On intel platform, thermobench can not read

/sys/devices/virtual/powercap/intel-rapl/intel-rapl\:0/intel-rapl\:0\:0/energy_uj

gives error?

thermobench: Error while opening sensor file: /sys/devices/virtual/powercap/intel-rapl/intel-rapl\:0/intel-rapl\:0\:0/energy_uj: No such file or directory

following command returns its contents just fine

 cat  /sys/devices/virtual/powercap/intel-rapl/intel-rapl\:0/intel-rapl\:0\:0/energy_uj

Just remove the backslashes. They are not a part of file name. See:

cat  /sys/devices/virtual/powercap/intel-rapl/intel-rapl:0/intel-rapl:0:0/energy_uj

Shell replaces \X with X even if X has special meaning for shell (space, $, ...). Colon does not have special meaning for most shells so it's not necessary to use \: instead of :.
