循环时限制bash到10次重试

这个while循环如何限制为最多10次重试？

#!/bin/sh
while ! test -d /somemount/share/folder
do
    echo "Waiting for mount /somemount/share/folder..."
    sleep 1
done

保持柜台：

#!/bin/sh

while ! test -d /somemount/share/folder
do
    echo "Waiting for mount /somemount/share/folder..."
    ((c++)) && ((c==10)) && break
    sleep 1
done
