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, EXPRES-
     SION 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

User Commands                                             TEST(1)



     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

User Commands                                             TEST(1)



          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 backslashes) 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 usually supersedes the version described here.  Please
     refer to your shell's documentation for  details  about  the
     options it supports.
