file	   # See if file is readable

DESCRIPTION

       Test checks to see if files exist, are readable, etc. and returns an exit status of zero if true and nonzero if false.  The legal operators
       are

	    -r file   true if the file is readable
	    -w file   true if the file is writable
	    -x file   true if the file is executable
	    -f file   true if the file is not a directory
	    -d file   true if the file is a directory
	    -s file   true if the file exists and has a size > 0
	    -t fd     true if file descriptor fd (default 1) is a terminal
	    -z s      true if the string s has zero length
	    -n s      true if the string s has nonzero length
	    s1 = s2   true if the strings s1 and s2 are identical
	    s1 != s2  true if the strings s1 and s2 are different
	    m -eq m   true if the integers m and n are numerically equal
       The operators -gt, -ge, -ne, -le, and -lt may be used as well.  These operands may be combined with -a (Boolean and), -o  (Boolean  or),  !
       (negation).  The priority of -a is higher than that of -o.  Parentheses are permitted, but must be escaped to keep the shell from trying to
       interpret them.
