Title: Live in a terminal
Post by: qinohe on September 25, 2018, 07:14:34 pm

Hello OPNsensers,

I'm (very) curious of other users scripts and shell adaptions
With that I mean: do you tweak your shell, what does your .cshrc.mine look like, did you add some useful code/script to OPNsense?
I could find a BSD forum and ditch it there, but that don't seem right and besides that OPNsense is my only BSD ATM.
So moderators, I hope this is allowed and we can share some shell/scripting code for OPNsense here?, this could have some value for all of us, thanks.
If you decide to join in and add scripts, please, rather add SH code than BASH, I have it installed but most of us don't, thanks.

Let me do the kickoff right away  :P

My .cshrch.mine

Code: [Select]

# $FreeBSD$
#
# .cshrc.mine - csh resource script, read at beginning of execution by each she
ll
#
# see also csh(1), environ(7).
# more examples available at /usr/share/examples/csh/
#
# few aliases I like to have
#alias sum       'cksum /usr/local/share/certs/ca-root-nss.crt | sort | diff sum.txt -'
alias tm        tmux attach
alias vim       vi

# Tab completion and - correction
if ($?prompt) then
        set autocorrect =       ambiguous
        set complete    =       enhance
        set correct     =       cmd
endif

# some extra program completions
complete sysctl 'n/*/`sysctl -Na`/'
complete man 'p,*,c,'

# BSD is functional but pretty colorless, let's change that

# Let 'ls' have some color
setenv CLICOLOR yes

# Basic colors
set     red="%{\033[1;31m%}"
set   green="%{\033[0;32m%}"
set    blue="%{\033[1;34m%}"
set  yellow="%{\033[1;33m%}"
set magenta="%{\033[1;35m%}"
set    cyan="%{\033[1;36m%}"
set   white="%{\033[0;37m%}"
set     end="%{\033[0m%}"

# Colored prompt
set prompt="${cyan}%n${red}@%m ${white}%~ ${cyan}%%${end} "

# Colored man pages, I dislike the undelining of everything..
setenv LESS_TERMCAP_mb `echotc md; echotc AF 4`
setenv LESS_TERMCAP_md `echotc md; echotc AF 4`
setenv LESS_TERMCAP_me `echotc me`
setenv LESS_TERMCAP_se `echotc me`
setenv LESS_TERMCAP_so `echotc md; echotc AF 1; echotc AB 4`
setenv LESS_TERMCAP_ue `echotc me`
setenv LESS_TERMCAP_us `echotc md; echotc AF 2`

# Unset used colors
unset red green blue yellow magenta cyan white end

My .tmux.conf

Code: [Select]

set -g default-terminal "screen-256color"

# interval is up to you, but it may use precious cpu time if set to 1
set-option -g status-interval 30
set-option -g status-right-length 60
set-option -g status-left-length 120

set -g status-bg colour237
set -g status-fg colour237
set -g mouse on

set -g status-left '#[fg=blue] #(hostname -s) #[fg=colour41]*#[fg=blue] #(sh bin/tmx temp)C #[fg=colour41]* #[fg=blue]#(sh bin/tmx mem) #[fg=colour41]* #[fg=blue]#(sh bin/tmx sum)  '
set -g status-right '#[fg=blue]#(sh bin/tmx avg)#[fg=colour41]* #[fg=blue]%H:%M'

# Attach a running session or create a fresh one
new-session -n $HOST

Script called by tmux, I use it for the statusbar,

Code: [Select]

#!/bin/sh
set -xe

temp () {
  var1=$(sysctl -n dev.cpu.0.temperature | awk '{printf "%3.0f\n",$1}')
  var2=$(sysctl -n dev.cpu.1.temperature | awk '{printf "%3.0f\n",$1}')

  echo "scale=1; ($var1 + $var2) / 2" | bc
}

mem () {
  mem_real=$(sysctl -n hw.realmem)
  pagesize=$(sysctl -n hw.pagesize)

  inact_count=$(sysctl -n vm.stats.vm.v_inactive_count)
  free_count=$(sysctl -n vm.stats.vm.v_free_count)

  mem_inact=$(printf "%s\\n" "$inact_count *$pagesize" | bc)
  mem_free=$(printf "%s\\n" "$free_count * $pagesize" | bc)

  mem_avail=$(printf "%s\\n" "$mem_inact + $mem_free" | bc)
  mem_used=$(printf "%s\\n" "$mem_real - $mem_avail" | bc)

  printf "%s\\n" "$(("$mem_used * 100 / $mem_real"))"%
  exit 0
}

avg () {
  sysctl -n vm.loadavg | sed 's/{//g;s/}//g'
}

sum () {
  if [ "$(cksum /usr/local/share/certs/ca-root-nss.crt | \
      awk '{printf "%-1s %s\n", $1 , $2}')" \
      != "$(awk '{printf "%-1s %s\n", $1 , $2}' ~/sum.txt)" ]; then
    echo nss-mismatch
  fi
}

if [ "$1" = temp ]; then
  temp
elif [ "$1" = mem ]; then
  mem
elif [ "$1" = avg ]; then
  avg
elif [ "$1" = sum ]; then
  sum
else
  printf "Usage: sh tmx (temp mem or avg) \\n"
fi

exit 0

That's it, enjoy

Hello all,

Added a function 'sum' to the script which gives a warning 'nss-mismatch' .

It's always usable, but very handy if self-signed certificates are added, your notified by the above warning to add your certificate/s again.

Create 'sum.txt' yourself of course  :P
