Doskey works in modern versions of Windows for setting aliases for single commands, e.g. doskey foo=bar.

There's a slight problem trying to use it for compound commands like doskey foo=bar & baz since this gets interpreted as (doskey foo=bar) & baz. The obvious fix would be to add explicit parentheses, doskey foo=(bar & baz) but for some reason this doesn't work, and doskey foo="bar & baz" doesn't work either.

Is there any way of doing this?

Escape the ampersand.

foo=bar ^& baz

Use $T to separate commands:

doskey foo=bar $T baz
doskey cpdel=copy $1 $2 $T del $1

from doskey /?:

$T     Command separator.  Allows multiple commands in a macro.

to add to the previous answers, you can also do this:

mybatfile.cmd

    doskey /macrofile=aliases.txt

aliases.txt

    foo=bar & baz
    cpdel=copy $1 $2 $T del $1
    cc=echo|set /p=$*|clip

note that in the macrofile, there is no need to escape pipe/ampersand and you can define multiple aliases in one call.

To (somewhat) add on to Dennis Williamson's answer, you can also escape the pipe character in order to pipe commands! For example, I wanted a command that copies stuff to the clipboard. Due to the way COPY will interpret it, you need to do a goofy looking command for it to actually copy the text you specify without it being followed by a newline.

In order to define a macro for copying to the clipboard, you can escape the pipe with ^:

doskey cc=echo^|set /p=$*^|clip

Upon execution of the command cc hey, you will now have hey copied to the clipboard!

  • I was also wondering how to prevent the copy of the newline character! Thanks. – Alex Vallejo Jan 30 '18 at 1:44
