BASH copy all files except one
rsync has been my cp/scp replacement for a long time:
rsync -av from/ to/ --exclude=Default.png
-a, --archive archive mode; equals -rlptgoD (no -H,-A,-X)
-v, --verbose increase verbosity
Should be as follows:
cp -r !(Default.png) /dest
If copying to a folder nested in the current folder (called example in the case below) you need to omit that directory also:
cp -r !(Default.png|example) /example
