Why not do it through a short python script? Something like (not tested)
import os
for dirpath, dirnames, filenames in os.walk('damagedfilesystem'):
for fn in filenames:
if fn.endswith('.txt'):
new_fn = fn.replace('.txt','-fixed.txt')
out_fh = open(new_fn,'w')

I often have damaged text files (due to a lovely storage system). The files
are of different formats, although I can usually assume they contain

Every once in a while, the lovely destruction (ahmstorage) system

can you provide a example of a bad lines and how do you like them to look
like after you fix them ?

I see that I'm late to the discussion and that your original problem has
morphed a bit. Maybe the simplest and oldest solution is the `tr -d'
command. See `man tr'.

The bad data is NULLs (I did not have hexedit, but was introduced to
hexedit mode in emacs which proved useful).
In the meantime, Muli Ben-Yehuda suggested to prevent the mess to begin
with. The corrupted file is the output of a C program. The problem is that
the program continues writing to the
+1 for tr -d '\0' file newfile, based on the updated description.
But prevention is better than a cure - find a way to avoid this in the
first place.

Read the original question again. She needs to eliminate the entire line
where a corruption
tr does what strings does - clears only the characters, not the full bad
line. Not what I wanted.
but now that I know what data I have there, I can clear it using any script
(back to Dov's solution).
Thanks everyone!

Hi,
Possibly using strings file_name new_file_name command could resolve
this problem.
Thank you.
