Shell Programming and Scripting

$ cat -vet file1
^[[36m20014:35:14.20232 90], [ 80|42^[[0m$
^[[34m200:35:14. 87], [ 80| ^[[0m$

$ cat -vet file1 | sed s/^\\^\\[\\[..m//g | sed s/\\^\\[\\[0m\\$//g
20014:35:14.20232 90], [ 80|42
200:35:14. 87], [ 80| 

The idea is to remove the begin-end pattern: "^[[<NR>m ..... ^[[<NR>m$"
This characters only show when using the option with cat, otherwise the text appears in color.

sed -i 's/[^[:print:]]/g'

open HNDL, "<$ARGV[0]" or die "Cannot open the file";
while(read HNDL, $ch,1)
        {
        if((ord($ch) >=32) && (ord($ch) <=127)) { print $ch; }
        }
close HNDL;

I need to remove the begin-end pattern: "^[[<NR>m ..... ^[[<NR>m$" for each line in the file not the ESCape char.
