Hi,

Is there an equivalent DOS command for UNIX "uniq" command? Or maybe several
DOS commands have to be used together to achieve the same?

Not built-in but UnxUtils which offer many Unix-like tools for
Win32 is worth having.
http://unxutils.sourceforge.net/

However they have messed up their download page and you have to
hunt for someone else (reliable) offering them:

Google: [ unxutils GNU win32 ]

FTHOI, you could always roll your own using WSH/VBScript. Put the
following into a file named uniq.vbs.

'-- begin uniq.vbs ----
Dim tr, pr

pr = -1

With WScript
Do
tr = WScript.StdIn.ReadLine
If tr <> pr Then WScript.StdOut.WriteLine tr
pr = tr
Loop Until WScript.StdIn.AtEndOfStream
End With
'-- end uniq.vbs ----

Then use it in a command line like

cscript //nologo uniq.vbs < yourinputfile > youroutputfile
 
the following bat script (say uniq.bat) does the job:

set previousLine=
for /f "tokens=* delims= " %%l in (%*) do (
if not %%l == !previousLine! (
echo %%l
)
set previousLine=%%l
)

then: uniq[.bat] file.txt. for it to work the command window must be started with delayed variable interpretation, i.e. cmd.exe /v:on.
