# Replace git tags to semantic version
# e.g. v1.0.0 -> 1.0.0

for vtag in $(git tag -l | awk '$0 ~ /^v/')
do
    tag=$(echo $vtag | sed -e 's/^v//')
    git tag $tag $vtag
    git tag -d $vtag
    git push origin :refs/tags/v$tag

git push --tags

A ruby script that removes all tags with 'v' prefix (both local and remote)

tags = `git tag`.split("\n")
tags.each do |tag|
  if tag.start_with?('v')
    `git push --delete origin #{tag}`
    `git tag -d #{tag}`
  end
