Its typical use is extracting information from a text file and printing out report for converting a text file into another form. This is because it got its name after the expression, "Practical Extraction and Report Language". Programs written in Perl are called Perl scripts, whereas system programs to execute Perl scripts are called Perl program. Perl is an interpreted language. When a Perl program run, it is first compiled into a byte code, then it is converted into machine instructions. So writing something in Perl instead of C saves your time. It supports most of the operating systems and is listed in Oxford English dictionary. Its concepts and syntax is taken from many languages like awk, bourne shell, C, sed and even English.
