Download Episode 23
Hi, I am back!! This week I talk a little bit about root and sudo and how that is used in Ubuntu. Just a couple of things about it, firstly, that the root account and hence the ability to use a root terminal is turned off by default. You can however turn this feature on at your leisure, though not recommended. In any case, root as you may have heard on the podcast is like an administrator account in Windows. This account can do just about everything to your computer that you would want it to do and some things that you might not want it to do. Again, it is powerful, but, alas not idiot-proof. This is where sudo comes in. Sudo is a command line command that begs for a little more attention than the usual command line command of the week. What sudo does is allows the user with your regular run of the mill permissions to do administrative tasks. Things like edit configuration files, setup file permissions, and download..um...packages, yes, to install on your system. The way I see it as explained in the podcast root is to sudo as Superman is to Clark Kent. Either way, both have the same weaknesses and that is kryptonite, or incorrect command line input. See, Superman isn't so BAD after all. For the regular user, you might never have to access a root account. I'll be honest with you I haven't even tried. But, one never knows when I have to rip off my button down shirt to reveal my Superman footie pajamas (don't be jealous, I got them for Christmas!) Well, there you go, just a couple things about root and sudo and pajamas, hmmm. Here is a link to more informatioin about root and sudo:
This weeks CLCOTW: wc - Counts word (among other things, check the man pages) in various files.
Pretty handy to have around if you are the obsessive/compulsive type that has to know how many word you type...97..98..99...excuse me. You can also find out how many characters and bytes if you want. From the screenshot, I wrote 1721 words in my preparation for this episode, wow, not bad!! I hope this helps someone!!!
ere is a great tip from Steve B., he recommends a package called Yakuake for all you command line geeks. I downloaded it and it does run on gnome as well as kde. Knock yourself out. See screenshot below.
See you all next week!!
