I've a string something like this: abdh0chjkj0g.
I want to delete the second last character only if it is a 0.
I know sed and awk would do the work..but i'm unable to get the exact command for this.
Any help?
awk sed

Should all zeros be removed fromrcaoe0aoea0oand allBfromaoBoaeBo? or is only the second to last character or zeros in general?

Hi, Only the 'zero' present in the second last position needs to be removed. Thanks

Using sed :
$ echo 'abdhchjkj0g' | sed 's/0(.)$/1/'
Using perl :
$ echo 'abdhchjkj0g' | perl -pe 's/0(?=.$)//'
Using gnuawk :
$ echo 'abdhchjkj0g' | awk 'print gensub(/0(.)$/, "\1", "1")'

I don't think this quite does what is asked for yet (I think because the example doesn't match the question) - you'll need to pull all0s to match the question. For example, I think,dsgf0dsfads0d0dwould need to becomedsgfdsfadsdd

And, as far as I can interpret his comment, only if it is a zero.

0s to match the question. For example, I think, dsgf0dsfads0d0d would need to become dsgfdsfadsdd– cunninghamp3
