惠普尔尾巴以命令的形式检测连字符。

Question

我试图使用whiptail做一个检查表，但是当我输入其中一个选项时，它会检测到它是一个命令，尽管它是用引号表示的。这个清单的要点是对文件进行bash处理，并在bash期间将变量添加到shell命令的末尾，即

bash something.sh -cached_var_here

下面是代码和错误：

BENCH=$(whiptail --title "Choose Benchmark Options" --checklist "Choose:" 20 
30 15 \
 "-info" "System Information" off \
 "-io" "System I/O Test" off \
 "-cdn" "CDN Test Download (200MB)" off \
 "-northamerica" "North-American Server Test Download (800MB)" off \
 "-europe" "European Server Test Download (900MB)" off \
 "-asia" "Asian Server Test Download (400MB)" off \
 "-b" "System Information, CDN Download Test & I/O Test" off \
 "-speed" "Network Speedtest Using speedtest-cli" off \
 "-share" "Share Your Results With Others!" off \
 "-help" "Help Menu. Do NOT Execute This With Other Options!" off \
 "-about" "Show About-Info. Do NOT Execute This With Other Options!" off \
3>&1 1>&2 2>&3)

echo "You chose the following options: $BENCH"
echo

echo "Do you want to run CUSTOM benchmark and information? (y/n)? "
old_stty_cfg=$(stty -g)
stty raw -echo
answer=$( while ! head -c 1 | grep -i '[ny]' ;do true ;done )
stty $old_stty_cfg
if echo "$answer" | grep -iq "^y" ;then
  echo Yes;

  curl -LsO raw.githubusercontent.com/sayem314/serverreviewbenchmark/master/bench.sh; chmod +x bench.sh
  echo
  ./bench.sh $BENCH

我知道这个错误：

You chose the following options: -info: unknown option

让我们参考man whiptail：

whiptail将以虚线"-“开头的参数解释为参数。为了避免这种情况，并在例如菜单框项目中使用破折号开始一些文本，whiptail遵守接受特殊参数"--“的getopt约定，这意味着下面所有带有破折号的参数都将被逐字处理，而不是被解析为选项。

因此，以下方法应该像魅力一样发挥作用：

whiptail --title "Choose Benchmark Options" --checklist -- Choose: 20 30 15 -info "System Information" off
