Convert Linux script

#1 Post by Dingo » 21 Dec 2019 23:51

I have a Linux script that I got to work on Ubuntu but I need the same script to run on Windows. The main bit from the Linus script is

Code: Select all

n=100;
max=200;
while [ "$n" -le "$max" ]; do
   echo "$passwd"> /usr/bin/multiboinc/BOINC_"$n"/gui_rpc_auth.cfg;
   echo "BOINC_$n $passwd";

   n=`expr "$n" + 1`;
done
I have tried a bunch of things but I do not know the syntax in Windows. This is what I eventually had:

Code: Select all

set /P passwrd=aussie
echo $passwrd
FOR /L %X IN (100,1,102) DO (
   break> /mnt/c/multiboinc/BOINC_"$n"/gui_rpc_auth.cfg;
   echo $passwd> C:\multiboinc\BOINC_$X\gui_rpc_auth.cfg
echo BOINC_$X
   X=`expr $X + 1`)
DONE
but it gives an error message
C:\multiboinc>passwd_change.bat

C:\multiboinc>set /P passwrd=aussie
aussie

C:\multiboinc>echo $passwrd
$passwrd

C:\multiboinc>set /A X=0
X was unexpected at this time.

C:\multiboinc>FOR /L X IN (100,1,102) DO (

The error is about a SET /A statement that you don't have in your snippet anymore.
Try:

Code: Select all

@echo off &setlocal

set /p "passwrd=Enter your password: "
set /a "n=100,max=200"

setlocal EnableDelayedExpansion
for /l %%X in (%n%,1,%max%) do (
  if not exist "C:\multiboinc\BOINC_%%X\" md "C:\multiboinc\BOINC_%%X"
  >"C:\multiboinc\BOINC_%%X\gui_rpc_auth.cfg" echo(!passwrd!
)
endlocal
FWIW: In case you are on a Win10 64Bit you can install the Windows Subsystem For Linux (WSL) and run your Linux Shell script as is.

Thanks that works like a charm:

I have an old laptop with windows 10 that does not have much space left so just need a script for that. I will also put this code on our forum for those that do not know anything about Linux.

Thanks again. I have another script that I am trying to run and if I still can't get it to work by bedtime I will post again.
