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 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.
