EXTRA

       Exit with the status determined by EXPRESSION.

       An  omitted EXPRESSION defaults to false.  Otherwise, EXPRESSION is true or false and sets
       exit status.

       It is one of:

       *   (    EXPRESSION    )                  EXPRESSION    is    true    *    !    EXPRESSION
       EXPRESSION  is  false  * EXPRESSION1 -a EXPRESSION2   both EXPRESSION1 and EXPRESSION2 are
       true * EXPRESSION1 -o EXPRESSION2   either EXPRESSION1 or EXPRESSION2 is true

       String operations: * -n STRING             the  length  of  STRING  is  nonzero  *  STRING
       equivalent  to  -n  STRING * -z STRING            the length of STRING is zero * STRING1 =
       STRING2    the strings are equal * STRING1 != STRING2   the strings are not equal

       Integer comparisons: * INTEGER1 -eq INTEGER2   INTEGER1 is equal to  INTEGER2  *  INTEGER1
       -ge  INTEGER2    INTEGER1  is  greater  than  or equal to INTEGER2 * INTEGER1 -gt INTEGER2
       INTEGER1 is greater than INTEGER2 * INTEGER1 -le INTEGER2   INTEGER1 is less than or equal
       to  INTEGER2  *  INTEGER1  -lt  INTEGER2    INTEGER1  is less than INTEGER2 * INTEGER1 -ne
       INTEGER2   INTEGER1 is not equal to INTEGER2

       File operations: * FILE1 -ef FILE2   FILE1 and  FILE2  have  the  same  device  and  inode
       numbers  *  FILE1  -nt  FILE2    FILE1 is newer (modification date) than FILE2 * FILE1 -ot
       FILE2   FILE1 is older than FILE2

       * -b FILE     FILE exists and is block special * -c FILE     FILE exists and is  character
       special  *  -d FILE     FILE exists and is a directory * -e FILE     FILE exists * -f FILE
       FILE exists and is a regular file * -g FILE     FILE exists and is set-group-ID * -G  FILE
       FILE  exists  and  is  owned  by the effective group ID * -h FILE     FILE exists and is a
       symbolic link (same as -L) * -k FILE     FILE exists and has its sticky bit set * -L  FILE
       FILE  exists  and  is  a symbolic link (same as -h) * -N FILE     FILE exists and has been
       modified since it was last read * -O FILE     FILE exists and is owned  by  the  effective
       user  ID  * -p FILE     FILE exists and is a named pipe * -r FILE     FILE exists and read
       permission is granted * -s FILE     FILE exists and has a size greater than zero * -S FILE
       FILE  exists and is a socket * -t FD       file descriptor FD is opened on a terminal * -u
       FILE     FILE exists and its set-user-ID bit is set * -w FILE     FILE  exists  and  write
       permission  is  granted  *  -x  FILE     FILE exists and execute (or search) permission is
       granted

       Except for -h and -L, all FILE-related tests dereference (follow) symbolic links.   Beware
       that  parentheses  need to be escaped (e.g., by backslashes) for shells.  INTEGER may also
       be -l STRING, which evaluates to the length of STRING.

       NOTE: Binary -a and -o are inherently ambiguous.  Use test EXPR1 &&  test  EXPR2  or  test
       EXPR1 || test EXPR2 instead.

       NOTE:  [  honors the --help and --version options, but test does not.  test treats each of
       those as it treats any other nonempty STRING.

       NOTE: your shell may have its own version of test and/or [, which usually  supersedes  the
       version  described here.  Please refer to your shell's documentation for details about the
       options it supports.
