.SH DESCRIPTION
.\" Add any additional description here
.PP
Exit with the status determined by EXPRESSION.
.TP
\fB\-\-help\fR
display this help and exit
.TP
\fB\-\-version\fR
output version information and exit
.PP
An omitted EXPRESSION defaults to false.  Otherwise,
EXPRESSION is true or false and sets exit status.  It is one of:
.TP
( EXPRESSION )
EXPRESSION is true
.TP
! EXPRESSION
EXPRESSION is false
.TP
EXPRESSION1 \fB\-a\fR EXPRESSION2
both EXPRESSION1 and EXPRESSION2 are true
.TP
EXPRESSION1 \fB\-o\fR EXPRESSION2
either EXPRESSION1 or EXPRESSION2 is true
.TP
\fB\-n\fR STRING
the length of STRING is nonzero
.TP
STRING
equivalent to \fB\-n\fR STRING
.TP
\fB\-z\fR STRING
the length of STRING is zero
.TP
STRING1 = STRING2
the strings are equal
.TP
STRING1 != STRING2
the strings are not equal
.TP
INTEGER1 \fB\-eq\fR INTEGER2
INTEGER1 is equal to INTEGER2
.TP
INTEGER1 \fB\-ge\fR INTEGER2
INTEGER1 is greater than or equal to INTEGER2
.TP
INTEGER1 \fB\-gt\fR INTEGER2
INTEGER1 is greater than INTEGER2
.TP
INTEGER1 \fB\-le\fR INTEGER2
INTEGER1 is less than or equal to INTEGER2
.TP
INTEGER1 \fB\-lt\fR INTEGER2
INTEGER1 is less than INTEGER2
.TP
INTEGER1 \fB\-ne\fR INTEGER2
INTEGER1 is not equal to INTEGER2
.TP
FILE1 \fB\-ef\fR FILE2
FILE1 and FILE2 have the same device and inode numbers
.TP
FILE1 \fB\-nt\fR FILE2
FILE1 is newer (modification date) than FILE2
.TP
FILE1 \fB\-ot\fR FILE2
FILE1 is older than FILE2
.TP
\fB\-b\fR FILE
FILE exists and is block special
.TP
\fB\-c\fR FILE
FILE exists and is character special
.TP
\fB\-d\fR FILE
FILE exists and is a directory
.TP
\fB\-e\fR FILE
FILE exists
.TP
\fB\-f\fR FILE
FILE exists and is a regular file
.TP
\fB\-g\fR FILE
FILE exists and is set\-group\-ID
.TP
\fB\-G\fR FILE
FILE exists and is owned by the effective group ID
.TP
\fB\-h\fR FILE
FILE exists and is a symbolic link (same as \fB\-L\fR)
.TP
\fB\-k\fR FILE
FILE exists and has its sticky bit set
.TP
\fB\-L\fR FILE
FILE exists and is a symbolic link (same as \fB\-h\fR)
.TP
\fB\-N\fR FILE
FILE exists and has been modified since it was last read
.TP
\fB\-O\fR FILE
FILE exists and is owned by the effective user ID
.TP
\fB\-p\fR FILE
FILE exists and is a named pipe
.TP
\fB\-r\fR FILE
FILE exists and read permission is granted
.TP
\fB\-s\fR FILE
FILE exists and has a size greater than zero
.TP
\fB\-S\fR FILE
FILE exists and is a socket
.TP
\fB\-t\fR FD
file descriptor FD is opened on a terminal
.TP
\fB\-u\fR FILE
FILE exists and its set\-user\-ID bit is set
.TP
\fB\-w\fR FILE
FILE exists and write permission is granted
.TP
\fB\-x\fR FILE
FILE exists and execute (or search) permission is granted
.PP
Except for \fB\-h\fR and \fB\-L\fR, all FILE\-related tests dereference symbolic links.
Beware that parentheses need to be escaped (e.g., by backslashes) for shells.
INTEGER may also be \fB\-l\fR STRING, which evaluates to the length of STRING.
.PP
NOTE: Binary \fB\-a\fR and \fB\-o\fR are inherently ambiguous.  Use 'test EXPR1 && test
EXPR2' or 'test EXPR1 || test EXPR2' instead.
.PP
NOTE: [ honors the \fB\-\-help\fR and \fB\-\-version\fR options, but test does not.
test treats each of those as it treats any other nonempty STRING.
.PP
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.
