I was going to say: ls *.png *.jpg etc |shuf |sed q
But I don't /have/ shuf here. I wonder where it came from on my home
machine... GNU coreutils it seems, must have a newer version at home.
Anyway, shuf is not on my netbsd machine either so I wrote this naive
replacement:
#!/bin/sh
awk '
BEGIN {srand()}
{l[NR]=$0}
END {
while(length(l)) {
i=int(rand()*NR+1)
if(i in l) {
print l[i]
delete l[i]
}
}
}'
-sqweek
