comment non-root users can run passwd command as root, why can't they change password of root?
@edwardtorvalds OK, but that's not a valid example of it. And it's also not what your question was about. Sure, you can create a malicious anything if you have root access and then make it SUID. However, doing so requires root access so the danger is not so much in allowing SUID programs but in permitting users to obtain root access.

@edwardtorvalds yes, but to do that you need to already have root access so the point is moot. If you have root access you can do pretty much anything anyway.

comment Bash: #: command not found
@Otheus how else would the OP run pacman -Ss #? It has to be run from a shell.

comment Bash: #: command not found
@mikeserv yes, setting PS4 that way is a good trick (and probably deserves its own answer) but that produces (or can produce) a lot of output. I think it's far more likely that one of the startup files has a malformed line. If the OP tries this and it turns out not to be the case, we can investigate further. As for interactive shells, bash at least, does interpret comments. Try echo foo #bar. Same for non-interactive, try printf 'echo foo # bar' | bash. The file you're thinking of is probably ~/.inputrc but adding a \# (or #) there doesn't produce the error.

comment Bash: #: command not found
@Otheus no, pacman -Ss # just runs pacman -Ss. The # is treated as a comment and is ignored.

comment awk : parse and write to another file
Does this have to be awk? It really isn't the best tool for this sort of thing.

comment How to reach nm-connection-editor from the GUI in GNOME 3?
@LoukiosValentine79 It is often the case that what we write seems perfectly clear to us but is not clear at all to somebody else. If people don't understand your question, it is usually because the question is harder to understand than you think. Those users who take the time to leave a comment asking for clarification are doing so to help you. They don't get anything from it, they're just trying to make the question clearer to improve your chances of getting an answer. So, don't get angry, take their advice, clarify your question and improve your chances of getting an answer.

comment Add column to a CSV file as a function of other two columns, one from other file
OK, what value from b.csv? The first? The third? All of them? How can we know? You need to give us enough data so we can reproduce your test files and process them to get your desired output. So, please edit your question and add the necessary information.

comment Add column to a CSV file as a function of other two columns, one from other file
What comparison? Do you want to compare the last field of a.csv to the 1st field of b.csv? Which line of b.csv? What are "upper and lower fields"? Please edit your question and clarify what you need.

comment wkhtmltopdf & debian - install
We're going to need more information. Obviously, the laptop and VM are not identical but we can't know how. For starters, please edit your question and add the contents of /etc/apt/sources.list and of any files in /etc/apt/sources.list.d from each of the machines.

comment Finding Parent of a path in Unix
Please edit your question and explain what you need more clearly. What is $unix_linux? Where is this folder? What do you know about it?
