This is a similar question but counts the matches in the entire file:
Is there a Perl shortcut to count the number of matches in a string?
Instead I want the number of matches to count line by line, using perl on bash.
Example: ~/test.txt
one.two.three.four
one.two.three.four
one.two.three.four
one.two.three.four
This is the bash command line I use:
perl -0777snE 'my @count = /\./gm; say scalar @count' -- ~/test.txt
Which returns:
12
Instead I want it to count line by line and return to me:
3
3
3
3
How can I get this?
Simple:
$ perl -nE 'my @count = /\./g; say scalar @count' file
3
3
3
3
Don't use -0777 if you don't need it.
If you need it:
perl -0777 -nE 'do{ my @count = /\./g; say scalar @count } for split /\n/' file
