Konversi akhir baris untuk seluruh pohon direktori (Git)

Situasi berikut:

Saya sedang mengerjakan Mac yang menjalankan OS X dan baru-baru ini bergabung dengan sebuah proyek yang anggotanya semua menggunakan Windows. Salah satu tugas pertama saya adalah mengatur basis kode dalam repositori Git, jadi saya menarik pohon direktori dari FTP dan mencoba memeriksanya ke repo Git yang telah saya siapkan secara lokal. Ketika mencoba melakukan ini, yang saya dapatkan adalah ini

fatal: CRLF would be replaced by LF in blog/license.txt.

Karena ini mempengaruhi semua file di bawah folder "blog", saya mencari cara untuk dengan mudah mengkonversi SEMUA file di pohon ke Unix line-endings. Apakah ada alat yang melakukannya di luar kotak atau apakah saya mendapatkan skrip sendiri?

Untuk referensi, konfigurasi Git saya tentang akhir baris:

core.safecrlf=true
core.autocrlf=input

dos2unix melakukan itu untuk Anda. Proses ke depan yang cukup lurus.
dos2unix filename

Berkat toolbear, ini adalah one-liner yang secara rekursif menggantikan akhir baris dan menangani spasi, kutipan, dan shell meta chars dengan benar.

find . -type f -exec dos2unix {} \;

Jika Anda menggunakan file biner dos2unix 6.0 akan diabaikan.

Dengan asumsi Anda memiliki GNU grepdan perlini akan secara rekursif mengkonversi CRLF ke LF dalam file non-biner di bawah direktori saat ini:

find . -type f -exec grep -qIP '\r\n' {} ';' -exec perl -pi -e 's/\r\n/\n/g' {} '+'

Bagaimana itu bekerja

Temukan secara rekursif di bawah direktori saat ini; ubah .ke blogatau whatevsubdirektori untuk membatasi penggantian:

find .

Hanya cocok dengan file biasa:

  -type f

Uji apakah file berisi CRLF. Kecualikan file biner. Menjalankan grepperintah untuk setiap file biasa. Itu harga tidak termasuk binari. Jika Anda memiliki yang lama, grepAnda bisa mencoba membuat tes menggunakan fileperintah:

  -exec grep -qIP '\r\n' {} ';'

Ganti CRLF dengan LF. The '+'dengan yang kedua -execmemberitahu finduntuk mengakumulasi file yang cocok dan meneruskannya ke satu (atau sesedikit mungkin) pemanggilan perintah seperti perpipaan xargs, tetapi tanpa masalah jika path file berisi spasi, tanda kutip, atau karakter meta shell lainnya. The idalam -pimemberitahu perl untuk memodifikasi file di tempat. Anda dapat menggunakan sedatau di awksini dengan beberapa pekerjaan, dan Anda mungkin akan mengubah '+' menjadi ';' dan meminta proses terpisah untuk setiap pertandingan:

  -exec perl -pi -e 's/\r\n/\n/g' {} '+'

Ini pilihan yang lebih baik: Pisau File Swiss . Ia bekerja secara rekursif di seluruh sub-direktori, dan menangani spasi dan karakter khusus dengan benar.

Yang harus Anda lakukan adalah:

sfk remcr -dir your_project_directory

Bonus: sfk juga melakukan banyak konversi lainnya. Lihat di bawah untuk daftar lengkap:

   help by subject
      sfk help select   - how dirs and files are selected in sfk

      sfk help chain    - how to combine (chain) multiple commands

      sfk help colors   - how to change result colors
      sfk help xe       - for infos on sfk extended edition.

   All tree walking commands support file selection this way:

   1. short format with ONE directory tree and MANY file name patterns:
      src1dir .cpp .hpp .xml bigbar !footmp
   2. short format with a list of explicite file names:
      letter1.txt revenues9.xls report3\turnover5.ppt
   3. long format with MANY dir trees and file masks PER dir tree:
      -dir src1 src2 !src\save -file foosys .cpp -dir bin5 -file .exe

   For detailed help on file selection, type "sfk help select".

   * and ? wildcards are supported within filenames. "foo" is interpreted
   as "*foo*", so you can leave out * completely to search a part of a name.
   For name start comparison, say "\foo" (finds foo.txt but not anyfoo.txt).

   When you supply a directory name, by default this means "take all files".

      sfk list mydir                lists ALL  files of mydir, no * needed.
      sfk list mydir .cpp .hpp      lists SOME files of mydir, by extension.
      sfk list mydir !.cfg          lists all  files of mydir  EXCEPT .cfg

   general options:
      -tracesel tells in detail which files and/or directories are included
                or excluded, and why (due to which user-supplied mask).
      -nosub    do not process files within subdirectories.
      -nocol    before any command switches off color output.
      -quiet    or -nohead shows less output on some commands.
      -hidden   includes hidden and system files and dirs.
      For detailed help on all options, type "sfk help options".

   beware of Shell Command Characters.
      command parameters containing characters < > | ! & must be sur-
      rounded by quotes "". type "sfk filter" for details and examples.

   type "sfk ask word1 word2 ..."   to search ALL help text for words.
   type "sfk dumphelp"              to print  ALL help text.

EDIT: kata hati-hati: hati-hati saat menjalankan ini pada folder yang memiliki file biner, karena akan secara efektif menghancurkan file Anda, khususnya direktori .git . Jika ini adalah kasus Anda, jangan tidak menjalankan sfk di seluruh folder, tapi pilih ekstensi file tertentu bukan (* Rb, * .py, dll). Contoh:sfk remcr -dir chef -file .rb -file .json -file .erb -file .md

find . -not \( -name .svn -prune -o -name .git -prune \) -type f -exec perl -pi -e 's/\r\n|\n|\r/\n/g' {} \;

Ini jauh lebih aman karena tidak merusak git repo Anda. Tambahkan atau ganti .git, .svn dengan .bzr, .hg atau sumber apa pun yang mengontrol penggunaan Anda ke daftar tidak .

Di OS X, ini berhasil bagi saya:

find ./ -type f -exec perl -pi -e 's/\r\n|\n|\r/\n/g' {} \;

Peringatan: Harap cadangkan direktori Anda sebelum menjalankan perintah ini.

Di sini solusinya jika menggunakan sed:

find . -type f -exec sed -i 's/\r$//' {} \;

-i singkatan di tempat, jika Anda ingin membuat cadangan gunakan juga -i.bak

's/\r$//'akan mengganti semua pengembalian carriage ( \r) di akhir setiap baris
