pct calculates the distribution of lines in text. It is similar to sort | uniq -c | sort -n -r, except that it prints percentages as well as counts.
Sample output:
$ cat std.qc | grep "clearfat" | pct | head
33.05% 1204 clearfat q=2 c=0
18.80% 685 clearfat q=4 c=0
17.76% 647 clearfat q=3 c=0
4.47% 163 clearfat q=6 c=0
3.90% 142 clearfat q=8 c=0
3.84% 140 clearfat q=10 c=0
2.72% 99 clearfat q=5 c=0
1.95% 71 clearfat q=13 c=0
1.73% 63 clearfat q=4 c=4
1.40% 51 clearfat q=7 c=0I originally wrote it for compiler investigations, but have found it to be broadly useful.
This kind of tool seems to be prone to convergent evolution: https://blog.mozilla.org/nnethercote/2018/07/24/ad-hoc-profiling/
