Dear Person,

I have found a bug in the below environment and using grep along with REGEX.

My aim: To search a names having "Mr.*" and "Mrs.*" in f1.dat file

$ cat /etc/*-release
Enterprise Linux Enterprise Linux Server release 5.8 (Carthage)
Oracle Linux Server release 5.8
Red Hat Enterprise Linux Server release 5.8 (Tikanga)

$ cat f1.dat
Output:
MRavi
Mr.Kumar
Mrs.Linda
Mrs.Lily
Mr.Gul
Mr.Tent
Mrs.Forrest
Mr.Hammer

$ grep -r "Mr.*" f1.dat
Output:
Mr.Kumar
Mrs.Linda
Mrs.Lily
Mr.Gul
Mr.Tent
Mrs.Forrest
Mr.Hammer

$ grep -r "Mrs.*" f1.dat
Output:
Mrs.Linda
Mrs.Lily
Mrs.Forrest

I see the command ($ grep -r "Mr.*" f1.dat) is getting retrieved all names having both Mr. and Mrs.

please do let me know is this defect ? Hoping to get an revert mail on this.
