Increasing in difficulty, this challenge presents 20 directories with many different files residing within each.  Passing the ‘find’ command enables us to search the current directory for files 1033 bytes in size that are not executable.

  1. I was on my right way. what i tried was: file . -name *file* -size 1033b, but this gave me an error:
    find: unknown predicate `-file2′

    What I don’t understand why do you use c in 1033c, shouldn’t it be 1033b, b for Bytes???

  2. Hi t0v4,

    Thanks for commenting. If you look into the man-page for the find command, it’ll give you a readout of the different character shortcuts for file size.

    “`b’ for 512-byte blocks (this is the default if no suffix is used)

    `c’ for bytes”
