AWK Help

[inderPunj]

Hi All,

I want to create a script in which i want to fulfill three conditions with awk command.
I want to search from a sentence if there is sel at the end of string, then it append "_aa01", if it has del at end it will append "_bb01", if nothing between both conditions it will append "$DATE"

if i can satisfy these all three conditions without awk, please let me know with examples.

Please help.

Thanks,
Inder Punj

Please post sample input and an example of the desired output.

The 3 comdition should be as follows :-
1. Let i have inder_eatapple_sel then it will append _aa01 at the end, LIKE - inder_eatapple_sel_aa01
2. If i have inder_eatapple_del then it will append _bb01 at the end LIKE - inder_eatapple_del_bb01
3. if it has not sel nor del at the end, then it append current date.

Please suggest, if want more clearification , please let me know.

Thanks,
Inder

Yes,
as I said, post sample from the input and example (not description) of the desired output.

Seems a pretty clear statement of the requirement to me.

awk '
/_sel$/  {print $0 "_aa01"; next}
/_del$/  {print $0 "_bb01"; next}
             {print $0 "_'$(date +%Y%m%d)'"}' inputfile

Adjust the date command to give the format you require (but avoid including slash characters (/)!).

[radoulov]

This should be sufficient:

awk '
$0=$0"_"(/[sd]el$/?(/_sel$/?"aa":"bb")"01":d)
' d="$(date +%F)" file

Avoid calling the external date command for every matching record ...

I prefer to have an example in/output though ...
