taxa names in phylogenetic tree

Question

[erick_rc93]

I have a phylogenetic tree in newick format, and I would like to remove some fragments of the name of the taxa,

1_[genus_specie_1]_characters:0.2654682758,(((((((((((((((2_[genus_specie_2]_characters:0.0379334280,54_[genus_specie_2]_characters:0.0605802067)/1/100:0.0121248674,(3_[genus_specie_3]_characters:0.0206432295,4_[genus_specie_4]_characters:0.0141250479)/1/100:0.0647820408)/1/100:0.0235327264,30_[genus_specie_5]_characters

I would like to remove the fragments out of the square brackets, for example

genus_specie_1:0.2654682758,(((((((((((((((genus_specie_2:0.0379334280,genus_specie_2:0.0605802067)/1/100:0.0121248674,(genus_specie_3:0.0206432295,genus_specie_4:0.0141250479)/1/100:0.0647820408)/1/100:0.0235327264,genus_specie_5

I have tried with one liner perl to remove all square brackets

perl -i -pe 'y/[]//d' file.nwk

but it only remove square brackets.

can anyone help me with this ?
