Is there an easy way to do that, or do we
have to use a char map or tempfile for that.

I started a thread on this very subject a while ago:
Sort tokens within a string & Disable FOR /F EOL optionMy first solution in the initial post I still like, but it has limitations with * and ?
The 1st response by amel27 has 2 great solutions, one a variant on my solution that eliminates the wildcard limitation, and then a 2nd that I thought was very novel that has a limitation with =.

I also like your first solution, I don't think I'll be needing the second solution for now.
I would have never figured that out, as sort does not sort outside of a for.
This makes me wonder how you found out.
because echo. C, B, A |sort simply gives >C, B, A.
I also don't understand why leaving out @ on echo suddenly shows the path, why is that ?
Code: Select all
for /f %%a in ('^(for /f %%t in ^(!str!^) do @echo %%t^)^|sort %~2') do set "sorted=!sorted! %%a"
I created a macro on it:
Code: Select all
for /f %%? in ( %$n1c%
'^^^^^( for %%? in ^^^^^(^^^!$str^^^!^^^^^) do @echo %%?^^^^^)^^^^^|sort' %$n1c%
) do set "$sorted=^!$sorted^! %%?" %$n1c%
Thanx.

I don't understand why, but somehow the DO commands are echoed if the entire FOR loop is within a block (parentheses), and the block is on the left of a pipe.
Code: Select all
@echo off
(for %%t in (c b a) do echo %%t)|more
output:
Both of the following fix the problem:
Code: Select all
@echo off
(for %%t in (c b a) do @echo %%t)|more
Code: Select all
@echo off
(echo off & for %%t in (c b a) do @echo %%t)|more

Maybe it has to do with the fact that @echo ?)|more creates a new process and that somehow @echo is turned on or maybe it's just another bug
