#awk

I am in urgent job search mode, so I'm gonna throw this out here and see if anything comes of it.

I am a #Canadian, fluent in both #English and #French. I have experience with several programming languages. My strongest proficiency is with #Haskell and #C. I also have a reasonable grasp of #HTML, #JavaScript, #SQL, #Python, #Lua, #Linux system administration, #bash scripting, #Perl, #AWK, some #Lisp (common, scheme, and emacs), and probably several others I've forgotten to mention.

I am not necessarily looking for something in tech. I just need something stable. I have done everything from software development, to customer support, to factory work, though my current circumstances make in-person work more difficult than remote work. I have been regarded as a hard worker in every job I have ever held.

I found a bug in my #awk AI bot that ended up blacklisting to many IPs. Because of a variable I thought would be initialized but turned out to be containing a previous value. I fear that this makes me a developer. A poor one, but one still.

For me, it was during a lull in my workload at the #IBM Hursley lab in the UK when I worked my way through the O'Reilly #sed & #awk book (the one with the two lorises on the cover).

I'm guessing it was 1995 because my annual birdwatching summary at the start of the next year switched from a fixed column text document to formatting in #Postscript. My first big awk project was to process the underlying data to generate a PS document (something I also learned in the same downtime period).

Front cover of the O'Reilly programming book for the sed and awk text processing tools. The cover has the title in white on a magenta background and woodcut illustrations of two slender lorises.
Page of my birdwatching notebook. The species list would have been printed at the start of the 1995 and notes on the right represent dates in that year when I saw species in question (others are from earlier years or ones I did not bother specially to note on this page when I saw them that year). This list was generated from another long-lost file that was a (fixed-column) log of significant obserations. From that, I used to generate this summary with columns for each country in which I had watched birds. The first column of letters includes A for species seen in the UK, B for ones seen in the western palaearctic an C for others. The page shows a list of birds from (Green-winged) Teal to Sora with common and scientific names and the country letter columns all in a fixed-width font (Courier?). There are some dates to the right entered using a ballpoint pen.
Page of my birdwatching notebook for 1996. This species list would have been printed at the start of that year. The information content is similar to the year before, but everything is laid out in a grid with a variable width font and stylised X symbols in place of the letters from the year before. This version was created by generating multi-page Postscript from plain text using awk.

Doing some table generation in awk, and is there an easier way to do "all fields n to NF" than this?

function combine(combn, combs) {
for (; combn<=NF; ++combn) {
combs=combs "\t" $(combn)
}
return combs
}

I could use printf on the fragments, but the annoyance is that loop, instead of
(string-join (cddr fields) "\t")
or whatever.

Ich habe hier 200 Text-Dateien, jeweils ca. 110 Megabyte, über 1,6 Millionen Zeilen.

Die erste Spalte soll fortlaufende Zahlen enthalten.

for F in $(ls stream_*.txt); do echo -en "$F\t"; awk 'NR==1{n=$1-1;}{print $1-NR-n;}' $F | uniq -c; done

Schleife über alle Dateien mit Namen stream_*.txt:
– gib Dateinamen aus,
– ziehe Zeilennummer und (ersterWert-1) von erster Spalte ab,
– zähle, wie häufig "0" oder etwas anderes rauskommt.

Ergebnis: alles in Ordnung ✅ 🥳

Der #FPGA lief gut durch, ∃ Logdatei mit 29.385.185 Zeilen.

Die erste Spalte soll einfach nur hochzählen (wenn Zahlen fehlen = Fehler).

awk '{print $1-NR;}' tomotrg25.log | sort -n | uniq -c

… zieht von der Zahl in der ersten Spalte ($1) die Zeilennummer (NR = number of records) ab, dann wird sortiert, dann werden identische Zeilen zusammengefasst/gezählt.

Weil die Werte tatsächlich aufsteigend sind: $1-NR = const und diese Konstante kommt 29385185 mal vor 🥳

If you want to run a #Linux command, displaying only the header line and lines which match a pattern, you can turn to #awk

Example:

sudo ss -tlunp | awk 'NR == 1 { print; } /dnsmasq/ { print; }' | less -NSiRJ
