Use the Python child process module to run batch files with more than 10 parameters
I’m using this code:
Test .py:
cmd_line = str('C:\mybat.bat') + " "+str('C:\')+" "+str('S:\Test\myexe.exe')+" "+str('var4')+" "+str('var5')+" "+str('var6')+" "+str('var7')+ " "+str('var8') + " "+str(' var9')+ " "+ str('var10')
process = subprocess. Popen(cmd_line, stdin=PIPE, stderr=None, stdout=None, shell=True)
process.communicate()
retcode = process.returncode
mybat.bat:
cd /d %1
%2 %3 %4 %5 %6 %7 %8 %9 %10
It works fine before the parameter: “var10” because I don’t know why bat takes the same value for %1 instead of %10, as shown below:
... >cd /d C:\
C:\> S:\Test\myexe.exe var4 var5 var6 var7 var8 var9 C:\0
I want to read the last parameter var10, not C:\0 because bat it takes the value of var1 and only adds 0, but it should be var10.
Thanks!
Solution
Batch files only support %1 through %9. To read the 10th parameter (and the next and next arguments), you must use the command (possibly more times).
shift
Change parameters:
10 parameters to %9, %9 to %8, and so on:
+--------------+----+----+----+----+----+----+----+----+----+----+------+
| Before shift | %0 | %1 | %2 | %3 | %4 | %5 | %6 | %7 | %8 | %9 | 10th |
+--------------+----+----+----+----+----+----+----+----+----+----+------+
| After shift | x | %0 | %1 | %2 | %3 | %4 | %5 | %6 | %7 | %8 | %9 |
+--------------+----+----+----+----+----+----+----+----+----+----+------+
( x means that the original %0 is now inaccessible, so if you need it, you must use it before the shift statement.)
).
Now you can use the 10th parameter as %9, the 9th parameter as %8, and so on.
So change your batch file:
cd /d %1
shift
%1 %2 %3 %4 %5 %6 %7 %8 %9
