| Dec 23, 2012 at 1:03 | comment | added | Emanuel Berg | OK, I see, haha :) The purpose of the script, if you check out the link in the first comment, is to create a text file with some info on the system. I'll refer to that file when someone asks for example "What window manager do you use?", also, I print the commands so that that person can see not only the information, but also the exact way by which I got it. | |

| Dec 23, 2012 at 0:41 | comment | added | watael | ah, ok! you misunderstood me: you don't waste my time, you uselessly occupy the resources of the machine for printing such informations. | |
| Dec 23, 2012 at 0:26 | comment | added | Emanuel Berg | What on earth are you talking about?! 1. The script works exactly as intended with the eval solution, 2. ... which I thanked, if you read the comment above, 3. the moderators frequently remove greetings, so I've stopped using them, although I fail to see how that's a big issue, and 4. do you actually expect me to thank you after calling my question silly, and my wish to print information "a waste of time"? | |
| Dec 23, 2012 at 0:14 | comment | added | watael | You ask. I answer. The answer is an opinion on how things should be handled, instead of your non-working, and counter-productive idea. Q&A can also show what are best practices, and tell what are worst. btw: no "hi", no "please", no "thanks"... do you think we owe you something? learn to live with others, that'll improve your coding too. | |
| Dec 22, 2012 at 23:35 | comment | added | Emanuel Berg | @UlrichDangel: When I said I needed it, that referred to a general solution, as opposed to individual functions for all commands. As for eval, I don't know how that differs from backticks/$(), but if you care to explain why it is considered unsafe, sure, I'll change it. | |

| Dec 22, 2012 at 23:23 | comment | added | Emanuel Berg | You can take a look at the script in which I need this. So you see, individual functions is not an option. As for what you think is silly or not, that's irrelevant as this is a Q&A site. Downvote. | |
