Can someone please help me to understand the command cd /d %~dp0
and its purposes. Again dos command is below
cd /d %~dp0
Please help me to get the meaning of it.
Let's dissect it. There are three parts:
cd
-- This is change directory command./d
-- This switch makes cd
change both drive and directory at once. Without it you would have to do cd %~d0 & cd %~p0
. (%~d0
Changs active drive, cd %~p0
change the directory).%~dp0
-- This can be dissected further into three parts:
%0
-- This represents zeroth parameter of your batch script. It expands into the name of the batch file itself.%~0
-- The ~
there strips double quotes ("
) around the expanded argument.%dp0
-- The d
and p
there are modifiers of the expansion. The d
forces addition of a drive letter and the p
adds full path.
