Question

I wrote a shell script like this:

#! /bin/sh
...
ls | grep "android"
...

and the output is :

android1 
android2
xx_android
...

I want to add a number in each file, like this:

    1 android1 
    2 android2
    3 XX_android
    ...
    please choose your dir number:

and then wait for the user input line number x, the script reads the line number back then process the corresponding dir. How can we do this in shell ? Thanks !

Instead of implementing the interaction, you can use built-in command select.

select d in $(find . -type d -name '*android*'); do
    if [ -n "$d" ]; then
        # put your command here
        echo "$d selected"
    fi
done
