I need to run a series of program execution simulations both on MIPS and ARM processors, for that I'm using a benchmark called MPSoCBench. In total there will be over 200 simulations, so I created a bash script to execute it one by one and save the output to a file. However, for some reason, it is not redirecting the output like it should be.

Here is the bash script:

source env.sh
echo "Simulation start"
./MPSoCBench -p=mips -s=stringsearch -i=noc.lt -n=1 -r > output/MIPS/stringsearch/stringsearch-1.out
./MPSoCBench -p=mips -s=stringsearch -i=noc.lt -n=2 -r > output/MIPS/stringsearch/stringsearch-2.out

echo "Simulation end"

So for example, if I run: ./MPSoCBench -p=mips -s=susansmoothing -i=noc.lt -n=1 -r

the terminal output is:

[['mips'], ['1'], ['susansmoothing'], ['noc.lt']]
./platform.noc.lt.x susansmoothing.mips.x 1

If I try to redirect this output to a file with the command: ./MPSoCBench -p=mips -s=susansmoothing -i=noc.lt -n=1 -r > output/MIPS/susansmoothing/susansmoothing-1

Then some weird stuff happen, first there is still terminal output:

[['mips'], ['1'], ['susansmoothing'], ['noc.lt']]

It is like some lines are redirected and other are not, what is going on here? Perhaps multi-threading? If so, how can I wait for the program to finish executing and then copy the terminal output to a file?

Thank you.

    You might not be piping output on stderr. Try using &> instead of > (Bash 4+). Commented May 28, 2018 at 22:56
  • It's not about the stderr, I just tried it and the output was the same. Perhaps it has something to do with multi-threading. Commented May 28, 2018 at 23:01
  • For some reason the solution proposed by Tripp didn't work, but using &> did, @hnefatl can you post it as an answer? Commented May 28, 2018 at 23:06

    As an aside, this looks like you would need to find out about for p in ARM MIPS; for s in stringsearch dijkstra sha ...etc; do for n in 1 2 3 4; do ./MPSoCBench -p="$p" -s="$s" -i=noc.lt -n="$n" -r > "output/$p/$s/$s-$n.out; done; done; done Commented May 29, 2018 at 4:14

The program output appears to be on STDERR instead of STDOUT. Give this a try:

./MPSoCBench -p=mips -s=dijkstra -i=noc.lt -n=2 -r > output/MIPS/dijkstra/dijkstra-2.out

changes to

./MPSoCBench -p=mips -s=dijkstra -i=noc.lt -n=2 -r > output/MIPS/dijkstra/dijkstra-2.out 2>&1

Note the 2>&1 added after the redirect. It sends STDERR -> STDOUT.
