Sync permissions bez obsahu souboru

Pokud se nam povedlo syncnout adresar bez setuidu nebo numeric-ids, a zjistime to se zpozdenim kdyz uz jsou data zmenena a chcem permisny dosyncnout dodatecne na upraveny produkcni data bez zmeny obsahu souboru, muzem pouzit tenhle skript:

psync.sh

#!/bin/bash
#set -x
 
fixperms() {
	echo "FIXING $SUFFIX in $@ $(date)"
	cd "$3""$SUFFIX"
	IFS=$'\t'
	ssh "$1" -- 'find '"$2$SUFFIX"' -printf "%m\t%U:%G\t%u:%g\t%P\n"' | tail -n +2 | while read -a line; do
		#echo chown -h "${line[2]}" "${line[3]}"		#set name ids (probably bad for migrations?)
		chown -h "${line[1]}" "${line[3]}"			#set numeric ids
		test -L "${line[3]}" || chmod "${line[0]}" "${line[3]}"	#set mode if not symlink
	done;
}
 
#SUFFIX=/home
