Is CentOS…dead? CentOS is a Linux distribution that provides a free and open-source community-supported computing platform, functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). In December 2020, Red Hat unilaterally terminated CentOS development. In response, CentOS founder, Gregory Kurtzer, created the Rocky Linux project as a successor to the original mission of CentOS. Rocky Linux Rocky Linux is a Linux distribution that is intended to be a downstream, complete binary-compatible release using the Red Hat Enterprise Linux (RHEL) operating system source code.
Task report In the life of every system manager, sooner or later it has happened to do reporting, or by collecting data from logs, databases as diverse as LDAP servers. The thing you will surely have done is to collect data manually, using tools like grep and awk for configuration files and logs. $ cat example.log | grep 'ERROR' $ awk '{print $2}' example.log Or a bash script that analyzes each row and then selects only those of interest.
Fun terminal tools There are very useful command line tools, which are used for daily administration, whatever the job you have to do, an example are find, grep, cat, less, etc. There are also more complex tools that require the study and consultation of manuals such as docker, vagrant, etc. and are for advanced users such as systems engineers and developers. Other tools are used … well, practically nothing, except to elicit a laugh.
In the life of a designer or font maker, the need arises to see how a font looks on a certain image, with a certain color and size, or simply, have a reliable preview of the final result. To do this, graphical tools are required. Preview of a font To work with font previews, there are system previewers at the level of any operating system. This is a great starter tool to see what a font will look like on our project.
