Q: I would like to cover bash in a course I will soon be teaching. May I use these materials for my course, provided the source is cited? Thanks for this excellent work, btw. Absolutely. Perhaps we should consider putting a license on these documents. Creative commons something perhaps. - [[Lhunath]] Q. The following suggestion can be harmful: echo 'PATH="$HOME/bin:$PATH"' >> "$HOME/.bashrc" If someone places a script named 'ls' in the bin directory of $HOME, you would be running it every time you typed 'ls', instead of running the builtin 'ls'. This can be harmful. I suggest echo 'PATH="$PATH:$HOME/bin"' >> "$HOME/.bashrc" It is not harmful. Anyone with write access to ~/bin will generally have write access to ~/.bashrc, so there is no additional loss of security here. The original proposal also allows the user to wrap standard utilities, which yours cannot (in fact, that exactly why you proposed it). I believe being able to wrap utilities can be very useful. - [[Lhunath]] Feedback: I could not understand the HereDocument page (found another source that helped) and I think the page could do with working examples and a more thorough explantion. Rest of course is wonderful though, I learn so much today, thanks :) |
This page is for any feedback on the BashGuide. Feel free to ask any questions you want.
