Use relative paths in the batch processing (. BAT) File

Generally, when the relative path of the batch processing file is processed, the starting position is the directory where the BAT file is located. For example, execute the BAT file in the D: \ XX directory, all operations on relative directories are executed under D: \ xx.

However, some commands require administrator permissions. Right-click and choose c: \ windows \ system32 as the administrator, which is not what we want at this time,

One solution is to add "cd d: \ xx" at the beginning of the batch processing line to enter the directory to modify its current location, however, you need to add an absolute path to the batch processing file. If you move the BAT file to another location, it cannot be used. In this case, a better way is to use "CD/d % ~ Dp0 "instead of" cd d: \ xx ".

To sum up, when writing a BAT file, you 'd better add "CD/d % ~ Dp0 "to unify the initial directory of the file.

For example, if auto. bat is in the folder D: \ my_bat \, the content of auto. bat is as follows:

CD/d % ~ Dp0
