# define usage function to echo syntax if no args given

# define copyall function
copyall() {
# local variable to take the first argument as file
local file="$1" dir
# shift to the next argument(s)
shift
# loop through the next argument(s) and copy $file to them
for dir in "$@"; do
cp -R "$file" "$dir"

# function to check if filename exists
# $f -> store argument passed to the script
file_exists(){
local f="$1"
[[ -f "$f" ]] && return 0 || return 1
}
# call usage() function to print out syntax
[[ $# -eq 0 ]] && usage
これが私が理解できないものです
# call file_exists() and copyall() to do the dirty work
if ( file_exists "$1" ) then
copyall
また、この次のエコー セクションを 1 行にまとめる方法を見つけたいと思っています。$1 の代わりに、シフトして次に進みます。多分それを配列に分割しますか?
echo "copyall: File $1 was copied to"
shift
echo "$@ on $date by $usr"
else
echo "Filename not found"
fi
exit 0
