apache - Convert bash line to use in perl -

How do I go about changing the following bash line to Pearl? Can I run the system () command, or better way? I'm looking to print out my Appreciate access_log file every day.

In the Bash:

  awk '{print $ 4}' / etc / httpd / log / access_log | Cut-D: -f1 | Uniq -c  

prints the following:

  632 [27 / April / 2014 156 [28 Apr / 2014  

  awk '{print $ 4}' / etc / httpd / logs / access_log | Cut-D: -f1 | UniC-C  

  perl -lane '($ val) = partition /: /, $ F [3]; #The first element of the fourth column # + $ c {$ val} is the element separated by colon; # Increasing the number of frequencies {Print to map {"$ c {$ _} $ _"} keys% c} # 'Do not use print' in any order access.log  

Switch:

• -l automatically adds a new line to the print statement. New lines from
• -l are also deleted; the line read by -n (and -p ).
• -a divides the row into an array on the green space @f .
• -n lines on the lines of the input, but do not print each line.
