CONVERT: GIT SHELL to GIT BATCH script

Question

I need some help how can I edited this code from a shell script to batch script, since i want to run it also in windows.

 #!/bin/bash
 commit_limit='4'
 log=`git show HEAD~$commit_limit --pretty=format:"%H" --no-patch`

 echo $log > .git/info/grafts
 git filter-branch -f -- --all
 rm .git/info/grafts
 git update-ref -d refs/original/refs/heads/master  
 git reflog expire --expire=now --all
 git gc --force --prune=now --aggressive
 git push --force origin $branch

i tried this but it give me an output "H" instead of "9b027aaccb996ae4895e4dfb428c5e6e24870e68"

SET commit_limit=4
git show HEAD~%commit_limit% --pretty=format:"%H" --no-patch
pause

i tried this but it give me an output "H" @echo off SET commit_limit=4 git show HEAD~%commit_limit% --pretty=format:"%H" --no-patch pause — rkevx21

Batch File does not work but works in cmd with this command: git show HEAD~4 --pretty=format:"%H" --no-patch — rkevx21

In variable you have to escape percent sign (%) with double percent (%%).
replaced / with \ in del command.
$branch is a shell variable. I fixed to batch syntax %branch%, you have to edit this variable.

@echo off

setlocal
rem edit branch variable
set "branch=branch"

set "commit_limit=4"
set "log=git show HEAD~%%commit_limit%% --pretty=format:"%%H" --no-patch"

%log% > .git\info\grafts

git filter-branch -f -- --all
del .git\info\grafts
git update-ref -d refs/original/refs/heads/master  
git reflog expire --expire=now --all
git gc --force --prune=now --aggressive
git push --force origin %branch%
