Hello!
I am pleased to announce a new version of my CLI text processing with GNU awk ebook. Learn this handy tool with hundreds of examples and exercises.
To celebrate the new release, you can download the PDF/EPUB versions for free till 06-April-2025:
* https://learnbyexample.gumroad.com/l/gnu_awk
* https://leanpub.com/gnu_awk/c/free
Or, you can read it online at https://learnbyexample.github.io/learn_gnuawk/
Happy learning :)
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.
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 
# contexto : Mostrar gráfico después de procesamiento de contactos
# objetivo : Nube de números telefónicos +58
# proceso : Archivo contactos fue filtrado con awk
# salida : Nube de números telefónicos
# Hay números repetidos
#Lecheria #ANZ #Anzoategui #Costarica #Contactos #AWK #Creatividad #Rstats #Nube
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

you for life. The fastest and plainest way of crunching massive misformatted data.

Do you find awk one-liners cryptic? Stuff like !a[$0]++, 1, $1=$1, NR==FNR and -v RS=? I wrote a blog post to explain such idioms.
... Odd that "#awk" complaints about newline in the first case

@holger grep, awk and sed. Available on pretty much every distribution. Not leaking info, either.
Honestly - steep learning curves but once you're even slightly proficient then you can find all the needles in all the haystacks you want, neatly.
Add in jq for conversion to JSON for a more transportable format.
How The 'awk' Command Made Me A 10x Engineer

Je viens d'arriver à écrire un script shell en une ligne de awk pour un projet Kirby bilingue où je dois formater des gros fichiers .txt exportés depuis un tableau de traduction sous forme de tableaux PHP indentés correctement, et ça me rend heureux :
`awk -F$'\t*' '{gsub(/[ \t]+$/,"",$1); print " \""$1 "\" => \"" $2 "\","}' input.txt`
Alors que c’est pas fou hein en soi, mais c’est tellement satisfaisant quand ça marche !
