I am trying to use a loop to start tasks 0-3, running 0,1,2 in the background with &.
Code:
FOLDSET=( 0 1 2 3 )
for FOLDSET in ${FOLDSET[@]}
do
if [ $FOLDSET -lt 3 ]; then
BACKGRD="&"
else
BACKGRD=""
fi
# start task $FOLDSET
task1 -nogui -ni -p $PROJ \
epochs=$EPOS batches=$BATCH n_threads=$THRD \
arch=$ARCH data_set=$DSET fldTag=f$FOLDSET $BACKGRD
done
I am truing to append & to the first three task (0,1,2), but not have & after the 4th. This will pause the script after task 4 and wait for it to finish before moving on. This is not working. I have tried & with and without the quotes with no difference. The code starts a four tasks, but in sequence instead of simultaneously.
Any suggestions, or am I going about this all wrong.

$BACKGRD has the value of "&" for the first three time through the loop, but apparently that doesn't work.
I can probably do this like ,
Code:
FOLDSET=( 0 1 2 3 )
for FOLDSET in ${FOLDSET[@]}
do
if [ $FOLDSET -lt 3 ]; then
# start the first three in the background
task1 -nogui -ni -p $PROJ \
epochs=$EPOS batches=$BATCH n_threads=$THRD \
arch=$ARCH data_set=$DSET fldTag=f$FOLDSET &
else
# wait on the last one
task1 -nogui -ni -p $PROJ \
epochs=$EPOS batches=$BATCH n_threads=$THRD \
arch=$ARCH data_set=$DSET fldTag=f$FOLDSET
fi
done
unless there are other/better suggestions.
