Ms-DOS For Loop
After a long time, I used good old Ms-DOS to recursively delete large number of directories (~2500+) in Windows. A simple for loop like below is useful to do the same,
To list the directories -
FOR /F "delims=" %i IN ('dir /s /b /ad <directory name>') DO @echo "%i"
To delete the directories -
FOR /F "delims=" %i IN ('dir /s /b /ad <directory
name>') DO rmdir /S /Q "%i"
/F - Option to process the output of a command or file list. If it is not mentioned, then the whole section after "IN" with the "dir" command will be treated as a string.
delims= - Delimiter character. The default value is space & tab. Note - If not overridden as above or never mentioned in the command, the output gets chopped at the space if a directory name has any spaces. In the above scenario, the delimiter will be the end of line.
dir - Directory listing command with options,
- /s - Display
files in the specified directory & sub-directories
- /b - Bare bones
listing without time-stamp, volume or file size info.
- /a - Display
files with specified attributes. In this case,
- d - to display
directories only.
