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条编码>和<代码>第2条代码>?
sed "s/$date1/$date2/g" wlacd_stat.xml >tmp.xml
mv tmp.xml wlacd_stat.xml
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

sed "s/$date1/$date2/g" wlacd_stat.xml >tmp.xml
mv tmp.xml wlacd_stat.xml
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
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。
