如何在bash中检查字符串中的最后一个字符？

Question

我需要确保字符串中的最后一个字符是a /

x="test.com/"

if [[ $x =~ //$/ ]] ; then
        x=$x"extention"
else
        x=$x"/extention"
fi

此刻,虚假总是火上浇油.

像这样,例如:

$ x="test.com/"
$ [[ "$x" == */ ]] && echo "yes"
yes

$ x="test.com"
$ [[ "$x" == */ ]] && echo "yes"
$ 

$ x="test.c/om"
$ [[ "$x" == */ ]] && echo "yes"
$ 

$ x="test.c/om/"
$ [[ "$x" == */ ]] && echo "yes"
yes

$ x="test.c//om/"
$ [[ "$x" == */ ]] && echo "yes"
yes
