How to add a new line by separating inputs into a Perl script?
Example:
I’m using the following script:
#!/usr/bin/perl
print 'oi' . '\n' . 'oi,de novo'
And I call on the bash as follows:
perl test.pl > a.txt
When opening the file a.txt get:
oi\noi, de novo
I would expect the file to be:
oi
oi, de novo

Use double quotes " instead of single quotes ', in such a way as to enable the interpolation of string, \n will be interpreted as line breaking and not literally.
#!/usr/bin/perl
print 'oi' . "\n" . 'oi,de novo'
# print "oi\noi,de novo"
