[ale] how do I - icon starts script starts 4 scripts



to add a delay, use sleep n where n is a number seconds to pause. You can
use different units from seconds. Man sleep will give a bit more detail.

For fun, you can do a loop in the master script that that just calls the
launch script (same one) over and over and that pulls a conf string based
on the param passed

master:

#!/bin/bash  (I always spec /bin/bash so it won't fubar under a reset link
to csh or <shudder>zsh)
# master script
MINNING=<path to mining script>  (this is chmod +x)
miners=4
for i in $(seq 1 ${miners})
do
  ${MINNING} ${i}
done
tail -f <path to logs>/miner*.log


---------------------------


The MINNING script is generically:
#!/bin/bash
# this runs the actual minning process

which_one=$1

case $which_one in
  1)       graphics_param='string of crap for card 1'
            log_file='path to output log/miner'${which_one}'.log'
            ;;
  2)       graphics_param="second string of graphics crap'
            log_file.....
            ;;
...
esac

# Now run the script with all the params

<miner binary name> ${graphics_param} ${log_file} &

return 0

------------------------------

So if you get more graphics cards, edit the script and add a new case line
and edit the master and up the counter.
