We have a Windows machine running SQL Server 2005, and we need to be able to run some database queries on it from a Linux box. What are some of the recommended ways of doing this? Ideally, we would want a command-line utility similar to sqlcmd on Windows.

Install first FreeTDS, then configure one of the two ODBC engines to use FreeTDS as its ODBC driver. Then use the commandline interface of the ODBC engine.
unixODBC has isql, iODBC has iodbctest
You can also use your favorite programming language (I've successfully used Perl, C, Python and Ruby to connect to MSSQL)
I'm personally using FreeTDS + iODBC:
$more /etc/freetds/freetds.conf
[10.0.1.251]
host = 10.0.1.251
port = 1433
tds version = 8.0
$ more /etc/odbc.ini
[ACCT]
Driver = /usr/local/freetds/lib/libtdsodbc.so
Description = ODBC to SQLServer via FreeTDS
Trace = No
Servername = 10.0.1.251
Database = accounts_ver8
sqsh was primarily an isql replacement for Sybase SQL Server (now ASE) but it works just fine for connecting to SQL Server (provided you use freetds).
To compile, simply point $SYBASE to freetds install and it should work from there. I use it on my Mac all day.
The best part of sqsh are the advanced features, such as dead simple server linking (no need to set up linked servers in SQL Server), flow control and looping (no more concatenating strings and executing dynamic SQL), and invisible bulk copy/load.
Anyone who uses any other command line tool is simply crazy! :)
pymssql is a DB-API Python module, based on FreeTDS. It worked for me. Create some helper functions, if you need, and use it from Python shell.
Mono contains an ADO.NET provider that should do this for you. I don't know if there is a command line utility for it, but you could definitely wrap up some C# to do the queries if there isn't.
Have a look at http://www.mono-project.com/TDS_Providers and http://www.mono-project.com/SQLClient
If you are using Java, have a look at JDBC.

You don't say what you want to do with the resulting data, but if it's general queries for development/maintenance then I'd have thought Remote Desktop to the windows server and then using the actual SQL Server tools on their would always have been a more productive option over any hacked together solution on Linux itself.
There is an abstraction lib available for PHP. Not sure what your client's box will support but if its Linux then certainly should support building a PHP query interface with this: http://adodb.sourceforge.net/ Hope that helps you.
I'd like to recommend Sqlectron. Besides being open source under MIT license it's multiplatform boosted by Electron. Its own definition is:
A simple and lightweight SQL client desktop with cross database and platform support
It currently supports PostgreSQL, MySQL, MS SQL Server, Cassandra and SQLite.
Surprised no one has mentioned that, contrary to what other answers seem to suggest, FreeTDS is all you need. No need for unixODBC, iODBC or anything else on top of it.
run some database queries [...] command-line utility similar to sqlcmd on Windows
tsql does this and is part of the FreeTDS package (as are freebcp and other utilities). tsql does not have fancy UI, but if you want a command-line utility that is light, functional and performant, it'll do just fine.
See e.g. How to run a SQL script in tsql
And by light, I mean under 500kb in size (maybe under 60k depending on how it's compiled) and, as far as I have seen, extremely efficient with memory and CPU.
valentina-db it has free version for sql server
.rpm and .deb
serial id will be sent by email after registration

If you use eclipse you can install Data Tools Platform plugin on it and use it for every DB engines including MS SQLServer. It just needs to get JDBC driver for that DB engine.
There is a nice CLI based tool for accessing MSSQL databases now.
It's called mssql-cli and it's a bit similar to postgres' psql.
Install for example via pip (global installation, for a local one omit the sudo part):
sudo pip install mssql-cli
