Root does not redirect command to a given file

[taragno]

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.

Thank you for the help. Now the program prints the output correctly.
