CodePudding user response：

Simply use curly braces around the directories and files when creating the files with touch

touch {dir1,dir2,dir3}/{f1.txt,f2.txt,f3.txt}

touch command create multiple files (different names) under one directory

CodePudding user response：

I'm not sure I understand your question;

If you just need to create those 9 files in one command, simply use

touch dir1/f1.txt dir1/f2.txt dir1/f3.txt dir2/f1.txt ...
