Linux Basics
Depending on your requirement, you can have a look at one (or more) of the following documents: [Top] [Editors] [Encryption] |
Editors
It is quite possible that you will spend more time using an editor than any other application--for programming, for LaTeXing, for writing web pages, and so on. For Linux/Unix environment, best editor without doubt is XEmacs. It is installed in all the Linux machines in our computer centre (cc15 and cc10). There is a Windows version of XEmacs also. XEmacs is h-u-g-e in size for a text editor; but thats because it has about 3 mail readers, one web browser, and several games among other things, built in! It is totally customizable, and easily much more powerful than any other text editor you would have seen. You can make xemacs download your pop mails and read/reply/compose mails, just like the netscape mailer or the microsoft outlook express. In the Windows environment, you might try NoteTab Light, which is a freeware, or WinEdt (there is no `i'!), which is a shareware. Both these editors work well with the MikTeX distribution, which is what we would advocate as the TeX environment for Windows systems.
A Bit More on XEmacsIf you are working in a Linux machine, and have XEmacs installed there (all the Linux machines in the computer centre have it), then all you have to do is to download the file myxemacs.tar.gz in your home directory, then type the following at the shell prompt:tar zxvf myxemacs.tar.gz Now you are ready to go! Just type xemacs & at the shell prompt, or click on the xemacs icon in the start menu if you are using any of the computer centre linux machines. [Top] [Encryption] |
GPG (Gnu Privacy Guard) (For the latest versions of the following softwares, you should visit the page www.gnupg.org)
"Gnu Privacy Guard"--a free equivalent of PGP ("Pretty Good Privacy"). gpg is more secure than PGP and does not use any patented algorithms. gpg is mostly used for signing your e-mail messages and checking signatures of others. You can also encrypt/decrypt messages. http://www.gnupg.org/ contains all the details, including a legible, detailed manual. To start, I needed a pair of keys: private and public. The private key is used for signing my messages. The public key I give away so that other can use it to verify my signatures. [One can also use a public key to encrypt message so it can only be read using the private key.] I generated my keypair using this command:[ Top] |
