NAME
     test - check file types and compare values

SYNOPSIS
     test EXPRESSION
     test EXPRESSION ]
     test OPTION

DESCRIPTION
     Exit with the status determined by EXPRESSION.

     --help
          display this help and exit

     --version
          output version information and exit

     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

     -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

     -k FILE
          FILE exists and has its sticky bit set

     -L FILE
          FILE exists and is a symbolic link

     -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 is readable

     -s FILE
          FILE exists and has a size greater than zero

     -S FILE
          FILE exists and is a socket

     -t [FD]
          file descriptor FD (stdout by default) is opened  on  a
          terminal

     -u FILE
          FILE exists and its set-user-ID bit is set

     -w FILE
          FILE exists and is writable

     -x FILE
          FILE exists and is executable

     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.
