• 如何将参数带至双字母?
原标题:How to pass parameters to a Bash script?

我有下文的印本,我希望将其改为两个日期作为参数,例如:myshelldate1date2。 我如何将参数分配给<代码>第1条和<代码>第2条?

sed "s/$date1/$date2/g" wlacd_stat.xml >tmp.xml
mv tmp.xml wlacd_stat.xml
最佳回答

请在您的书中使用<1>,$2。 例如:

date1="$1"
date2="$2"
sed "s/$date1/$date2/g" wlacd_stat.xml >temp.xml
mv temp.xml wlacd_stat.xml
问题回答

为了加速参数,你可以使用这一短手:

#!/bin/bash
for a
do
    echo $a
done

该表与“美元”/代码中的<代码>相同。

Bash的论点是在其立场之后提出的。

此外,如果你需要处理另一个论点,你可以改变这些论点,并总是使用<1<0>1>代码>:

while [ $# -gt 0 ]
do
    echo $1
    shift
done
$0
$1
$2

因此,将包含文字名称,然后是第一线和第二线论点。
