isblockdev

isblockdev(path) -> Bool

Returns true if path is a block device, false otherwise.

Examples

  1. Check if a path is a block device:

    julia> isblockdev("/dev/sda")
true

    This example checks if the path "/dev/sda" is a block device.

  2. Handle non-block device path:

    julia> isblockdev("/dev/null")
false

    It returns false for a non-block device path like "/dev/null".

  3. Use with a variable: 
    julia> path = "/dev/sda";
julia> isblockdev(path)
true

    The function can also be used with a variable containing the path.

Common mistake example:

julia> isblockdev("/path/to/nonexistent")
ERROR: IOError: could not determine type of file "/path/to/nonexistent"

In this example, the function throws an IOError because the provided path does not exist. Make sure to provide a valid path to avoid such errors.
