Useful Git scripts

These git bash utility scripts will:

execute add and commit git operations on a specific date rather than the current time/date right now
change the Author & Commiter Name and Email for all commits in a workdir
update the Author & Commiter Name currently in use in gitconfig

	### This gist is a set of notes from this blog post: https://sureshjoshi.com/development/raspberry-pi-wifi-to-ethernet-bridge

	### NOTE: This is not a ruanable script - it is strictly a breakdown of the snippets from the blog article, not an automated script.
	### For automation, refer to the Ansible role

	### Some sets of commands below have been added to allow specific blocks to be copied and run at the command-line

	echo "### This script wgets the logexec.sh script & makes it eexcutable, runs apt/yum/dnf update & upgrade, gets .screenrc and does other setup tasks ###"

	# rclone-db-bkup-to-s3.sh
	# [2018Nov30 mkartha] transfer backups from the /mnt/nas/BackupLinux/ Db pg dumps to S3 using rclone
	# - do this as root from the db-server or a server with rclone in PATH and access to db dumpfiles
	# - this script also assumes that rclone has been configured with S3 credentials to transfer data to S3 with rclone profile aws-s3

	# skeleton example
	#restore_scripts/mkartha/logexec.sh rclone sync ./2018-11-28-daily aws-s3:db-backup/db-backups/2018-11-28-daily/ --ignore-checksum --fast-list --verbose

	# usage: run script from the /mnt/nas/BackupLinux/ directory on a db server, with the 1st parameter as the name of the backup directory to transfer to S3

	# [2016Dec26 MCK] - logexec.sh - this script runs the given command, redirects Stderr to Stdout, & tees the output to the screen and a logfile
	# [2021Feb22 MCK] - updated to re-write the leading '.' character when scripts from the current directory are executed
	# [2022Nov03 MCK] - commented out conditional around shortname test on line 27/28 since the '[[' causes errors
	# [2024Dec05 MCK] - Adding log heading to fully print CMD before running it

	It is often useful to figure out which OS X command/process is listening on a specific IP port

	On Linux this can be done with the `netstat -p`

	On OS X, the process id along with a lot of other info can be can be shown using the verbose `-v` flag:
	* `sudo netstat -anlv \|grep -e Address -e LISTEN` - will display the LISTENing processes along with the column header

	This variant outputs a comman-delimited list of the processes that are LISTENing:
	* `sudo netstat -anlv \|grep -e LISTEN \| awk '{print $9}'\| sort -nu\| tr "\n" "," \| sed s/,$//`
