Pipe command output into a batch variable
You can do this using the /P switch of the set command.
"The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty." - http://www.computerhope.com/sethlp.htm
Example:
dir > temp.txt
set /P diroutput= < temp.txt
Execute a command in every directory recursively
Replace command with the required command or batch file.
It will get called for each subdirectory of the current directory. And have the directory name as the parameter variable %1.
Example:
for /f "usebackq" %%d in (`"dir /ad/b/s"`) do COMMAND "%%d"
Set NTFS permissions from a batch file
This is done with the cacls command:
Example:
cacls file.txt /e /g everyone:w
This grants (/g) the user "everyone" write access. And only edits (/e) the permissions so that current permission are left unchanged.
