我只是想知道是否可以在 for 循环中使用变量？我试过了：
for number in { eval echo {0..$1}}
do
echo 5
done
我的意思是让它打印出我输入提示的次数 5 但是，如果我输入，它的行为会很奇怪：
./test.sh 2
它应该打印 5 两次，但它会打印 5 四次。有人可以帮我弄这个吗？还有为什么它打印了 4 次而不是 2 次？
编辑：大部分
for number in $(seq "$2")
有效，但如果我尝试用它进行计算，它会破坏我的代码：
time=1
total=5
for number in $(seq "$2")
do
echo "$time + $total" | bc
done
给出：seq：无效的浮点参数：'' 尝试'seq --help'以获取更多信息。有人可以告诉我如何解决吗？
我只是想知道如何使用 sed 提取特定列？（我的系统已经安装了 sed，所以不幸的是没有 awk :(）。我得到了一个如下文本文件：

文件中有很多行还有更多行，但我猜这已经足够了。现在我需要提取 Business Name 列中的信息。所以我尝试了：
sed -n '^[^,]*,{1}p' $1
其中 $1 是从用户输入读取的文件名。我也试过：
sed -n '\^\[\^,\]*,{1}p' $1
我更熟悉 grep RE，这就是为什么它们看起来像 grep RE 而不是 sed 的原因。最近才开始使用 sed。

现在我需要使用 grep，如果解决方案不涉及 sed、perl、awk 或循环，我会更喜欢。我试过了：
grep -E "^.*(,.*){9}[^0]+" BC_Liquor_Store_Product_Price_List.csv
但这显然得到了一切。我需要获取所有具有 PRODUCT_LITRES_PER_CONTAINER >= 1 的行，但我无法弄清楚如何。.* 得到一切，但在 之前，有一些词，所以我不能这样做：

我想根据 District code 对整个文件进行排序，然后打印出结果，我只是在这里复制了几行，因为文件有 1000 多行所以。我尝试了几个命令：
cat $1 | sort -n -k 2
cat $1 | sort -t \" -n -k 2
但它似乎什么都不做？
还有一些行未排序，例如：
