Booksonline and google are great resources, but if you need an example, here's both an out and in in:

--using a super special 4 char row delimiter to be sure it doesn't exist in the data

--flags explanation:

-- -c = charcater data

-- -t"[||]" = field terminator

-- -r"[~~]" = row terminator

-- -T' = Trusted connection

--out

EXECUTE master.dbo.xp_cmdshell 'bcp "SELECT EMAILTEMPLATESID, EMAILBODY FROM Sandbox.dbo.EMAILTEMPLATES ORDER BY EMAILTEMPLATESID" queryout c:\Data\bcpExample.txt -c -t"[||]" -r"[~~]" -T'

--in

EXECUTE master.dbo.xp_cmdshell 'bcp Sandbox.dbo.EMAILTEMPLATES in c:\Data\bcpExample.txt -c -t"[||]" -r"[~~]" -T'

--in via bulk insert

BULK INSERT EMAILTEMPLATES FROM 'c:\Data\bcpExample.txt'

WITH (

DATAFILETYPE = 'char',

FIELDTERMINATOR = '[||]',

ROWTERMINATOR = '[~~]',

FIRSTROW = 1

)
