# Directory Sync Utility Script
|
||||
#
|
||||
# Watches a local directory for file changes and syncs them to a remote host
|
||||
# via SCP in real time. On exit (Ctrl+C), resets the remote repository and
|
||||
# clears the remote cache.
|
||||
#
|
||||
# Usage: ./dir-sync.sh [OPTIONS]
|
||||
#
|
||||
# Options:
|
||||
# -s, --source <path> Local directory absolute path
|
||||
# -d, --dest <path> Remote directory absolute path
|
||||
# -r, --remote-host <h> Remote SSH host
|
||||
# -h, --help Print this help
|
||||
#
|
||||
# Examples:
|
||||
# ./dir-sync.sh -s /var/www/myapp/ -d /var/www/myapp/ -r myserver
|
||||
# ./dir-sync.sh -s ~/projects/app/ -d /srv/app/ -r devhost
|
||||
#
|
||||
# Requirements:
|
||||
# fswatch, scp, ssh
