Removing repeated characters, including spaces, in one line
- by Thumper
I currently have a string, say $line='55.25040882, 3,,,,,,', that I want to remove all whitespace and repeated commas and periods from. Currently, I have:
$line =~ s/[.,]{2,}//;
$line =~ s/\s{1,}//;
Which works, as I get '55.25040882,3', but when I try
$line =~ s/[.,\s]{2,}//;
It pulls out the ", " and leaves the ",,,,,,". I want to retain the first comma and just get rid of the whitespace.
Is there a way to elegantly do this with one line of regex? Please let me know if I need to provide additional information.
