NAME
       test - check file types and compare values
SYNOPSIS
       test EXPRESSION
       test
       [ EXPRESSION ]
       [ ]
       [ OPTION
DESCRIPTION
       Exit with the status determined by EXPRESSION.
       --help display this help and exit
       --version
              output version information and exit
       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
       -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
       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
       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)
       -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  symbolic
       links.   Beware  that  parentheses  need  to be escaped (e.g., by back-
       slashes) for shells.  INTEGER may also be -l STRING, which evaluates to
       the length of STRING.
       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  usu-
       ally  supersedes  the  version  described  here.   Please refer to your
       shell's documentation for details about the options it supports.
