Yesterday, I began to transfer my git configuration from my old machine to my new MacBook Pro. When I rename my file by doing this, an error occurred to me:
It seems like my Mac OS X cannot recognize
Readme file as same as
readme file. So I had to convert
readme file to
tmp_file and then
Readme file. In Linux, this command can work very well, but in Mac OS X, failed. This is the first time that I realized case-sensitive is so important. Except for this situation, I believe it is very dangerous if keep confusing the case.
Different operating systems (OS) have different case-sensitive level, that is why the same command upon can work well on Linux but fail on Mac OS X.
- case-sensitive OS: Linux, Solaris, BSD
- case-insensitive OS: Windows, Mac OS X
In my working pipeline, my file often transfers between Linux and Mac OS X, so I decided to convert all my filename under lowercase_with_underscore principle. The reasons behind this principle are:
- Easy to read, UPPERCASE_WITH_UNDERSCORE is hard to read
- Easy to distinguish a private file from system folder/file such as
Downloadsand so on
- Transfer file with lower risk (Every OSs can recognize your file correctly)
- I love underscore sign
