Hi,

I try to get the executable path from a dub package using this command:

dub describe dscanner --data=target-path,target-name --data-list | xargs

But the output always contains a space between target-path and target-name:
/home/user/.dub/packages/dscanner-0.8.0/dscanner/bin/ dscanner

How can I get the full path without a space on a debian system in a 1 liner?

Kind regards
André

Try:
	... | sed -e's@ @@g'


T

Thanks a lot. Works fine:)
dub describe dscanner --data=target-path,target-name --data-list | xargs | sed -e's@ @@g'

Kind regards

It's better to only replace the last occurrence, so it won't break on
paths containing spaces:

    ... | sed 's/\(.*\) /\1/'

There should probably just be a switch to use NUL characters as the
delimiter though.

What about this?
dub describe scanner --data=target-path,target-name --data-list --data-0 | tr -d '\0'

or if you have jq installed:
dub describe dscanner | jq '.targets[0].buildSettings | "\(.targetPath)/\(.targetName)"'

Thanks to all! Yes replacing spaces with NUL really makes sense.

Kind regards
