Contribution License Agreement

This Contribution License Agreement ("Agreement") governs your Contribution(s) (as defined below) and conveys certain license rights to Fox-IT B.V. ("Fox-IT") for your Contribution(s) to Fox-IT"s open source Dissect project. This Agreement covers any and all Contributions that you ("You" or "Your"), now or in the future, Submit (as defined below) to this project. This Agreement is between Fox-IT B.V. and You and takes effect when you click an “I Accept” button, check box presented with these terms, otherwise accept these terms or, if earlier, when You Submit a Contribution.

1. Definitions.
   "Contribution" means any original work of authorship, including any modifications or additions to an existing work, that is intentionally submitted by You to Fox-IT for inclusion in, or documentation of, any of the software products owned or managed by, or on behalf of, Fox-IT as part of the Project (the "Work").
   "Project" means any of the projects owned or managed by Fox-IT and offered under a license approved by the Open Source Initiative (www.opensource.org).
   "Submit" means any form of electronic, verbal, or written communication sent to Fox-IT or its representatives, including but not limited to communication on electronic mailing lists, source code control systems, and issue tracking systems that are managed by, or on behalf of, Fox-IT for the purpose of discussing and improving the Work, but excluding communication that is conspicuously marked or otherwise designated in writing by You as "Not a Contribution."

2. Grant of Copyright License. Subject to the terms and conditions of this Agreement, You hereby grant to Fox-IT and to recipients of software distributed by Fox-IT a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, sublicense, and distribute Your Contributions and such derivative works.

3. Grant of Patent License. Subject to the terms and conditions of this Agreement, You hereby grant to Fox-IT and to recipients of software distributed by Fox-IT a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, maintain, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by You that are necessarily infringed by Your Contribution(s) alone or by combination of Your Contribution(s) with the Work to which such Contribution(s) was submitted. If any entity institutes patent litigation against You or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that your Contribution, or the Work to which you have contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.

4. Representations. You represent that:

   • You are legally entitled to grant the above license.
   • each of Your Contributions is Your original creation (see section 8 for submissions on behalf of others).
   • Your Contribution submissions include complete details of any third-party license or other restriction (including, but not limited to, related patents and trademarks) of which you are personally aware and which are associated with any part of Your Contributions.

5. Employer. If Your Contribution is made in the course of Your work for an employer or Your employer has intellectual property rights in Your Submission by contract or applicable law, You must secure permission from Your employer to make the Contribution before signing this Agreement. In that case, the term "You" in this Agreement will refer to You and the employer collectively. If You change employers in the future and desire to Submit additional Contribution for the new employer, then You agree to sign a new Agreement and secure permission from the new employer before Submitting those Contributions.

6. Support. You are not expected to provide support for Your Contribution, unless You choose to do so. Any such support provided to the Project is provided free of charge.

7. Warranty. Unless required by applicable law or agreed to in writing, You provide Your Contributions on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE.

8. Third party material. Should You wish to submit work that is not Your original creation, You may only submit it to Fox-IT separately from any Contribution, identifying the complete details of its source and of any license or other restriction (including, but not limited to, related patents, trademarks, and license agreements) of which You are personally aware, and conspicuously marking the work as "Submitted on behalf of a third-party: [named here]".

9. Notify. You agree to notify Fox-IT of any facts or circumstances of which You become aware that would make the above representations inaccurate in any respect.

[mnrkbys]

I was very busy and could not fix it for a while.
Now, I have modified the code according to the comments.

[Schamper]

Thanks! Just some small stylistic suggestions. Could you also rebase on the latest main branch?

[mnrkbys]

Thanks for your comment.
I have updated shell.py again and rebased on the latest main.
