Hi I was trying to unzip a folder in UnRAID 6.2.4 (in terminal using "unzip [file path]") and got the error;

bash: /usr/bin/unzip: cannot execute binary file: Exec format error

and from what I can find that error is normally for when you are trying to run a 32 bit program on a 64 bit os.

 

Is there a fix for this, or a new command??

 

unzip works for me on 6.3.2  You really should upgrade anyways.  But, beyond that maybe your bzimage / bzroot files are corrupted (or RAM errors).  Alternatively, possible you may have old packages that are being installed and overwriting the built-in.  (They'd be within /boot/extra or /boot/packages)
