    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, 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: 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.
