Hi guys. With the latest version of 'parallel' from EPEL? - absolutely one of the coolest binaries ever - I wonder if you noticed this: I'm doing this as 'root', with no particular reason: -> $ > ~/1 -> $ parallel --tag --nonall -S boxA,boxB uptime -> $ cp /etc/shadow ~/1 -> $ parallel --tag --nonall -S boxA,boxB uptime one of the boXes has that 1 file. (previous parallel version do not do that) and if you happened to be a code-wizz, then you wondered & can tell what the source is doing & why. (is it bash/shell?) many thanks, L.
