Sample Output
1 sheep, 2 sheep, 3 sheep, ...

  • Adjust "sleep X" to your needs. *NOTE: First sleep is required because bash doesn't have a "post-test" syntax (do XXX while). Show Sample Output


    3
    dd if=/path/to/inputfile of=/path/to/outputfile & pid=$! && sleep X && while kill -USR1 $pid; do sleep X; done

  • the block of the loop is useful whenever you have huge junks of similar jobs, e.g., convert high res images to thumbnails, and make usage out of all the SMP power on your compute box without flooding the system. note: c is used as counter and the random sleep r=`echo $RANDOM%5 |bc`; echo "sleep $r"; sleep $r is just used as a dummy command. Show Sample Output


    5
    c=0; n=8; while true; do r=`echo $RANDOM%5 |bc`; echo "sleep $r"; sleep $r& 2>&1 >/dev/null && ((c++)); [ `echo "$c%$n" | bc` -eq 0 ] && echo "$c waiting" && wait; done

  • The '[r]' is to avoid grep from grepping itself. (interchange 'r' by the appropriate letter) Here is an example that I use a lot (as root or halt will not work): while (ps -ef | grep [w]get); do sleep 10; done; sleep 60; halt I add the 'sleep 60' command just in case something went wrong; so that I have time to cancel. Very useful if you are going to bed while downloading something and do not want your computer running all night.

  • Enable 'sleep' function in Windows environment where this does not exist, although not exact in time. (there is a delay for each ping) This is a simple way to separate commands with a time-period. Show Sample Output


    -2
    echo sleep() begins: %TIME% && FOR /l %a IN (10,-1,1) do (ECHO 1 >NUL %as&ping -n 2 -w 1 127.0.0.1>NUL) && echo sleep() end: %TIME%

Why you need for loop? echo {1..199}"sheep" | xargs -n1 say
