[msk na localhost d]$ file *.tar.bz2
fifo.tar.bz2:            bzip2 compressed data, block size = 900k
normal.tar.bz2:          bzip2 compressed data, block size = 900k
pipe-nonverbose.tar.bz2: bzip2 compressed data, block size = 900k
pipe.tar.bz2:            bzip2 compressed data, block size = 900k

Skusil som odmazat tie nuly na konci u jedneho suboru:

[msk na localhost d]$ cp pipe.tar.bz2 delme.tar.bz2

[msk na localhost d]$ khexedit

[msk na localhost d]$ md5sum *.tar.bz2
70e16b7379030665926ff8675c43d285  delme.tar.bz2
2618b8f47625c8cbcc14ef0f89107ca9  fifo.tar.bz2
70e16b7379030665926ff8675c43d285  normal.tar.bz2
2618b8f47625c8cbcc14ef0f89107ca9  pipe-nonverbose.tar.bz2
2618b8f47625c8cbcc14ef0f89107ca9  pipe.tar.bz2

Takze binarne su identicke, az na tych neviem kolko nulovych bajtov na konci. 
Pochopil by som to u blokoveho zariadenia, ale pipe je charracter device, ak 
ma pamat nemyli.
