Shell Programming and Scripting

Hi Guys,


Can you help me with a sed or a csh script that will have an output from the input below. Cutting the columns starting from the end of the line and not from the start of the line?

Sample1 - The underscore character "_" is actually a space...i need to put it as underscore here coz the characters are right-justified and it doesn't show the correct format when i post the data here...

input:
++++
D_1_
T_6_
1_5_
_19_
_23_
_30_
_37_
_65_
105_
201_

output:
+++++
1
6
5
19
23
30
37
65
105
201


Sample2 - Same as sample 1 only truncate the space from Sample1 and change to comma then cut and get the data with reference to the last comma in the line:

input:
++++
D,1,
T,6,
,19,
,23,
,30,
,37,
,65,
105,
201,

output:
+++++
1
6
19
23
30
37
65
105
201


Let me know...Thanks a lot for your time guys!

echo "1_2_233_33" | awk -F"_" '{x=NF-1 ;print $x}'
233

Hi demwz...that was quick...i used your code for the csv sample2 and works like a charm ---> awk -F"," '{x=NF-1 ;print $x}'

thanks!
