I came across a very useful post with the listing of many shell keyboard shortcuts. The article covers a mix of bash, csh, zsh, and Cisco shell keyboard shortcuts. The article is in Russian, but I think it will be helpful for more people, so I took the liberty to translate it. Continue reading for the translation.

Once in a while there is a need to see the tree of processes on a Linux system. When such a need arises, I usually run “ps auxw –forest“, which results in something like this (partial output, top only):
Today, via this blog post, I’ve learned that there is another way – “pstree“. This command accepts a number of parameters, but in its simplest form, results in something like this (partial output, top only):
On my Fedora box, /usr/bin/pstree is a part of the psmisc RPM, which is the one that brings /usr/bin/killall to the system.
I was quite surprised today how well the standard HTML (non-JavaScript) version of Gmail works in console browser links. Everything is there – folders, labels, messages in inbox, search, and even compose. I don’t think that too many people are actually using this version, but kudos to Google for still supporting it – in those desperate times, when nothing else works, it’s nice to have at least this front covered.
I don’t know how I missed the announcement and why there is no noise around this release, but here it goes. GoogleCL is a tool that you use from the command line to access Google web services. I just installed it on my Fedora 13 laptop and its awesome!
Here is what you need to do to intall
$ sudo yum install python-gdata $ wget http://googlecl.googlecode.com/files/googlecl-0.9.7.tar.gz $ tar xzvf googlecl-0.9.7.tar.gz $ cd googlecl-0.9.7 $ sudo python setup.py install
Here are some of the things that you can do. And I guess more is coming shortly.
The first time you’ll connect to any of the Google web services using this tool, you’ll need to authenticate and grant access to the application. After that – it’s all pure honey.
Those of us who use secure shell (SSH) for logging in to remote machines, already know about key authentication, which is so much easier and sometimes more secure than password authentication. We also know that in order to make it work you need to:
And that’s just what we have been doing. Or at least me. Today, after approximately 10 years of using secure shell, I’ve learned that there is a ssh-copy-id command, which will automatically add your current public key to a remote machine’s authorized_keys file and arrange for correct permissions. Wow!
