Bash extract project name from url github

I have the following code:

url='https://github.com/Project/name-app.git'
echo $url

I have to get this back to me, i.e. the name of the project regardless of the owner of the project.

Result:

name-app

Solution

  • You can use string manipulation in Bash:

    url='https://github.com/Project/name-app.git'
url="${url##*/}" # Remove all up to and including last /
url="${url%.*}"  # Remove up to the . (including) from the right
echo "$url"
# => name-app

    See the online Bash demo.

    Another approach with awk:

    url='https://github.com/Project/name-app.git'
url=$(awk -F/ '{sub(/\..*/,"",$NF); print $NF}' <<< "$url")
echo "$url"

    See this online demo. Here, the field delimiter is set to /, the last field value is taken and all after first . is removed from it (together with the .), and that result is returned.
