Create file along with nested directory in single command line - linux

Question

I want to create a file abc.php within a directory a/b/c which does not exist yet. I need to do it with a single command like this mkfile a/b/c/abc.php I checked this solution which suggests solution like this mkfile a/b/c abc.php.
And along with this I would love to have the file opened in an editor which happens with nano command.
Usually while following tutorials we have to create file and copying and pasting their file directory without editing makes life simpler.

If I understand correctly and you simply want to be able to issue command foo/bar/baz/myfile.txt (or something similar) and have the directories foo/bar/baz created and a new file myfile.txt created and opened in nano all by that one command, then a short script is all you need, e.g.
Make it executable e.g. mv nanoopen.sh scriptname; chmod 0755 scriptname, then just call ./scriptname foo/bar/baz/file.txt. If you put it in your path, you can skip the ./ too.
The easy way to put it in your path is to create a symlink to it in /usr/local/bin which is generally in the default path.
So you could (sometime supersure is needed) ln -s /path/to/nanoopen.sh /usr/local/bin/scriptname. Echo $PATH to confirm /usr/local/bin is in your path, then just use it like any program, scriptname arguments.
Or in some distros you can simply add it to /bin folder with root access.
#!/bin/bash
[ -z "$1" ] && { ## validate one argument given
printf "error: insufficient input\nusage: %s filename\n" "${0##*/}"
exit 1
}
[ "$1" != "${1##*/}" ] && mkdir -p "${1%/*}" ## if it has directories, create
touch "$1" ## create the file
exec nano "$1" ## open in nano
Example Use/Output
$ bash nanoopen.sh foo/bar/baz/main.c
$ tree foo/
foo/
└── bar
└── baz
└── main.c
$ cat foo/bar/baz/main.c
