I hope this helps . That fails because you're using single quotes. There's no variable substitution inside single quotes. Instead, use double quoted:
code :
COLOR="#$HEX"

To fix this issue I'm trying to escape several special characters in a given string using perl regex. It works fine for all characters except for the dollar sign. I tried the following: , Try this:
code :
my %special_characters;
$special_characters{"_"} = "\\_";
$special_characters{"\\\$"} = "\\\$";
$special_characters{"{"} = "\\{";
$special_characters{"}"} = "\\}";
$special_characters{"#"} = "\\#";
$special_characters{"%"} = "\\%";
$special_characters{"&"} = "\\&";
s/\$/\$/g

I think the issue was by ths following , You should have a look at search and replace using regular expressions.
But to save you time, here is a quick demonstration:
code :
my $str = 'health+development';
$str =~ s/\+/ /; # replace '+' with ' '
print $str;

Hope that helps Use the column function instead of referring to the columns with the shortcut $...:
code :
c(x)= x==1?'using 3:(abs(column(5))):6': x==2?'using 3:(abs(column(7))):8': x==3?'using 3:(abs(column(9))):10':0    
column = c($2)

code :
sh '''
