- junkblocker 11y agoOops s/\//\\%/ yeah. sleep $[RANDOM\%3600]
- hjnilsson 11y agoThat will be a number between 1 and 10 ($RANDOM only goes to 32767), sleep $[RANDOM/10] would be better. :) This might be platform dependent though, I can't find any standard RAND_MAX in bash so it's difficult to make this work everywhere.
- lloeki 11y agoThis works in (da)sh (tweak 2 and 65536 if needed): sleep $(( 0x$(xxd -l2 -p /dev/random) * 3600 / 65536 ))
