runj v0.1
Run a command with multiple processes.
Example
Try this to clean-up space on your hard drive (choose NVme for faster speed).
# cd / && find -d -print0 | runj 8 xargs -0 rm -f
This will run 8 parallel xargs -0 rm -f processes.
Try this to speed up any shell script (warning, do not try this at home or on Linux) !
runj < MyScript.sh 32 sh -cThis will run sh full speed on your 32 core server.
More seriously, I needed to speed up my test infrastructure which is shell-based and want to run commands in parallel. -1 will use all the available cores.
runj < tests -1 ./test-runnerSimple as that and MP-safe.
