Windows 7 / Getting Started

Strings with Spaces Need Quotes

Many commands will accept parameters, and when the parameters include spaces, the parameter usually needs to be enclosed in quotes.

As an example, the Net Shell command (netsh) can be used to configure a lot of networking settings, including the properties for the network interface card (NIC). The default name for the wired network interface card is Local Area Connection. If you want to set the DNS IP address to 10.10.0.10 using netsh, you could use the following command:

netsh interface ipv4 set DNSServer "Local Area Connection" static 10.10.0.10

In this example, the name of the NIC is expected after the DNSServer parameter. Since "Local Area Connection" is enclosed in quotes, it's interpreted as the name of the NIC.

However, the following command (without the quotes) would be interpreted quite differently:

netsh interface ipv4 set DNSServer Local Area Connection static 10.10.0.10

In this example, Local would be interpreted as the name of the NIC and the netsh command would then try to interpret Area as a separate command. Since netsh doesn't have an Area command, the entire command would fail.

You can occasionally get away without using the quotes. For example, if you're at the root of C (C:\) and want to change to the Program Files folder (which has a space), the following command will work:

CD Program Files

This is only because the CD command has been programmed to accept it, but that wasn't always the case. You could also enter this command as

CD "Program Files"
