What function do you mean? Any function defined in a source file? Or any function used in a source file? Be more specific.
Yes, by using the preg_match() function
The Perl Chomp function is a programming function that remove the "newline" character at the end of the string. One can use the Perl Chomp function to remove any character that has the same value as the current one.
The Perl split function is used to split a string into smaller section. One can find a guide on how to use a Perl split function on various websites including Perlmeme.

#!/usr/bin/perl print 'java program';
This question is very nearly meaningless. Perl is a programming language; the reliability of any given Perl program depends on the talent and insight of the programmer.
Perl is a programming language, and to use it requires many hours of reading about it and of practice writing programs in it.

Perl is both compiled and interpreted language. In the traditional sense, Perl is a pure interpreted language. The reference Perl program is a prototypical two-stage interpreter: when a Perl script is invoked via #!/bin/perl (or similar), the perl interpreter performs a language parsing on the source code, creating an internal (to the perl interpreter) representation of program, which is then translated into binary code for execution. Every invocation of a perl program requires this translation/interpretation to be completed. There are several projects which can take perl source code and compile it down to a binary executable (that is, bypass the whole repeated translate/interpret phase each time). However, these are NOT complete - even the best can only manage about 95% of the perl code available. That is, these perl compiler are incomplete implementations of the Perl language. They can be very useful, but are not complete substitutes for the Perl interpreter. The real answer is that Perl was designed to be an interpreted language from the start; attempts to turn Perl into a compiled language are faced with the difficulty of Perl's sprawling syntax and complete lack of design for compilation, and thus, struggle to implement all the languages features in a compiler.
The grep function in Perl is the command-line function which can be used to search in a data set for lines which match a regular expression. The grep function is essentially a tool that can be used to search for particular information within the data.
