What Others Think

Unquoted PE, especially when using rm is a very bad practice. i.e. rm "$arq" Generally, using ''cut'' is useless here, since identify support -format rm_by_size () { for p in *.png; do s=$(identify -format '%wx%h' "$i"); [[ $s = "$1" ]] || rm "$i"; done }

in this case maybe awk can be better than cut awk {'print $3'}

rkirmizi, Read my comment - identify has a -format option, therefore the is not need to use another program to take the relevant fields.
