remsync

#!/usr/bin/env bash
# helper script for syncing files to my server using rsync
# this syncs a copy of the directory, if you delete files
# locally, it deletes it up on the remote
#
# remsync [FILE...] [DIR...]
#
# If files/directories are passed as arguments, they're copied to
# $FROM_DIR and are then pushed to the server
#
# to delete remote files for REMSYNC_PUBLIC, set REMSYNC_DELETE=1
#
# files are served by nginx as static files, with:
#
# private remsync
#
# rewrite ^/f$ /f/ permanent;
#
# location /f/ {
#   alias /home/sean/f/;  # location
#
#   # dont serve directories
#   try_files $uri =404;
#   autoindex off;
#
#   # make sure files are downloaded instead of viewed
#   expires -1;
#   default_type application/octet-stream;
# }
#
# public remsync
#
# rewrite ^/p$ /p/ permanent;
#
# location /p/ {
#   alias /home/sean/p/;  # location
#   try_files $uri $uri/ =404;
#   autoindex on;
#   autoindex_exact_size off;
#   autoindex_localtime on;
