−−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.
