[PATCH 00/10] use the $( ... ) construct for command substitution

This patch series continues the changes introduced with the merge 6753d8a85d543253d95184ec2faad6dc197f248:

    Merge branch 'ep/shell-command-substitution'

    Adjust shell scripts to use $(cmd) instead of `cmd`.

The last patch eliminates entirely the backquotes without replacing them for optimization.

This is the  seventh series, the other will be sent separately.
