Redirecting output from command in interactive PeepDF session creates hundreds of files (1 for each byte of output!)

[KurtPfeifle]

I came across this issue when playing with the current PeepDF code from the Git repo....

You can use this sample PDF file (handcoded by me) to reproduce the issue of this report:

The following is from an interactive peepdf session (I know I haven't installed PyV8 and pylibemu on this system, but this shouldn't matter for this issue):

Leaving the Peepdf interactive console...Bye! ;)

Now look at the file(s) named stream9.ahx created by the last PeepDF command with its output re-directed:

kp@mbp:mrmcd15>  ls -l stream9.ahx_* | wc -l

Each output file contains exactly 1 Byte. (Concatenating these file in the correct order will give the same output as seen in the interactive PeepDF session without re-directing the output.)

I also tried this command variation for re-directing the output: filters 9 ahx >> stream9.ahx.

But it doesn't make a difference.

@KurtPfeifle, this should be fixed ;) Thanks!
