To start learning type help
at the command prompt. Then anything on that list add /?
for more help.
Set /p NewName=Enter project name
md "c:somewhere\%newname%project\%newname% software
md "c:somewhere\%newname%project\%newname% hardware
or use xcopy (and use/l
to have it do a test without copying)
xcopy "c:empate" "d:\%newname%" /e /h /q /i /c
See set /?
, md /?
, and xcopy /?
. Type just set
to see a list of variables.
& seperates commands on a line.
&& executes this command only if previous command's errorlevel is 0.
|| (not used above) executes this command only if previous command's errorlevel is NOT 0
> output to a file
>> append output to a file
< input from a file
| output of one command into the input of another command
^ escapes any of the above, including itself, if needed to be passed to a program
" parameters with spaces must be enclosed in quotes
+ used with copy to concatinate files. E.G. copy file1+file2 newfile
, used with copy to indicate missing parameters. This updates the files modified date. E.G. copy /b file1,,
%variablename% a inbuilt or user set environmental variable
!variablename! a user set environmental variable expanded at execution time, turned with SelLocal EnableDelayedExpansion command
%<number> (%1) the nth command line parameter passed to a batch file. %0 is the batchfile's name.
%* (%*) the entire command line.
%<a letter> or %%<a letter> (%A or %%A) the variable in a for loop. Single % sign at command prompt and double % sign in a batch file.
\ (\servernamesharenamefolderfile.ext) access files and folders via UNC naming.
: (win.ini:streamname) accesses an alternative steam. Also separates drive from rest of path.
. (win.ini) the LAST dot in a file path seperates the name from extension
. (dir .*.txt) the current directory
.. (cd ..) the parent directory
\? (\?c:windowswin.ini) When a file path is prefixed with \? filename checks are turned off.
< > : " / | Reserved characters. May not be used in filenames.
Reserved names. These refer to devices eg,
copy filename con
which copies a file to the console window.
CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4,
COM5, COM6, COM7, COM8, COM9, LPT1, LPT2,
LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9
CONIN$, CONOUT$, CONERR$
Maximum path length 260 characters
Maximum path length (\?) 32,767 characters (approx - some rare characters use 2 characters of storage)
Maximum filename length 255 characters
Starting a Program
===============
See start /? and call /? for help on all three ways.
Specify a program name
--------------------------------
c:windows
otepad.exe
In a batch file the batch will wait for the program to exit. When
typed the command prompt does not wait for graphical
programs to exit.
If the program is a batch file control is transferred and the rest of the calling batch file is not executed.
Use Start command
--------------------------
start "" c:windows
otepad.exe
Start starts a program and does not wait. Console programs start in a new window. Using the /b switch forces console programs into the same window, which negates the main purpose of Start.
Start uses the Windows graphical shell - same as typing in WinKey + R (Run dialog). Try
start shell:cache
Use Call command
-------------------------
Call is used to start batch files and wait for them to exit and continue the current batch file.
