I have been going through teh tutorials & they are very helpful thansk a lot!
However , I tried two slightly different statements on the same string & the o/p varied drastically , it is due to the position of "." in the statement .
e.x.1
Code:
echo "ABCDEFGHIJ20100909.txt" | sed -n -e 's/\(..\)\(...\).*\([0-9]\{8\}\).*/\1,\2,\3,&/p'
o/p : AB,CDE,20100909,ABCDEFGHIJ20100909.txt --> as desired
e.x.2
Code:
echo "ABCDEFGHIJ20100909.txt" | sed -n -e 's/\(..\)\(...\)*\([0-9]\{8\}\).*/\1,\2,\3,&/p'
o/p : ABCD,HIJ,20100909,CDEFGHIJ20100909.txt
Can anybody explain how the position of "." dot affects the result ?
thanks in advance .
