Unable to defrag NTFS USB drive on Linux

Long Vu 05/11/2016

I got this error on Ubuntu 16.04:

[[email protected]:12 12:47:29 linux_utils]$ sudo ./udefrag -om /dev/sdc1
[sudo] password for lvu:
sudo: unable to execute ./udefrag: No such file or directory
[[email protected]:12 12:53:38 linux_utils]$

USB drive was created using Easy2Boot_v1.86DPMS.zip.

I used 'sudo bash ./fmt_ntfs.sh' to create the drive initially.

Then I copy over some .iso.
