putting commas separated values into a new file line by line

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

from command line, we are passing multiple values separated by commas such as sydney,delhi,NY,Russia. these values are getting stored under $runTest in the script. now i want to create a new file with contents of $runTest but as line by line. example

INPUT (contents of $runTest): sydney,delhi,NY,Russia
OUTPUT (under new file: myfile): sydney
                                 delhi
                                 NY
                                 Russia

To create a new file, use open. `open my $out, '>', 'new_file' or die $!;` [download] If you just need to output the string, you can replace commas by newlines: `my $runTest = 'sydney,delhi,NY,Russia'; print {$out} $runTest =~ tr/,/\n/r;` [download] Use say instead of print if you want a newline after Russia. If you want to store the lines in an array, use split: `my @lines = split /,/, $runTest;` [download] BTW, Sydney, Delhi, and NY are cities, while Russia is a country. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]

i don't understood completely, i just want to have those command line passed values that are further stored under $runTest in a new file as line by line got below error while running the script Bareword found where operator expected at ./fileTest.pl line 10, near "tr/,/\n/r" syntax error at ./fileTest.pl line 10, near "tr/,/\n/r"	[reply]

What Perl version are you using? `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l]
