(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 characters e r r o r l e v e l , including the space (and also CR and LF). So what’s the point?

(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)

@Ghost_Dz: (1) It appears from the question that the OP wants to write the twelve graphical characters % e r r o r l e v e l % to the file. Your suggestion writes only the ten graphical characters e r r o r l e v e l. The question also shows that the OP knows that echo something > filename will write something to the file, so if they had wanted to write the ten graphical characters e r r o r l e v e l, they would have known enough to do echo errorlevel > error.txt. … (Cont’d)

| Mar 2, 2022 at 21:30 | comment | added | Ricardo Bohner | @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.... | |

Actually it writes %...% space CR LF. Another way to avoid the space (but not the CR LF) is echo>error.txt %%errorlevel%% but I don't claim beauty.

Added generic warning about `echo something > somefile`.
