How to add a new line separating the inputs into a Perl script?
Example:
I'm using the following script:
#!/usr/bin/perl
print 'oi' . '\n' . 'oi,de novo'
And I call by bash as follows:
perl test.pl > a.txt
When opening the file a.txt I get:
oi\noi, de novo
I would expect the file to be:
oi
oi, de novo
Use double quotation marks " instead of single quotation marks ' , so as to allow interpolation of string , \n will be interpreted as line break rather than literally.
#!/usr/bin/perl
print 'oi' . "\n" . 'oi,de novo'
# print "oi\noi,de novo"
