Question

From textfile database format,

Customer:HDB:Price:Left:Available

Ted:rm4:34:197:101

bash shell script,

read -p $'Price: '  Price2
sed -i "s/$Customer:$HDB:$Price/$Customer:$HDB:$Price2/g" CustomerDB.txt

When I key in 43, database return

Ted:rm4:4334:197:101

How do i replace it to be 43 instead of 34?

Answer 1

Seems like $Price is empty. Are you sure it contains the old price? If you want to replace all the prices regardless of the old value, you can use

sed -i "s/$Customer:$HDB:[0-9]*/$Customer:$HDB:$Price2/g" CustomerDB.txt
