![]() GDebi will provide a description of the package, what files are included, and other details about the package. At the top of the context menu, you should see an option to open the package with the GDebi package installer. In that case, download the application’s Debian package (.deb) and right-click on the file. What if you want to install something like Opera that is available as a package for Ubuntu, but isn’t in the repositories? Most of the application software you’ll want to add to your system will be available through the Ubuntu repositories using Synaptic, Adept, or another package management tool. Note that on my system, I don’t have Emacs or many other editors installed if I did, the utility would offer the other editors as choices. ![]() Selection Alternative - 1 /usr/bin/vimt 2 /bin/ed * 3 /bin/nano Press enter to keep the default, or type selection number: There are 3 alternatives which provide `editor'. To change the default editor, run sudo update-alternatives –config editor. Look under the /etc/alternatives directory to see what programs are managed. The easy way to change this is to use the update-alternatives program, which maintains the symbolic links under /etc/alternatives that determine the default programs for FTP, system editor, rsh, Telnet, window manager, and so forth. For example, the default editor is set to Nano, which isn’t optimal if you’re used to Vim. Ubuntu comes with a number of defaults that may or may not be to your liking. However, if you run Ubuntu on AMD64 or PowerPC hardware, you’ll still be out in the cold for some of the packages, since some multimedia formats depend on proprietary software that’s not available for those hardware platforms. The Ubuntu wiki has a page on restricted formats that explains how to get the packages you need. This is inconvenient, but the Ubuntu folks have good reasons for not shipping with support for MP3, DVDs, and so forth - including that software could cause them some legal headaches, or incur some serious fees.įortunately, as a user, you don’t need to worry about fees (though some of the packages may not be legal due to patent restrictions or restrictions on circumventing copy protection, depending on where you live). If in doubt, create a longer password, or pass your generated password as input to another generator, or use multi-factor authentication.The default Ubuntu install contains free software only, which means that it doesn’t support some popular multimedia formats straight out of the box. And it's certainly better than using 'Pa$$w0rD' for everything. You probably know when this is useful or not. Have bad vision, but in general use of this option is not recom‐ Number of possible passwords significantly, and as such reduces Printed, such as 'l' and '1', or '0' or 'O'. Stil, pwgen put gives this caveat in its man page, describing its -B option: -B, -ambiguousĭon't use characters that could be confused by the user when You would want to use an option like this if you are resetting someone's password or giving a one-time passkey that needs to be communicated. However, you will at some point probably appreciate applications (like pwgen, KeePassX or LastPass) that give you an option to avoid easily confusable characters, like 1 and l and I. the sed expression strips out strips out spaces and tabs (represented by \s). To get a larger selection, pass more bytes to head, and to get longer password result strings, modify -bytes in strings (which gives a minimum length). I suspect your use case if different, but this kind of thing is useful for shared secret keys, and other kinds of passwords that you don't type in very often. The results are more hideous even than apg or pwgen (even with the -s option set), but this is more fun: head -c 8192 /dev/urandom | strings -bytes 8 | sed 's/\s//'
