Bash Scripting with function that takes an argument

Question

I need to create a function and pass an argument like

myfunc word_100

and then the output should display

word_101

Basically it should increment taking in account the delimiter. I am thinking to say put word as one variable and the number and increment the number and combine it together. But not sure how to go about.

Answer 1

Try:

NAME=${1%_*}_
NUM=${1##*_}
echo $NAME`expr $NUM + 1`
