Dear Root users, i’m in trouble right now. I built a .C program and I want it to write all its outputs in a .log file. I’m now using the last version of Root (6.10), but the command .> does not work.
The terminal, in fact, stucks like in the image and the output file gets some weird symbols. i tried to combine it in many ways, like the following but it does not work.
root [1] .> output.log .x myfile.c("inputfile.txt")
root [1] .x myfile.c("inputfile.txt") .> output.log
root [1] .> output.log
.x myfile.c("inputfile.txt")
and so on…

Don’t know what this means, but I tried to copy your sequence of commands and it gave me this.

I just printed one of my histogram to generate an output … Just do:
root [0] .> filename
... some root command generating output ...
.>
then you are back to the root prompt and the file filename
contains the output.
