maybe someone can write most important things what web developer should know about linux? When I am reading linux tutorials, I often find out that I don't need this what I read. At least never needed. So its not fun to read about things which you don't need.
What I have tried/read so far is:
what is the dedault logs directory
how to delete older than X days logs
how to restart apache
how to filter processes running
currently trying out compiling a program (but as I read in Ubuntu tutorial - this is rarely needed in reality, becauseo on Ubuntu most of stuff is already compiled. If not compiled, the progrma might be not stable yet or something like that.)
writing Cron tasks
list of files
free disk space
So what is missing from this list? What should I be familiar with else?
