Code:
$ while read line; do
> if ! echo $line | grep -o "^>.*" >/dev/null; then
> echo $line | sed 's/Z//g'
> else
> echo $line
> fi
> done <infile.dat
>tempZ_1
SAFSDAFDSG
GGERRTT
ASRARARET
WETPOASDA
ASASFAS

>temp_9
ASAEGPIOEO
EIOPIAS
FDFGARA
ESEAAAS
$

Simply type ">newfile.dat" after "<infile.dat" if you want to redirect the output in a new file instead of only printing it on screen.

Edit: Looks like I missed something Smilie
