A few more shell commands
8th July 2015Here are some Linux commands that I encountered in a feature article in the current issue of Linux User & Developer that I had not met before:
cd -
This returns you to the previous directory where you were before with having to go back through the folder hierarchy to get there and is handy if you are jumping around a file system and any other means is far from speedy.
lsb_release -a
It can be useful to uncover what version of a distro you have from the command line and the above works for distros as diverse as Linux Mint, Debian, Fedora (it automatically installs in Fedora 22 if it is not installed already, a more advanced approach than showing you the command like in Linux Mint or Ubuntu), openSUSE and Manjaro. These days, the version may not change too often, but it still is good to uncover what you have.
yum install fedora-upgrade
This one can be run either with sudo or in a root session started with su and it is specific to Fedora. The command performs an upgrade of the Fedora distro itself, and I wonder if the functionality has been ported to the dnf command that has taken over from yum. My experiences with that in Fedora 22 so far suggest that it should be the case, though I need to check that further with the VirtualBox VM that I have created.
Adding Microsoft Core Fonts to Fedora 19
6th July 2013While I have a previous posting from 2009 that discusses adding Microsoft's Core Fonts to the then current version of Fedora, it did strike me that I hadn't laid out the series of commands that were used. Instead, I referred to an external and unofficial Fedora FAQ. That's still there, yet I also felt that I was leaving things a little to chance, given how websites can disappear quite suddenly.
Even after next to four years, it still amazes me that you cannot install Microsoft's Core Fonts in Fedora as you would on Ubuntu, Linux Mint or even Debian. Therefore, the following series of steps is as necessary now as it was then.
The first step is to add in a number of precursor applications such as wget for command line file downloading from websites, cabextract for extracting the contents of Windows CAB files, rpmbuild for creating RPM installers and utilities for the XFS file system that chkfontpath needs:
sudo yum -y install rpm-build cabextract ttmkfdir wget xfs
Here, I have gone with terminal commands that use sudo, but you could become the superuser (root) for all of this and there are those who believe you should. The -y switch tells yum to go ahead with prompting you for permission before it does any installations. The next step is to download the Microsoft fonts package with wget:
sudo wget http://corefonts.sourceforge.net/msttcorefonts-2.0-1.spec
Once that is done, you need to install the chkfontpath package because the RPM for the fonts cannot be built without it:
sudo rpm -ivh http://dl.atrpms.net/all/chkfontpath
Once that is in place, you are ready to create the RPM file using this command:
sudo rpmbuild -ba msttcorefonts-2.0-1.spec
After the RPM has been created, it is time to install it:
sudo yum install --nogpgcheck ~/rpmbuild/RPMS/noarch/msttcorefonts-2.0-1.noarch.rpm
When installation has completed, the process is done. Because I used sudo, all of this happened in my own home area, so there was a need for some housekeeping afterwards. If you did it by becoming the root user, then the files would be there instead, and that's the scenario in the online FAQ.
Adding msttcorefonts to Fedora
28th July 2009Once you have enabled the appropriate software repository, you can install the msttcorefonts (Microsoft TrueType core fonts like Arial, Times Roman, Verdana, Georgia, etc.) package on Debian and Ubuntu. With Fedora, it surprisingly isn't so straightforward. There is a recipe using the command line that worked for me, and I'm not going to repeat it here, so I'll leave you to go where I found it. In fact, it forms part of a wider unofficial Fedora FAQ that may be of more interest to you than solving this.
Update for Fedora 12 (2009-11-24):
You also need chkfontpath so the following needs doing before the final part of the command sequence, changing the filename as appropriate for your situation:
yum install xfs
rpm -ivh http://dl.atrpms.net/all/chkfontpath-1.10.1-2.fc12.i686.rpm
A UNIX shell running on Windows
15th November 2007Here's an idea that I got for a post before I spent that torrid weekend with Windows that caused me to jump ship to Linux. The idea of having a UNIX command line while still remaining on Windows did appeal to me at the time, and Cygwin seems to provide an intriguing way to do this. At its most basic, it is a set of DLL's that allow you to run standard UNIX commands in a shell like what you see below. However, it is extensible with a good number of packages that you can choose to install. NEdit is just one that gets included, and I think that I spied Apache too. The standard installation is a web-based affair, with your downloading only the components that you need; it's worth trawling through the possibilities while you're at it.
Now that I am firmly ensconced in the world of Linux, this may be one possibility that I will park, for a while anyway. After all, I now do have the full power of the UNIX command line...
