One-liners I often use
This page is meant to collect one liners that I use often, it will be extended in the future.
Simple occurance statistics
This is probably my most common use of shell (without couting running simple commands):
sort | uniq -c | sort -rn
Getting all the alt descriptions in the page
I use it mostly for my Genshin pages to get count of characters mentioned.
perl -ne '/alt="([^"]+)"/ && print "$1\n"'
Get word count of a page
Extracts text in the <body> tag, removes all the tags and counts the words. Works only if there isn't tags like <style> or <script> in the body of the page.
awk '/<body[^>]*>/,/<\/body>/' | sed "s/<[^>]*>//g" | wc -w
Visualizing output of uniq -c
Some AWK magic squeezed into one line. Calculates the max width of the input data and stores in in the table. Then prints it with the bar that follows each line which length is determined from the first found number in the input line.
awk 'match($0,/([0-9]+)/,a){c=length($0);w=c>w?c:w;l[NR]=$0;m[NR]=a[1]}END{for(i in l){printf(sprintf("%%-%ds",w+1),l[i]);for(j=0;j<m[i];++j)printf("█");print ""}}'
