Not sure if this can be achieved by unix , but still would like to know if there is any way by which I can do the below given logic
cat sam1 > out1
cat sam2 > out2
when either one of this finished the the next file shd be written in that file, meaning
cat sam3 >> out1/out2 (depending on which finishes first)
similarly cat sam4 >> out1/out2
Please tell me if its possible, if yes would be really helpful If you could give me a slight heads up on how to do it
I presume you mean, whenever sam1 finishes, read from it? Will sam2 exist before sam1 finishes? If not, you can use that to detect when the files finish:
Code:
FILE=1
NEXTFILE=`expr $FILE + 1`
while true
do
# If the next file doesn't exist, sleep a bit, and go back to top of loop
if [ ! -e sam"$NEXTFILE" ]
then
sleep 1
continue
fi
# Print message ( to stderr, so it doesn't end up in outputfile )
echo "Reading from sam$FILE" >&2
# Read from current file
cat sam"$FILE"
# Set up for next file
FILE="$NEXTFILE"
NEXTFILE=`expr $FILE + 1`
# All output gets written to outputfile
done > outputfile
Of course, the smart thing to do would be to not split it in the first place, and use the output direct...

You can enumerate the files into the loop and employ two background processes, one writing to out1 and the other to out2. Using the jobs command you can check whether one of them has finished and then you can read the next filename and you can start a new job that cats the contents new filename to out1 or out2 depending on which job had finished.....
