Bash string concatenation used to build parameter listview story

http://unix.stackexchange.com – Given this piece of bash: PARMS='-rvu' PARMS+=" --delete --exclude='.git'" echo $PARMS rsync ${PARMS} . ${TARGET} The echo shows the PARMS string as expected, no error is displayed, but rsync silently acts as if the options added by the += did not exist. However, this works as expected: PARMS='-rvu' rsync ${PARMS} --delete --exclude='.git' . (HowTos)
