Use gh cli and fzf to add a remote for a fork of the current repo

add_fork_remote.sh

#!/bin/sh

# Scenario:
# - you have a local checkout of a github repo
# - you're looking at public forks of that repo
# - you want to add a remote to your local checkout for one of the forks

set -e
set -o pipefail

# Use a fifo for a POSIX compatible array read.
FP=$(mktemp -d)/fifo
mkfifo "${FP}"

# Fetch all forks of the repo in the current directory.
# Sort by last pushed date.
# For each fork, print .pushed_at, owner.login, and .clone_url
# Use fzf to select a fork, and:
#   - don't include column 3 in the preview
#   - sort in reverse order (most recently pushed at the bottom)
# Redirect selection to the fifo; background so we don't block.
gh api --paginate "repos/{owner}/{repo}/forks" \
    | jq -s '.[] | sort_by(.pushed_at)' \
    | jq -r '.[] | "\(.pushed_at) \(.owner.login) \(.clone_url)"' \
    | fzf --with-nth=1,2 --tac > "${FP}" &
# Read the fifo and let word splitting do its thing. We only need the last two words.
read -r _ FORK_OWNER FORK_CLONE_URL < "${FP}"
git remote add "${FORK_OWNER}" "${FORK_CLONE_URL}"
echo "Added remote ${FORK_OWNER}"

For line 9, I think you mean

set -o pipefail

oh no. good catch, fixed!

Your script is definitely better, thanks for sharing :) Let me go on record to say that I re-read my script, and laughed at this part:

# Use a fifo for a POSIX compatible array read.

In closing, I will try to settle down :)
