Backup all contents of current directory to a subdirectory inside the current directory, which will be created if not exists
Clash Royale CLAN TAG#URR8PPP
Right now I have following command to copy all contents of the current directory to sub-directory, provided if the subdirectory is created in advance:
cp -p !($PWD/bakfiles2) bakfiles2/
But I have to some times visit those folders which I have never visited before, so sub-directory "bakfiles2" may not exist there, can I somehow create that backup directory with current timestamp(as to avoid conflictions with any existing directory), on the fly when with single copy command or bash script ?
It would be great if the script can ignore any sub-directory starting with a particular pattern which could then be reserved for backup directory names like _bak_* (Note: * means any number of any characters).

cp command doesn't have an option to create destination directory if doesn't exist while coping, but you can achieve with scripting.
or simply use rsync command which can create destination directory if doesn't exist only on last level.
rsync -rv --exclude='_bak_*/' /path/in/source/ /path/to/destination
- note that leading
/in/path/in/source/will prevent coping source directory itself and adding--excludeoption to don't sync directories with matched name.

You can copy the contents of a directory only to a directory that already exists, unless you're using a recursive copy. However, you can't use a recursive copy unless you want the previous backup directories also copied to the new backup directory.
So this has to be done in a couple of steps
backup_dir="_bak_$(date +'%Y%m%d_%H%M%S')"
mkdir "$backup_dir"
cp -p !(_bak_*) "$backup_dir/"
Bear in mind that as written this will not copy dot files (files beginning with a . character), since these are usually treated specially by the shell. (You might want to consider naming your backup directory .bak_* instead of _bak_* to benefit from this feature. You can then cp -p * "$backup_dir/")
There's no reason why this couldn't created as a little function or script, so it's then still only one command.
