Annotation
Don’t be afraid of command line! It is friendly and powerful tool allowing to process large data and automate tasks. Practically identical is command line also in Apple macOS, BSD and another UNIX-based systems, not only in Linux. The course is designed for total beginners as well as intermediate advanced students. The only requirement is an interest (or need) to work in command line, typically on Linux computing server.
Knowledge of Linux/UNIX is useful e.g. for working with large molecular and another data on computing cluster like MetaCentrum. It is service provided by CESNET allowing access to huge computational capacity, which is readily available for all students and employees of Czech academic institutions to process their data. You can immediately use skills learned during the course. The course contains theoretical introduction as well as plenty of practical examples and exercises.
The course will be taught 4 days, while 3 days are for teaching and last day is for exams and individual consultations. Course participants can stay this last day (which is recommended), but it is not conditional.
The course will be taught January 15-18, 2024, Benátská 2, lecture room B12, from 9:00 to 16-17:00 (with enough breaks). Depending on epidemiological situation the course can be in hybrid mode (not only in full attendance) or fully on-line only. Details will be updated according to the situation prior the course.
Consultations are possible any time after previous e-mail agreement.
