git之gitignore

• blank lines or lines starting with # are ignored
• stardard glob patterns work
  • * matches zero or more characters
  • [abc] matches any character inside the brackets
  • [0-9] matches any character between them
  • a/**/z matches a/z, a/b/z, a/b/c/z, and so on
• negate a pattern by starting it with an !

示例：

*.a     # 所有已 .a 结尾的文件
!lib.a  # 将跟踪 lib.a，即使 *.a
/TODO   # 仅忽略顶层TODO，而不是 subdir/TODO
build/  # 忽略build/文件夹下所有文件
doc/*.txt     # 忽略 doc/notes.txt，但不忽略doc/server/arch.txt
doc/**/*.txt  # 忽略所有doc/文件夹下的所有 .txt 文件，包括doc/*.txt
