我有一个正在读取用户输入的脚本。这是我的代码:
if [ -z $volreadexists ]; then
echo -e "\tThis will overwrite the entire volume (/dev/vg01/$myhost)...are you sure?"
read REPLY
echo
if [[ $REPLY =~ ^[Yy]$ ]]; then
echo -e "\t\tContinuing"
syncvolume
else
echo "Fine...skipping"
fi
fi

我必须使用,read REPLY因为read它本身不插入选项卡。我正在寻找类似的东西:
read -p "\tDoes this look OK? (n for No)" -n 1 -r

\t在阅读提示上按 Tab 键。
如何向阅读提示添加选项卡?
更新:感谢@gniourf 的精彩回答!:
read -p $'\tDoes this look OK? (n for No)' -n 1 -r

然而,我发现了一个问题。当我尝试在那里使用变量时,它不会翻译它:
read -p $'\tThis will overwrite the entire volume (/dev/vg01/$myhost)...are you sure? ' -n 1 -r

变成
This will overwrite the entire volume (/dev/vg01/$myhost)...are you sure?

我想要的地方:
This will overwrite the entire volume (/dev/vg01/server1)...are you sure?

使用双引号也不起作用:(
有任何想法吗?
我最终参考了这个答案:
并创建了一个解决方法。它并不完美,但它有效:
myhost="server1"
if [ -z $volreadexists ]; then
read -e -i "$myhost" -p $'\tJust checking if it\'s OK to overwrite volume at /dev/vg01/'
echo
if [[ $REPLY =~ ^$myhost[Yy]$ ]]; then
echo -e "\t\tContinuing"
else
echo "Fine...skipping"
fi
