This is my sample file
cat bipin.txt
Unix is an OS
Unix has its own commmands
Unix is a user friendly OS
Unix is platform independent
Unix is a time sharing OS
the best OS to learn is Unix
Abinitio uses Unix in backend
When i use sed 's/Unix/Linux/' bipin.txt
, only the first occurrence of Unix
must be replaced with Linux
right ??
But for me all the occurences are getting replaced .
Could someone please tell me where am making a mistake , please help me
