Hi,
Does anyone know how many ways to pick out last charactor of a string?

Thanks!

What shell?

I am using ksh for this program.
But I'd also like to know if there is more than one way to do it.
Even maybe using awk, sed, perl....

Thanks a lot!

Code:

#!/bin/ksh

a='123'
echo "${a#${a%?}}"

# OR
echo "${a}" | sed 's/.*\(.\)/\1/' 

# OR
echo "${a}"  | nawk '{print substr($0, length($0))}'

Or...

Code:

expr "${a}" : '.*\(.\)'

- or....

Code:

echo "${a}" | tail -2c

BTW - it's -2c as there's a trailing newline too.....

Cheers
