I have to store the ouput of DIR in a variable.
This was asked before e.g. here or here or here.
They all provide an answer more or less similar to what I'm using right now:
%= Find the *.sln file and write its path to the file temp.temp =%
DIR /s/b *.sln > temp.temp
%= Read out the content of temp.temp again to a variable =%
SET /p texte=< temp.temp
%= Remove the temp.temp file =%
DEL temp.temp
%= Get only the filename without path =%
FOR %%A IN ("%texte%") DO (
SET Name=%%~nxA
)
But in my case I'm sure that the ouput of DIR /s/b *.sln will allways be a one-liner. To me it looks a bit ugly to have to
a) store the ouput in an external file and
b) run a FOR loop over it though I already know it will only have one line.
Is there any direct/simpler way to do this?

Output: The > operator is used to overwrite any file that already exists with new content. The >> operator is used to append to the text file (add to), instead of overwriting it.
When used in a command line, script, or batch file, %1 is used to represent a variable or matched string. For example, in a Microsoft batch file, %1 can print what is entered after the batch file name.
&& runs the second command on the line when the first command comes back successfully (i.e. errorlevel == 0 ). The opposite of && is || , which runs the second command when the first command is unsuccessful (i.e. errorlevel != 0 ).
If you don't want to output to a temp file and then read into a variable, this code stores result of command direct into a variable: If you want to store this code in a batch file, add an extra % symbol: A useful example to count the number of files in a directory & store in a variable: (illustrates piping)
Notes 'bout the code: the output from the command executed via call :EXEC command is stored in %output%. Batch cmd doesn't cares about scopes so %output% will be also available in the main script. the @ the beginning is just decoration and there to suppress echoing the command line.
The only difference between the two answers above is that on the command line, you use a single % in your variable. In a batch file, you have to double up on the percentage signs (%%).
Boils down to: You can also redirect the output of a command to a temporary file, and then put the contents of that temporary file into your variable, likesuchashereby. It doesn't work with multiline input though.
for /f "delims=" %%a in ('dir /s /b *.sln') do set "name=%%a"
indeed is the most efficient method (you can process the output of a command directly, no need for a temporary file).%name% will contain the full qualified file name of your file (or the last of the files, if there are more than one)
