20:39:41 KatolaZ | Evil_Bob: subtree
20:40:10 Od1n | find|xargs sha256sum| awk '{x[$1]++}'
20:40:19 Poorchop | find(sub { push @duplicates, $File::Find::name if (-e and
| $File::Find::dir =~ m/file_name/i) }, catfile($directory));
20:40:19 Od1n | find . -type f|xargs sha256sum| awk '{x[$1]++}'

20:42:48 Od1n | findd -type f|xargs stat -c%s |awk '{s+=$1}END{print s}'
20:43:17 @Evil_Bob | stat -c '%s' -t dir
20:44:30 Od1n | findd -type f|xargs stat -c%s |paste -sd+|bc

20:45:00 adc | for f in *; do printf 'q\n' | ed "$f"; done |
| awk '{ sum += $1 } END{print sum}'

20:46:57 denkiko | ls -dl --block-size=K 'dir' | some awk magic x3
4.)
- create a Frankenstein poem, by collating exactly one random line
from each of the files in the current directory
for i in *; do n=`wc -l $i | cut -d " " -f 1`; rnd=`od -An -N2 -i /dev/random`; \
tail -n +`echo "$rnd%$n+1" | bc` $i | head -1; done
20:47:02 parazyd | for i in * ; do shuf -n1 $i; done
20:47:50 Od1n | cat *|tr -s ' ' '\n'|shuf|xargs -n5
20:48:25 KatolaZ | anyone without shuf(1)?
20:48:06 KatolaZ | parazyd: well done
20:48:48 Poorchop | would've taken me too long to type up my idea
20:49:04 KatolaZ | parazyd gets 3, Od1n gets 1
20:49:10 Od1n | cat *|tr -s ' ' '\n'|sort -k2|xargs -n5
Scoreboard: Od1n 7; parazyd 6; Poorchop 1; Evil_Bob 0.5
5.)

21:12:48 Od1n | hmm .. also: 26 years of daily shell. that's help
21:14:45 Od1n | also i have to admit i cheated: one of my anwser was
| basically fixing the Evil_Bob's line
21:15:03 Od1n | i made 3 points on this: this is unfair
21:15:58 Od1n | i also had to admit i used an IA trained with pytorch to
| help me
21:16:03 Od1n | and i took steroids
21:16:33 Od1n | and i asked my son to help me: he's the one who knows
| shell
21:16:57 Od1n | (i'm more confortable with powershell in my dayjob)

21:11:28 @__20h__ | Poorchop, can I do an interview with you why the perl bros
| didn't get into the lead?
21:28:36 Poorchop | I don't know if I'm qualified to speak on behalf of the
| Perlbros __20h__
21:28:52 @__20h__ | Poorchop, but you are a perl bro?
