how to display only last character of a string?

hi all,
if i do an:
"echo $string |" what should be after the pipe to display ONLY the last char of the output?

Depends on your shell:

[zsh]

zsh-4.3.4% print ${${:-string}[-1]}
g

otherwise:

echo string|{ read; echo "${REPLY#${REPLY%?}}";}

thnx! works perfectly fine...

using sed

 echo $string | sed -e 's/\(^.*\)\(.$\)/\2/'

thnx also...

1 saved substring suffice:

sed '/.*\(.$\)/\1/'

With awk:

awk '{print substr($0,length,1)}'

Regards

GNU Awk:

$ echo string|awk '$0=$NF' FS=
g

# printf $s | cut -c`printf $s | wc -c`

Or:

cut -c ${#s} <<<"$s"

or with ksh93 and bash:

$ echo ${s: -1}
g

print "${string[${#string}]}"
