Auto sync GIT repos in MAC

Use the following to auto-commit your changes in git repo. The commit will include the file changed. You can control the monitor interval by changing the variable sleeptime in git-commit-repos.sh. All the git operations are logged in /tmp/gitwatch-commit.log.

Use cases:

  • syncing your notes repository automatically eg. Sublime ZK

Requirements:

Steps:

  • Make sure all the required softwares are installed
  • Create new folder gitwatch in your home folder
  • Copy git-commit-repos.sh and git-commit-unattended.sh files in the gitwatch folder
  • git-commit-repos.sh
#!/bin/bash
# send notification on start 
/usr/local/opt/terminal-notifier/bin/terminal-notifier -title "Status" -message "Gitwatch online."

repos=(
"/Users/dev/git/scripts"
"<ANOTHER REPO PATH>"
"<YET ANOTHER REPO PATH>"
);

path="$HOME/gitwatch/"
sleeptime=600

for repo in ${repos[*]}
do
 /usr/local/opt/terminal-notifier/bin/terminal-notifier -title "Gitwatch" -message "working on $repo"
 running=$(ps aux | grep -wv "^\s*$$" | grep -v "grep" | grep "/usr/local/opt/fswatch/bin/fswatch" | grep $repo | wc -l);

 ## exit if already running
 if [ $running -gt 0 ];then
  /usr/local/opt/terminal-notifier/bin/terminal-notifier -title "Gitwatch" -message "Exiting on $repo"
  exit 0;
