For SSH agent forwarding in Termux, you can try the following steps:
Start the SSH agent by running: eval $(ssh-agent)
Add your SSH private key to the agent using: ssh-add /path/to/your/private_key
Check if your SSH agent is running and has your key by using: ssh-add -l
If you encounter the passphrase prompt, enter your passphrase to add the key to the agent.
Now, simply use git pull or git push commands as usual. The SSH agent should manage authentication without repeatedly asking for the passphrase.
