There is nothing wrong with cross-posting questions, but it is considered polite to inform the reader (and provide the link) to prevent duplication of work in various location of the Internet.

For reference, here's the one-liner solution I had posted on that other site before seeing this post here: 

$ echo 'cfg_a 
cfg_b[2:0] 
cfg_c[4:0] 
cfg_d '   |  perl -ne '($cf, $num) = ($1, $2) if /(cfg_\w+)(\[\d:\d\])
+*/; print "logic $num $cf\n"; 
' 
logic  cfg_a 
logic [2:0] cfg_b 
logic [4:0] cfg_c 
logic  cfg_d
