Hi,
I wrote a ruby code that writes to a file:
open('file.txt', 'w') {|file| file.write(arr.join("\n")) }
when I try to get the number of line counts
wc -l file.txt
I get the count as 49 instead of 50. How to overcome this? My file might not have a new line at the end. That shouldn't have prevented wc to count the number of actual lines.
Jump to Postwc - word count with the -l option count the number of newlines
This is right from man wc
-l'
`--lines'
Print only the newline counts.
wc - word count with the -l option count the number of newlines

Most utilities work with text files. A text file, by definition, has a newline at the end. If there's no final newline, the last line will not be counted.
