hello,
far from being a power user with linux...
... i happen to play with parallel...
and get confused/surprised at times. Like so:
echo this should not happen | xargs -n 1 echo | parallel --dry-run -n 2
echo `echo {}`
First, i was not able to separate the 4 words into different arguments
with --colsep ' ', so that is why i used xargs in the mix.
Then, i did not expect --dry-run to allow for execution of the embedded
`echo` command.
Ok, i can imagine scenarios, when this comes in handily...
My current conclusion is: be VERY careful with this powerful tool, test
thoroughly before execution but even then... (can i trust it?) beware of
unexpected side-effects.
just my 2 cents
