Difference between forward and backslash [duplicate]

Answer 1

Microsoft operating systems (e.g. DOS and Windows) use backslashes (\), UNIX-based operating systems (e.g. Linux) use slashes (/).

The dot (.) means the current working directory, it's like saying "here". The double dot (..) means the parent directory.

Answer 2

Well, in most languages backslashes need to be escaped in string literals, slashes do not. Further backslashes only work on Windows, while slashes work pretty much everywhere.

On the other hand, when passing path names as arguments to Windows programs, using slashes might not work because many Windows programs use slashes to signify command line flags, so you need to use backslashes.

On . vs. ..: . is the current directory, .. is the parent directory.

Answer 3

The difference between slash and backslash in Windows are from my tests at least non-existing, but I believe that in earlier editions they used backslash. UNIX systems uses slash.

The difference between ./ and ../ is that ./ represents the position in the hierarchy where you are standing while ../ is the parent directory.

Answer 4

Backslash is used for:

File names in DOS and Windows, e.g. D:\documents\office, C:\java\jdk escape sequences in C, Unix, and other languages/systems that borrow the same syntax (C++, Java, etc.). For example, \n means newline and \t means tab.

Forward slash is used for:

• File names on Unix (and Mac OS X, since it is derived from Unix), e.g. /cs/student/jsmith/cs8/lab00, /Users/Shared/cs8/cTurtle.py.
• Web addresses (URLs), such as http://www.cs.ucsb.edu/~pconrad/cs8.
• Dividing in many programming languages, e.g. battingAvg = hits / atBats;
