How to get particular word from string in bash

Example strings:

app:mob-type1-subtype:1.0.2
app:mob-type2:1.0.1

Above are my example strings, I want to fetch "type" value from above string.

How can I do it using bash script?

I have tried the following

Code:-

res="${element#*-}"
echo $res| awk -F : '{ print $1 }'

Result (Incorrect one)

type1
type2-subtype

But I want to get type1 and type2 values only not subtypes. How can I do it in a better way?

Here is a solution, considering your text is in a.txt

cat a.txt | grep -Eo "type[0-9]+"

It will give the output as below:

type1

type2

cat file

app:mob-type1-subtype:1.0.2
app:mob-type2:1.0.1

Using awk you can do:

awk -F '[:-]' '{print $3}' file


type1
type2

Here is one bash solution if you're have input in a shell variable:

IFS='[:-]' read -ra arr <<< 'app:mob-type1-subtype:1.0.2'
echo "${arr[2]}"


type1
