I want to do something like:
echo %errorlevel% > error.txt
which would save in error.txt:
%errorlevel%

If you actually want to write the twelve characters
% e r r o r l e v e l %
(as opposed to writing the numeric error level), use the command
echo %%errorlevel%%
Redirection works as normal.
However, note that
echo %%errorlevel%% > error.txt
will actually write the thirteen characters
% e r r o r l e v e l % ,
including the space (from before the >).
“Obviously” you can fix that by saying
echo %%errorlevel%%> error.txt
(leaving out the space before the >),
but this is regarded as unaesthetic and hard to read.
Another way, that might be considered to be “prettier”, is
(echo %%errorlevel%%) > error.txt

1In case you had DelayedExpansion enabled and would like to save !errorlevel! it would be something like echo ^^!errorlevel^^!>error.txt Commented Mar 2, 2022 at 16:34

1@iTwasnTme >error.txt echo ^!!errorlevel^!! saves the error number but I think we are talking about saving the word errorlevel with percentage or exclamation marks here.... Commented Mar 2, 2022 at 21:30

1@Ghost_Dz: (1) It appears from the question that the OP wants to write the twelve graphical characters
%errorlevel%to the file. Your suggestion writes only the ten graphical characterserrorlevel. The question also shows that the OP knows thatecho something > filenamewill writesomethingto the file, so if they had wanted to write the ten graphical characterserrorlevel, they would have known enough to doecho errorlevel > error.txt. … (Cont’d) Commented Mar 5, 2022 at 22:09 -
1(Cont’d) … So why do you believe that your suggestion is relevant or useful? (2) The whole point of my suggestion with the parentheses is to allow a somewhat-aesthetic (i.e., “pretty”-looking) command — with spaces before and after the
>— that doesn’t silently write a space to the file. (Users of English — and remember that English is the official language of Stack Exchange — are accustomed to seeing graphical characters immediately after(and before), with no intervening space. … (Cont’d) Commented Mar 5, 2022 at 22:09 -
1(Cont’d) … But when you see
%>, with no intervening space, it’s less obvious that they are parts of two separate tokens.) But, since you included a space before the)in your command, it writes the eleven printable characterserrorlevel , including the space (and also CR and LF). So what’s the point?
