[linux] One command to create a directory and file inside it linux command

Suppose my current directory is A. I want to create a directory B and a file "myfile.txt" inside B.

How to do that in one command from Terminal?

Edit:

Directory can be nested multiple times. Like I may want to create B/C/D and then "myfile.txt" inside that. I do not also want to repeat the directory part.

Following command will create directory at any level.

mkdir -p B/C/D 

and

mkdir -p B/C/D && touch B/C/D/myfile.txt

will create the directory and the file. But I do not want to repeat the directory part after the touch command. Is that possible?

devnull's answer provides a function:

mkfile() { mkdir -p -- "$1" && touch -- "$1"/"$2" }

This function did not work for me as is (I'm running bash 4.3.48 on WSL Ubuntu), but did work once I removed the double dashes. So, this worked for me:

echo 'mkfile() { mkdir -p "$1" && touch "$1"/"$2" }' >> ~/.bash_profile
source ~/.bash_profile
mkfile sample/dir test.file

Below commands I tried on Windows 10 machine with git-bash. And that worked for me. Let's say I want to create a directory named "Files" and under this directory I want to have "file1.txt,file2.txt,file3.txt" ..etc files

mkdir Files && touch $_/file1.txt $_/file2.txt $_/file3.txt

mkdir -p Python/Beginner/CH01 && touch $_/hello_world.py

Explanation: -p -> use -p if you wanna create parent and child directories $_ -> use it for current directory we work with it inline

You could create a function that parses argument with sed;

atouch() {
  mkdir -p $(sed 's/\(.*\)\/.*/\1/' <<< $1) && touch $1
}

and then, execute it with one argument:

atouch B/C/D/myfile.txt

Just a simple command below is enough.

mkdir a && touch !$/file.txt

Thx

add this to ~/.bashrc:

function mkfile() { 
    mkdir -p  "$1" && touch  "$1"/"$2" 
}

save and then to make it available without a reboot or logout execute: $ source ~/.bashrc or you can just do:

$ mkdir folder && touch $_/file.txt

note that $_ = folder

For this purpose, you can create your own function. For example:

$ echo 'mkfile() { mkdir -p "$(dirname "$1")" && touch "$1" ;  }' >> ~/.bashrc
$ source ~/.bashrc
$ mkfile ./fldr1/fldr2/file.txt

Explanation:

• Insert the function to the end of ~/.bashrc file using the echo command
• The -p flag is for creating the nested folders, such as fldr2
• Update the ~/.bashrc file with the source command
• Use the mkfile function to create the file

you can install the script ;

pip3 install --user advance-touch

After installed, you can use ad command

ad airport/plane/captain.txt

airport/
+-- plane/
¦   +-- captain.txt

This might work:

mkdir {{FOLDER NAME}}
cd {{FOLDER NAME}}
touch {{FOLDER NAME}}/file.txt
