How To Fix sd-engf: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu sd-engf is provided by snowdrop package.

snowdrop is:

Snowdrop provides reliable, difficult to remove steganographic watermarking of text documents (internal memos, draft research papers, advisories and other writing) and C sources (limited distribution software, licensed software, or freely available code) so that: (1) leaks can be identified if the data goes public. (2) original source can be determined and demonstrated if part of the document is claimed by somebody else, copied without permission, etc. Snowdrop uses redundant steganography using four different logical channels, and should be proof to many modifications, including reformatting, spell checking and so on.

This package is useful in forensic investigations and security actions. It provides three commands: sd-eng, sd-engf and sd-c. sd-eng and sd-engf provide watermarking for draft-quality and fine-quality English language text documents, respectively, whereas sd-c provides experimental C source code watermarking.

Warning: Snowdrop is currently in beta, and may produce bad or corrupted results, especially when run on C source code.

To fix this problem, we can install more using the command below.

sudo apt-get -y install snowdrop

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install snowdrop.

sudo apt -y install snowdrop

Or if you have aptitude installed you can use the following command.

sudo aptitude install snowdrop
