last position 1

[Yarka]

Hi,
How can I delete the last position of the a column efficiently?
For example, if my input is:
12350 a
2361 bc
655594 h
...

my output should be as:

1235 a
236 bc
65559 h

Thanks.

sed 's!. ! !' input > output

If the column separator is a tabulation, replace each space with a tab char.

Hope This Helps, PH.

Hi,
My sed command, don't have option s.
When I execute sed 's!. ! !' input > output, I've:
sed: -e expression #1, char 6: unknown option to `s'

Thanks.

How can I delete it in this situation?
