Hi,

it's a terrible slow bash script that delays opening a terminal, so
taking a look at what neofetch does...

[rocketmouse at archlinux ~]$ grep system/cpu/ /usr/bin/neofetch 
# NOTE: Any file in '/sys/devices/system/cpu/cpu0/cpufreq' can be used as a value.
            speed_dir="/sys/devices/system/cpu/cpu0/cpufreq"

...and just adding the important part to .bashrc...

[rocketmouse at archlinux ~]$ head -13 ~/.bashrc
#
# /home/rocketmouse/.bashrc
#

# If not running interactively, don't do anything
[[ $- != *i* ]] && return

PS1='[\u@\h \W]\$ '
#PS1='[\u@\h \w]\$ '

#(neofetch)
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq | awk '{print int($1/1000) "MHz"}'

...IMO is way more comfortable. More useful might be to add nothing at
all to .bashrc and instead to launch...

[rocketmouse at archlinux ~]$ watch -n 1 cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

...to monitor the speed in Hz.

Ralf
