I am tired of creating a file with nano, saving it and then making it executable. Is there a command that makes it in one step?

Here's one I have saved in my shell aliases.

nscript() {
    local name="${1:-nscript-$(printf '%s' $(echo "$RANDOM" | md5sum) | cut -c 1-10)}"
    echo -e "#!/usr/bin/env bash\n#set -Eeuxo pipefail\nset -e" > ./"$name".sh && chmod +x ./"$name".sh && hx ./"$name".sh
}
alias nsh='nscript'

Admittedly much more complicated than necessary, but it's pretty full featured. first line constructs a filename for the new script from a generated 10 character random hash and prepends "nscript" and a user provided name.

The second line writes out the shebang and a few oft used bash flags, makes the file executable and opens in in my editor (Helix in my case).

The third line is just a shortened alias for the function.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
