How to echo with different colors in the Windows c

2018-12-31 21:27发布

I know that the color bf command sets the colors of the whole command line window but I wanted to to print one single line in a different color.

This isn't a great answer, but if you know the target workstation has Powershell you can do something like this (assuming BAT / CMD script):

CALL:ECHORED "Print me in red!"

:ECHORED
%Windir%\System32\WindowsPowerShell\v1.0\Powershell.exe write-host -foregroundcolor Red %1
goto:eof

Edit: (now simpler!)

It's an old answer but I figured I'd clarify & simplify a bit

PowerShell is now included in all versions of Windows since 7. Therefore the syntax for this answer can be shortened to a simpler form:

  • the path doesn't need to be specified since it should be in the environment variable already.
  • unambiguous commands can be abbreviated. For example you can:
    • use -fore instead of -foregroundcolor
    • use -back instead of -backgroundcolor
  • the command can also basically be used 'inline' in place of echo
    (rather than creating a separate batch file as above).

Example:

powershell write-host -fore Cyan This is Cyan text
powershell write-host -back Red This is Red background

More Information:

The complete list of colors and more information is available in the
- PowerShell Documentation for Write-Host

You'll need to echo an ANSI escape code sequence to alter the text colour: http://en.wikipedia.org/wiki/ANSI_escape_code

Another very good source of these escape codes is http://ascii-table.com/ansi-escape-sequences.php

This is a self-compiled bat/.net hybrid (should be saved as .BAT) that can be used on any system that have installed .net framework (it's a rare thing to see an windows without .NET framework even for the oldest XP/2003 installations) . It uses jscript.net compiler to create an exe capable to print strings with different background/foreground color only for the current line.

@if (@X)==(@Y) @end /* JScript comment
@echo off
setlocal

for /f "tokens=* delims=" %%v in ('dir /b /s /a:-d  /o:-n "%SystemRoot%\Microsoft.NET\Framework\*jsc.exe"') do (
   set "jsc=%%v"
)

if not exist "%~n0.exe" (
    "%jsc%" /nologo /out:"%~n0.exe" "%~dpsfnx0"
)

%~n0.exe %*

endlocal & exit /b %errorlevel%

I was annoyed by the lack of proper coloring in cmd too, so I went ahead and created cmdcolor. It's just an stdout proxy, which looks for a limited set of ANSI/VT100 control sequences (in other words, like in bash), i.e. echo \033[31m RED \033[0m DEFAULT | cmdcolor.exe.

Usage and downloads.

you could use cecho.. you can also use it to embed right into your script so you dont have to carry along a .com or .exe
