I want to know, how can we check in the bashrc file, what operating system is it?

Use uname -a in your .bashrc file.

There is no portable way to know what Operating System is running.

Depending on the OS, uname -s will tell you what kernel you are running but not necessarily what OS.

Moreover, it cannot be SunOS or Unix or Solaris. Solaris is all of them: both a Unix compliant OS and an OS based on the SunOS kernel.

One of these might give you a precise answer depending on the Unix or Linux implementation:

cat /etc/release # SVR4, Solaris
cat /etc/redhat-release
cat /etc/*elease
cat /etc/lsb-release
oslevel -r # AIX
system_profiler -detailLevel -2 # Mac OS/X

Try this: 

$cat /etc/os-release
NAME="Ubuntu"
VERSION="12.04.4 LTS, Precise Pangolin"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu precise (12.04.4 LTS)"
VERSION_ID="12.04"
  • And what's that supposed to do? Basile's answer seems to cover this question just fine, so please explain what this code improves compared to Basile's. – Joeytje50 May 13 '14 at 00:16
  • LOL.. whatever.. it's not code btw.. just a more specific answer to a question. –  May 15 '14 at 21:45
  • :) Thanks user.. +1 for the precise answer.. though.. I just wanted the OS name, which was answered earlier by Basile, and it fitted my needs. Also the answer by jlliagre gave me these information as well. – Kumar Alok May 20 '14 at 06:30
