  Hi! I wanna to scan file system finding size of each file, added "try" for files like /proc/..., but after first except it always gives 0.

  import os, re
  var fsz: BiggestInt
  
  for file in walkDirRec "/":
    if file.match re".*":
      try:
        fsz = getFileSize file
      except:
        echo file, " " ,0
      finally:
        echo file, " " ,fsz
  Run

  What am I doing wrong?

  Nothing, I think. There is probably some Unix/Linux system call to figure out in their swanky "everything is a file" design whether something really is a file or not.

  Araq, from my understanding of his question, his problem is, that after the first exeption has occured, all subsequent output for file size is 0. That would be strange. An explanation would be that proc getFileSize() has an internal error state, so that it returns always 0 after first call with invalid argument (). That would be strange. Or the always zero result could be a result of the try/except construct, what would be also strange. Maybe we have to test his code to find out.

  I was able to run this code on the forum, using the run button and it works fine.
