It includes everything needed to run the wicd daemon and the wicd-cli and wicd-curses interfaces. To enable visual notifications about network status, you need to install the packages notification-daemon and python2-notify AUR. First, stop all previously running network daemons like netctl, netcfg, dhcpcd, NetworkManager. Disable any existing network management services, including netctl , netcfg , dhcpcd , and networkmanager.
Refer to Systemd Using units. If you have installed the wicd-gtk-git AUR and entered the desktop environment. Open a virtual terminal to run one of the following commands. If you did not install wicd-gtk-git AUR then use wicd-cli or wicd-curses:.
If wicd-curses is failing for some reason you can connect using wicd-cli. Wireless example sudo may be required :. Wicd still suggests to "almost always" use Wext as WPA supplicant driver and defaults to it.
This is outdated behavior. One should use nl instead, except with old drivers that do not support it. If so, enable the wicd systemd unit. Simply change the values within the case statement to match those of the networks you want to set static ARP entries for. Is there a better way than simply trying to open the file?

Or do you want to check, and write to the file if it doesn't already exist. If so, see my answer below, for a version that doesn't suffer from race conditions. Of course, both stat and access rely on being able to access the directory containing the file; all bets are off if you can't do that no execute permission on the directory containing the file. Joakim is solving the symptoms, not the problem. Just separate it into to lines; an extra line won't hurt that much.

C is another ISO standard; it does not. There are pitfalls associated with access. There is a TOCTOU time of check, time of use window of vulnerability between using access and whatever else you do afterwards.
This only matters to setuid or setgid programs, but then it matters intensely as it may give the 'wrong' answer. If the tested file is in a directory that the real UID or real GID cannot access, access might report no such file when it does exist.
Esoteric and improbable? Show 17 more comments. Adam Liss LudvigANorin: on such systems, the chances are that access also has problems, and there are options to use to make access and stat work with large files bigger than 2 GB. Could either of you point to documentation regarding the failure after 2 GB? Also, what is the alternative in such cases? It's not clear to me that it would be better.
It depends what you're going to do based on the presence or absence of the file. Using the correct options to open is usually the best way of dealing with the problems, but it can be tricky formulating the right options. This way even if file does not exists anymore at TOU, you still can access it through file-descriptor. Its content will be kept as long as there are processes that have it opened.
