git diff -p     grep -E    diff old mode new mode       sed -e  s  old NEW  s  new old  s  NEW new       git apply   will work in most cases but if you have external diff tools like meld installed you have to add --no-ext-diff  git diff --no-ext-diff -p         grep -E    diff old mode new mode           sed -e  s  old NEW  s  new old  s  NEW new           git apply   was needed in my situation

Git keeps track of filepermission and exposes permission changes when creating patches using git diff -p  So all we need is    create a reverse patch include only the permission changes apply the patch to our working copy   As a one-liner   git diff -p -R --no-ext-diff --no-color         grep -E    diff  old new  mode   --color never          git apply   you can also add it as an alias to your git config     git config --global --add alias permission-reset   git diff -p -R --no-ext-diff --no-color   grep -E    diff  old new  mode   --color never   git apply       and you can invoke it via   git permission-reset   Note  if you shell is bash  make sure to use   instead of   quotes around the  git  otherwise it gets substituted with the last git command you ran   Thx to  Mixologic for pointing out that by simply using -R on git diff  the cumbersome sed command is no longer required

You could also try a pre post checkout hook might do the trick   See  Customizing Git - Git Hooks

Git doesn t store file permissions other than executable scripts  Consider using something like git-cache-meta to save file ownership and permissions   Git can only store two types of modes   755  executable  and 644  not executable    If your file was 444 git would store it has 644

The easiest thing to do is to just change the permissions back   As  kroger noted git only tracks executable bits   So you probably just need to run chmod -x filename to fix it  or  x if that s what s needed

The etckeeper tool can handle permissions and with   etckeeper init -d  mydir   You can use it for other dirs than  etc   Install by using your package manager or get sources from above link

Try git config core fileMode false  From the git config man page      core fileMode      If false  the executable bit differences between the index and the working copy are ignored  useful on broken filesystems like FAT  See git-update-index 1        The default is true  except git-clone 1  or git-init 1  will probe and set core fileMode false if appropriate when the repository is created

Thanks  muhqu for his great answer  In my case not all changes files had permissions changed which prevented the command to work    git diff -p -R --no-ext-diff --no-color   grep -E  quot   diff  old new  mode  quot  --color never diff --git b file1 a file1 diff --git b file2 a file2 old mode 100755 new mode 100644   git diff -p -R --no-ext-diff --no-color   grep -E  quot   diff  old new  mode  quot  --color never   git apply warning  file1 has type 100644  expected 100755  The patch would then stop and files would be left untouched  In case some people have similar problem I solved this by tweaking the command to grep only files with permission changed  grep -E  quot  old mode  100644 100755  quot  -B1 -A1  or for the git alias git config --global --add alias permission-reset   git diff -p -R --no-ext-diff --no-color   grep -E  quot  old mode  100644 100755  quot  -B1 -A1 --color never   git apply

I use git from cygwin on Windows  the git apply solution doesn t work for me  Here is my solution  run chmod on every file to reset its permissions      bin bash IFS    n  for c in  git diff -p  sed -n   diff --git  N s diff --git  g s  n   g s  a    b   g s old mode   g s        100       chmod  2  1 g p    do         eval  c done unset IFS

git diff -p used in muhqu s answer may not show all discrepancies     saw this in Cygwin for files I didn t own mode changes are ignored completely if core filemode is false  which is the default for MSysGit    This code reads the metadata directly instead    set -o errexit pipefail nounset  git ls-tree HEAD -z   while read -r -d    0  mask type blob path do     if     type      blob     then continue  fi      case   mask  in      do not touch other bits     100644  chmod a-x   path        100755  chmod a x   path           echo  invalid   mask  type  blob t path   gt  amp 2  false       esac done    A non-production-grade one-liner  replaces masks entirely    git ls-tree HEAD   perl -ne    10 0 d 3   blob  S  t        amp  amp    system  chmod   1  2    die       Credit for     0   goes to http   transnum blogspot ru 2008 11 bashs-read-built-in-supports-0-as html
