ls $TARGET_DIR mv

for f in : ls $TARGET_DIR mv

ls $TARGET_DIR mv "

ls $TARGET_DIR mv

for f in 'ls $TARGET_DIR' do mv..., not sure where it is correct, from my experience the most similar i can run is: for f in $(ls $TARGET_DIR) do mv.... can someone elaborate? thanks

$TARGET_DIR/* mv

I don't get this script... Shouldn't it be something like this: for f in *; do mv $f $(openssl sha256 -r < $f | cut -d " " -f 1); done I tried with 'ls $TARGET_DIR' and it just prints the command which results in an error: "mv: cannot stat 'ls': No such file or directory" Regarding the cut command we can use either -f or -c according to documentation, why are they using both? Also the default delimiter is TAB which would result in the string having 'stdin' at the end. We need to change that with the -d option.
