I joined Cognizant as a fresher somewhere around 7 months before and after being in the IT company for this long, one latest trend or craze I have seen is for UNIX. UNIX language is basically a shell language and programming in UNIX involves shell scripting. Both are difficult to understand and it takes time to get a grip on it since in UNIX you don’t get the luxury of a GUI unlike Windows, which most of us are accustomed too.
That really makes UNIX developers very rare in market and also they are the highly paid ones . Mastering UNIX is a slow and steady process. Its more of getting accustomed to it than understanding it. For this you need a lot of practice. Not many of us have the option of installing a full fledged flavour of UNIX on our machine and that makes it difficult to practice it.
