I have a log file containing a stack trace split over a number of lines. I need to read this file into a batch file and remove all of the lines breaks.
As a first step, I tried this:
if exist "%log_dir%\Log.log" (
for /F "tokens=*" %%a in ("%log_dir%\Log.log") do @echo %%a
)
My expectation was that this would echo out each line of the log file. I was then planning to concatenate these lines together and set that value in a variable.
However, this code doesn't do what I would expect. I have tried changing the value of the options for delims and tokens, but the only output I can get is the absolute path to the log file and nothing from the contents of this file.
How can I set a variable to be equal to the lines of text in a file with the line breaks removed?
