I see what you are saying. We can probably make a wrapper as a crappy
workaround. But --joblog, {#} and a lot of other details will be
wrong.
So here is a 10 minutes crappy wrapper:
#!/bin/bash
parpar() {
. `which env_parallel.bash`
env_parallel --session
inner() {
parallel "${command[@]}"
}
export -f inner
command=()
while [[ $# -gt 0 ]]; do
if [[ $1 == ",,," ]] ; then
break
fi
command+=("$1")
shift
done
printf "%s\n" "$@" |
env_parallel --pipe --recend ',,,\n' --rrs -j1 -N1 inner
}
# Example (,,, = wait for completion)
parpar -v sleep {}\; echo {} ,,, 3.9 4 4.1 ,,, 1 2 3 ,,, 0.2 0.3 0.1
