# Get names with `gh repo list orgname`

For a long list of repositories, one can replace L7-L12 with

# Get names with `gh repo list orgname`
gh repo list $ORG --limit 1000 --json name --json owner -q '.[] | "\(.owner.login)/\(.name)"' | while read -r REPO; do
  echo "Adding repo ${REPO} to Org:$ORG Team:$TEAM_SLUG"

Note the --limit 1000 as well.
