Command not find showing error

In our Data Center last two day before I was facings problem on new REDHAT 6.5 linux VM machine,
When we use some basic commands it was showing command not find,
That time we were not able find  anything on this issue because of work load,
So pls help us for resolving this issue ...
Now same issue we facing on new installed  Redhat VM

I guess most probably you should share which commands you are executing and  also ensure that  by command "which"  for Path whether it exist in /bin  /sbin  /usr/bin  /usr/sbin
