Broken pipe

Hi all,

I am trying to run a sleep command and I am receiving a broken pipe when I execute. any help would be greatly appreciated.

sleep `< /dev/urandom tr -dc 0-6 | head -c2`

2

Try: LANG=C tr -dc 0-6 instead of tr -dc 0-6

/dev/urandom produces binary number, not human readable numbers

try:

sleep $( $RANDOM | tr -dc '[0-6]' )

A better approach is to use modulo arithmetic, say you want random values from 1 to 10:

sleep $((  ($RANDOM %10)  + 1 ))
