Is there any reason for NOT using sed or awk?
Its because I don't know awk and sed Smilie

Thank you Srinishoo

Question1.
In your solution
Code:
awk '$5 ~ /G/'

, what is the role of tilde (~) character and /G/ ?


Question2
.
How did you manage to ignore the varying spaces between the fields ?

ie. If you Subtitute space with red underscores for readability as shown below, you can see 4 underscores between user and group
and 1 underscore between group and size field

Code:
-rw-r----- 1 oracle____asmadmin_1.7G Mar 17
