      Since a lot of this is guaranteed to be seen as arcane magic, maybe this is an opportune place for the UI hooks for a conversational/palette-based UI? Maybe >> to set it off?

    1. unbuffer disables the output buffering that occurs when program output is redirected. For example, suppose you are watching the output from a fifo by running it through od and then more.    od -c /tmp/fifo | more You will not see anything until a full page of output has been produced. You can disable this automatic buffering as follows:    unbuffer od -c /tmp/fifo | more
    1. The command also can be run in silent mode (tty -s) where no output is produced, and the command exits with an appropriate exit status.

    1. I find it convenient to change proxy and other settings through gui window by right-clicking on launcher icon on my desktop. I mostly start slack by clicking desktop launcher, but also want to be able to start it from command line in some cases.
    2. If you really want this, I suggest you write a little function that extracts the executable name from the .desktop file and runs it. Add these lines to your shell's initialization file (e.g. ~/.bashrc): runDesktop () { eval "$(awk -F= '$1=="Exec"{$1=""; print}' "$1")" } Then, you can run your .desktop file with runDesktop ~/Desktop/slack.desktop
    1. We could add heuristics like: is the file inside XDG_DATA_DIRS/applications? if not, is the file inside XDG_DATA_HOME/applications? if not, is the file marked as executable? if not, open with the text editor
    2. Hello , since I made a modification in gio-tool (#2098 (closed)) , I seen this issue and decide to give it go. I implemented an unix only solution only for launching a desktop file through gio command, see !1779 (merged)
    3. When one is searching for it on the internet, there are many many people wondering how one can open .desktop files. It seems trivial, since one usually just has to click an item on the launcher so one thinks there must be some way.
    4. I have to agree with Raphael here that this should probably be handled in gnome-open, its a pain to have to implement .desktop parsing code in every beagle front end when I can't really think of an instance where the expected behavior wouldn't be to execute the associated command.
    5. I don't know what nautilus does, but i think when you double click a .desktop file it launches the associated program, i guess they don't use gnome-open then..
    6. deskbar should probably detect their extension and execute the relevant command as opposed to opening the file for editing.

    1. For example, on the terminal I'm using, the right arrow outputs ^[[C. You can see what sequence your terminal outputs by pressing Ctrl-V Right Arrow. The same is true for other cursor-control keys such as Page Up and End.

    1. I debugged docker-compose and docker-py and figured out that you should either use environment variables or options in command. You should not mix these . If you even specify --tls in command then you will have to specify all the options as the TLSConfig object, as now TLSConfig object is created completely from the command options and operide the TFSConfig object created from the environment variable.

    1. I had never considered it that in nearly a decade of using GNU find! Thank you for that! It will definitely change the way I think about -prune from now on.
    2. I think this structure is much easier and correlates to the right approach
    3. it isn't actually -prune itself that causes this, by the way. The issue is that the or operator "short-circuits", and or has lower precedence than and. The end result is that if a file called .snapshot is encountered it will match the first -name, -prune will then do nothing (but return true), and then the or returns true since its left-argument was true. The action (eg: -print) is part of its second argument, so it never has a chance to execute.
    4. If all you want to do is print the results you might be used to leaving out the -print action. You generally don't want to do that when using -prune.
    5. which means that it'll also print out the name of the directory you're pruning, which usually isn't what you want. Instead it's better to explicitly specify the -print action if that's what you want
    6. The thing I'd found confusing about -prune is that it's an action (like -print), not a test (like -name). It alters the "to-do" list, but always returns true.
    1. Did you expect the temp directory to get printed? In the last example, we saw the directories ./temp and ./C/temp got printed, but not now. This is the effect of the -print option. By default, the find command prints all the files matching the criteria. However, once the -print option is specified, it will print files only on explicit print instructions. In this find command, -print is associated in the other side of the OR condition, and hence nothing will get printed from the 1st part of the condition.
    2. 12. Same using the wholename option and prune to exclude directory: $ find . -wholename "./temp" -prune -o -perm 644 -print ./area.pm ./C/temp ./C/f2.c find has a switch with the name 'wholename'. Say, in your directory tree, there might be more than one temp directory. The earlier approaches will prune all the temp dierctories. In case, if the requirement is to prune a specific temp directory, then you can give the path of the directory itself. Note: The path specified in the wholename option should be relative to the search path specified, not the absolute path.

    1. GitHub Packages uses the native package tooling commands you're already familiar with to publish and install package versions.

      Looks like GitHub Packages acts as a wrapper to these clients, acting on your behalf so you don't have to use the CLI yourself.

    1. Using find and cpio is a more unix-y approach in that you let find do the file selection with all the power that it has, and let cpio do the archiving. It is worth learning this simple use of cpio, as you find it easy to solve problems you bang your ahead against when trying tar.

    1. From the man pages The environment variables can be specified in lower case or upper case. The lower case version has precedence. http_proxy is an exception as it is only available in lower case. Using an environment variable to set the proxy has the same effect as using the --proxy option

    1. In Bash you quite often need to check to see if a variable has been set or has a value other than an empty string. This can be done using the -n or -z string comparison operators.

      Two most useful commands in bash

    1. If you have a copy of the ReSpec repository handy, you may see that there is also a respec2html.js tool under tools/. Feel free to try using it instead of the above process, but please note that it is not used much currently and may behave in a somewhat experimental manner (experiences with it vary — but it's worth a shot if you're looking for a way to generate ReSpec output from the command line).

      Respec (sadly) doesn't quite have a command line tool...at least not one comparable to a browser's output.

      Maybe PhantomJS (which Respec uses for tests) would do a better job?
