bash shell mercurial awk concatenation

You can use a subshell:

( hg status; hg status --ignored ) | awk '( $1 == "?" ) || ( $1 == "I") { print $2 }' | xargs rm -r

You can use the rest of the hg status flags to show what you really want:

hg status -uriamn

That shows unknown files (u), removed files (r), ignored (i), added (a), modified (m) and does so without showing the status prefix.
