bash - Passing unescaped equals sign to GNU parallel in args -

-

i invoked gnu parallel (on os x yosemite, installed using macports, shell bash 3.2.57) this:

parallel mycommand -o a=5 -o ::: y=1 y=2

with intent run following commands, in parallel:

mycommand -o a=5 -o y=1 mycommand -o a=5 -o y=2

but runs this:

mycommand -o a=5 -o y\=1 mycommand -o a=5 -o y\=2

the backslash causes mycommand not recognize argument. problem. , after scanning man page , reading section of tutorial on quoting, can't figure out way parallel run commands without backslash getting in there. i've tried putting y= options in file, i've tried single , double quotes various levels of nesting, output of parallel --dry-run shows y\=. there way can backslash out?

this should trick:

parallel eval mycommand -o a=5 -o ::: y=1 y=2
