Copy the following code, save it to the text document, modify the suffix to bat
Drag the file that needs to be prefixed to the script to run
Procedure requirements:
Can be used by dragging
Rename without mechanically rigid
Keep original file name
Add a prefix before the original file name
Do not change the file suffix
Don’t look at a short line of code, it’s as difficult as breaking a code.
Both of the following are acceptable, but I prefer the latter, which is more concise:
ren "%~1" "181002304_海月_%~n1%~x1"
ren% 1 181002304_Kaigetsu_% ~ n1% ~ x1
Tips：
Drag in a file
File full name%~nx1
File name%~n1
Extension %~x1
%1 The first parameter refers to a string separated by spaces after the batch file name
If you drag and drop a file onto the script, then %1 represents this file, which is the first parameter
(You can use the shift command to shift the parameters to get more parameters)
%0 batch itself
Wildcard
Generally used for file name matching operations on the path
* Represents all characters
? Only represents one character
For example, copy all files in a folder copy path\*.* path
Copy files with the specified suffix copy path\*.jpg path
Copy the file whose first word is new and the last word is arbitrary, and the file name is limited to two words copy new?.xlsx path
One key to modify suffix
if exist "*.txt" (ren *.txt *.bat) else (ren *.bat *.txt)
:: The suffix of this file is cmd, which will not affect the use and will not be modified by itself
It is convenient to hand in the homework now~
