how to create a file and make it executable in one command?
how to create a file and make it executable in one command?
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?

Write an alias/function to do it and add to your bashrc.
function nanox() { nano "$1" chmod +x "$1" }-
This is the way.

You could define a function that takes a parameter, which touches a file with the parameters value, chmods it and then opens it with nano?
create_exec() { touch "$1" chmod +x "$1" nano "$1" }Then you could type
create_exec file.shand it would do the rest for you. -
Here's one I have saved in my shell aliases.
nscript() { local name="${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.

Use
&&to use multiple commands one after the other, don't use;.-
&&means execute if the command before ended successfully||means execute if the commnad before failed;just means execute the command - no matter if succeeded or failed-
My dude, thanks for this. I've been using && for a long time now but never knew the rest, I'm still pretty new to linux comparatively.

touch file && chmod +x file -
You could append the chmod command with && but that's probably not what you wanted.

You mean like
touch file && chmod +x file?Wrap it up folks, we're done here.
