Question

I\'m using Ubuntu 13.10 x64, and I am working on a project that some developers are using Windows , I recently changed the git config core.eol to \"lf\" and

Answer 1

This happened to me on thousands of files. So I wrote a quick bash script to make dos2unix fix it for me. Someone else on Linux or Mac might find it useful.

#!/usr/bin/env bash

unwindows() {

  local errmsg
  local fpath

  # base case
  errmsg="$(git add . 2>&1)"
  if [[ $? -eq 0 ]]; then
    echo 'Successfully converted CRLF to LF in all files.'
    echo 'Successfully ran "git add .".'
    echo 'Done.'
    return 0
  fi

  fpath="${errmsg#*fatal: CRLF would be replaced by LF in }"
  fpath="${fpath%.*}"

  if [[ "${fpath}" == "${errmsg}" ]]; then
    err 'Regex failed. Could not auto-generate filename from stderr.'
    return 1
  fi

  if [[ ! -e "${fpath}" ]]; then
    err "Regex failed. '${fpath}' does not exist."
    return 1
  fi

  if ! dos2unix "${fpath}"; then
    err "Failed to run \"dos2unix '${fpath}'\"."
    return 1
  fi

  # recursive case
  unwindows
}

err() {
  local -r msg="$1"
  echo "${msg}" >&2
}

unwindows

Basically, it tries to do git add .. If the command fails, it grabs the name of the incompatible file from the error output. Then it runs dos2unix on that file. It keeps repeating this process until git add . works.

If you run this, you should see dos2unix: converting file xxx to Unix format... repeatedly. If you don't, it's not working, so just press ctrl+c or command+c to stop it.
