Our company develops a lot of complex and multicomponent products, and we have to constantly read and analyze a huge number of logs, while from some multi-gigabyte files we need to get only a small part of the information. Each QA used tools that were convenient for it, and when switching to a project with a different operating system, it had to look for and learn new tools. We also had to maintain our own Wiki system for each project to train new team members. Therefore, in order to optimize processes, it was decided to standardize the system for working with logs to select the most versatile and accessible tools. As a result, the choice fell on simple tools for Linux Shell, which can be used in various operating systems. As a result, a General guide was compiled for opening and analyzing logs for the main operating systems using the selected tools and this speeds up the entry of new team members in a project.
