linux - How to pass parameters to a Bash script?

Question

I have a bash script as below, and I want it to read two dates as parameters, for example: myshell date1 date2. How do I assign parameters to variables date1 and date2?

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

Answer 1

You use $1, $2 in your script. E.g:

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