I have always seen few interview questions from Linux and UNIX along with SQL in almost every Java programming interviews. You just can not afford not to prepare questions from UNIX and Linux until your Job absolutely doesn't require any work in UNIX operating system. I have collected many UNIX command interview questions and already shared them but I found that except system admin jobs, many programming job interviews only focus on general UNIX commands e.g. chmod, find or grep and fundamentals like finding files and directories, managing file space, networking commands, checking process status and managing file permissions. In this article we will see such kind of frequently asked interview questions and answers from UNIX and Linux operating System. Questions are very fundamental in nature and not limited to Linux only and equally applicable to other UNIX operating systems e.g. Solaris, IBM AIX etc. Many of these UNIX questions are asked during various interviews on companies like TCS, Infosys, Citibank , Wipro, Capegemini and Tech Mahindra. But as I said they are very fundamental and can be asked in any company. UNIX and Linux Interview questions answers

3. How will you find which operating system your system is running on in UNIX? By using command "uname -a" in UNIX 4. How will you run a process in background? How will you bring that into foreground and how will you kill that process? For running a process in background use "&" in command line. For bringing it back in foreground use command "fg jobid" and for getting job id you use command jobs, for killing that process find PID and use kill -9 PID command. This is indeed a good Unix Command interview questions because many of programmer not familiar with background process in UNIX. 5. How do you know if a remote host is alive or not? You can check these by using either ping or telnet command in UNIX. This question is most asked in various Unix command Interview because its most basic networking test anybody wants to do it. 6. How do you see command line history in UNIX? Very useful indeed, use history command along with grep command in UNIX to find any relevant command you have already executed. Purpose of this Unix Command Interview Questions is probably to check how familiar candidate is from available tools in UNIX operation system. 7. How do you copy file from one host to other? Many options but you can say by using "scp" command. You can also use rsync command to answer this UNIX interview question or even sftp would be ok. 8. How do you find which process is taking how much CPU? By using "top" command in UNIX, there could be multiple follow-up UNIX command interview questions based upon response of this because “TOP” command has various interactive options to sort result based upon various parameter. 9. How do you check how much space left in current drive ? By using "df" command in UNIX. For example "df -h ." will list how full your current drive is. This is part of anyone day to day activity so I think this Unix Interview question will be to check anyone who claims to working in UNIX but not really working on it.
