I need to create a graph to show number of statuses per minute for TEMP, PERM and OK. So I would like to use a line for the status (TEMP, PERM and OK), plot time on the X axis, and frequency of occurrence on the Y axis.
I installed Gnuplot only 2 days ago on my Ubuntu 20.04.4 LTS from the standard repo:
bi#green:bin$ apt list gnuplot* 2>/dev/null | grep installed
gnuplot-data/focal,focal,now 5.2.8+dfsg1-2 all [installed,automatic]
gnuplot-qt/focal,now 5.2.8+dfsg1-2 amd64 [installed,automatic]
gnuplot/focal,focal,now 5.2.8+dfsg1-2 all [installed]
and so far I haven't managed more than this,
#!/bin/bash
x=logoutcol
cat $x
gnuplot -p <<-EOF
#set ytics scale 0
#set yzeroaxis
reset
set format x "%H:%M" time
set xdata time
set yrange [0:*]
set ylabel "Occurences"
set ytics 2
#set margin at screen 0.95
binwidth=60
bin(val) = binwidth * floor(val/binwidth)
set boxwidth binwidth
set datafile separator ","
set term png
set output "$x.png"
plot "$x" using (bin(timecolumn(1,"%H%M"))):(2) smooth freq with boxes
EOF
shotwell $x.png
rm $x.png
which produces this:
Any help will be much appreciated.
I am pretty sure that there was an almost identical question here on SO, however, it seems I can't find it maybe due to my incapability of finding the right keywords for SO's search function.
The key point is the boolean expression (strcol(2) eq word(myKeys,i)) together with smooth frequency. If the value of the second column is identical to your keyword the expression results in 1, and 0 otherwise.
You don't need bins like in creating other histograms because you want a bin of 1 minute (and your time resolution is already 1 minute).
Check the following example as starting point for further optimization.

### end of script
Result:
There are loads of threads about passing a shell variable to awk, and I've figured that out easily enough, but the variable I want to pass is the column specifier variable ($1,$2 etc)
Given that the shell uses these variables as default command line argument variables as well, this is getting confusing.
In this script I'm just sorting and joining 2 files together, but in order to begin generalising the script a little, I want to be able to specify on the command line, the field in the key file that awk should be taking as its sort-specifier.
What am I doing wrong here? (I'm only just getting to grips with awk and the oneliner was adapted slightly from here.
keyfile="$1"
filetosort="$2"
field="$3"
awk -v a="$field"
paste "$keyfile" <(awk 'NR==FNR{o[FNR]=a; next} {t[$1]=$0} END{for(x=1; x<=FNR; x++){y=o[x]; print t[y]}}' $keyfile $filetosort)

When you pass awk -v a="$field", the specification of the awk variable a is only good for that single awk command. You can't expect a to be available in a completely different invocation of awk.
Thus, you need to put it in-place directly:
$ bashvar="2"
$ echo 'foo bar baz' | awk -v awkvar="$bashvar" '{print $awkvar}'
bar
Or in your case:
field=1
awk -v a="$field" '
NR==FNR {
o[FNR]=$a;
next;
}
{ t[$1] = $0 }
END {
for(x=1; x<=FNR; x++) {
y=o[x]
printf("%s\t%s\n", y, t[y])
}
}' "$keyfile" "$filetosort"
Points of note:
Our printf here is emitting both the key and the value, so there's no need to use paste to put the keyfile values back in.
$a is used to treat the awk variable a (assigned from shell variable field) as a variable name itself, and to perform an indirect reference -- thus, looking up the relevant column number.
Always, always quote your shell variables on expansion. Otherwise, you have no way of knowing how many argument to awk will be generated by the expansion of $keyfile -- it could be 0 (if there are no characters in the string not found in IFS); it could be 1, but it could also be a completely unbounded number (input file.txt would become two arguments, input and file.txt; * input * .txt would have each * replaced with a list of files).
I'm going to add this as an answer because it does resolve the question as I posed it, notwithstanding Charles' excellent advice about the (myriad) areas I was going wrong.
Altering the above code with Charles' point about the separate awk commands, I can now invoke the following (sorry yes, it's still using paste)...
#!/bin/bash
keyfile="$1"
filetosort="$2"
indexfield="$3"
paste "$keyfile" <(awk -v field="$indexfield" 'NR==FNR{o[FNR]=$field; next} {t[$1]=$0} END{for(x=1; x<=FNR; x++){y=o[x]; print t[y]}}' "$keyfile" "$filetosort")
I was missing the $ before the variable I was calling in the awk command, which is (part) of why my original code wasn't working, as well as not including the awk variable declaration in a single awk call.
Thus, bash sortandmatch.sh keyfile filetosort 3 produces the output I want:

