Re: Does [ -f FILE ] have a bug on testing a symlink ?

[Jonathan Hankins]

$ touch foo

$ ln -s foo bar

$ [[ -f foo ]] && [[ ! -h foo ]] && echo "exists and is not a symlink"

exists and is not a symlink

$ [[ -f bar ]] && [[ ! -h bar ]] && echo "exists and is not a symlink" 

$

You're addressing different lines but I am saying this line is inaccurate, right?


-f FILE        True if file exists and is a regular file.


Is there really a simple regular file test existing?

    Evaluate conditional _expression_.

    Exits with a status of 0 (true) or 1 (false) depending on
    the evaluation of EXPR.  Expressions may be unary or binary.  Unary
    expressions are often used to examine the status of a file.  There
    are string operators and numeric comparison operators as well.

    The behavior of test depends on the number of arguments.  Read the
    bash manual page for the complete specification.