I am stuck merging some hashes to get the results that I need.
The hashes contain a breakdown of the total price of an order, e.g. item price, taxes, & shipping, for all orders in a subscription. I'm trying to do this dynamically as not all orders charge tax, or even the same tax or shipping.
Here's what I would call the "worst case scenario" that I'm dealing with:
#First order - has charges for Canadian GST and HST
{:orderhdr_id=>17654122, :order_item_seq=>1, :order_item_amt_break_seq=>1, :order_item_break_type=>0, :local_amount=>8.16, :base_amount=>8.16, :orig_base_amount=>149, :tax_delivery=>0, :tax_active=>0}
{:orderhdr_id=>17654122, :order_item_seq=>1, :order_item_amt_break_seq=>2, :order_item_break_type=>1, :local_amount=>0.41, :base_amount=>0.41, :state=>"ON", :tax_type=>"GST", :tax_rate_category=>"STD", :orig_base_amount=>7.45, :tax_rate=>5, :tax_delivery=>0, :tax_active=>1, :tx_incl=>1}
{:orderhdr_id=>17654122, :order_item_seq=>1, :order_item_amt_break_seq=>3, :order_item_break_type=>1, :local_amount=>0.65, :base_amount=>0.65, :state=>"ON", :tax_type=>"HST", :tax_rate_category=>"STD", :orig_base_amount=>11.92, :tax_rate=>8, :tax_delivery=>0, :tax_active=>1, :tx_incl=>1}
#Second order - has only one charge for tax
{:orderhdr_id=>1815296, :order_item_seq=>1, :order_item_amt_break_seq=>1, :order_item_break_type=>0, :local_amount=>76.52, :base_amount=>76.52, :orig_base_amount=>99.95, :tax_delivery=>0, :tax_active=>0}
{:orderhdr_id=>1815296, :order_item_seq=>1, :order_item_amt_break_seq=>2, :order_item_break_type=>1, :local_amount=>4.59, :base_amount=>4.59, :orig_base_amount=>6, :tax_delivery=>0, :tax_active=>1}
#Third order - has charge for shipping
{:orderhdr_id=>6112412, :order_item_seq=>1, :order_item_amt_break_seq=>1, :order_item_break_type=>0, :local_amount=>21.34, :base_amount=>21.34, :orig_base_amount=>99.95, :tax_delivery=>0, :tax_active=>0}
{:orderhdr_id=>6112412, :order_item_seq=>1, :order_item_amt_break_seq=>2, :order_item_break_type=>2, :local_amount=>4.7, :base_amount=>4.7, :orig_base_amount=>22, :tax_delivery=>0, :tax_active=>0}
The :order_item_break_type determines what type of charge it is, item, tax, shipping.
If :order_item_break_type is 0 or 2, then subtract :base_amount from :orig_base_amount and add it to the overall total for that break type. For :order_item_break_type equals 1, I need to sum up the difference of :orig_base_amount and :base_amount, but I need to keep the different taxes separate.
So here's what I should end up with for the above orders:
:break_type = 0 | total = 242.88
:break_type = 1, :state = ON, :tax_type = GST, :tax_rate_category = STD | total = 7.04
:break_type = 1, :state = ON, :tax_type = HST, :tax_rate_category = STD | total = 11.27
:break_type = 1 | total = 1.41
:break_type = 2 | total = 17.30
I have these hashes in an array called #amounts.
I have methods like merge!, inject, shift and more going through my head, but can't put it together.
How about this? I really don't know what you are doing there, though.
#amounts = [
#First order - has charges for Canadian GST and HST
