-e option allows you to define Perl code to be executed by the compiler. For example, it’s not necessary to write a “Hello World” program in Perl when you can just type this at the command line.
# perl -e ‘print “Hello World\n”‘
-p option, adds loops around your -e code.It creates code like this:
LINE:
while (<>) {
# your code goes here
} continue {
print or die “-p destination: $!\n”;
}
while (<>) {
# your code goes here
} continue {
print or die “-p destination: $!\n”;
}
-i option. Actually, Perl renames the input file and reads from this renamed version while writing to a new file with the original name. If -i is given a string argument, then that string is appended to the name of the original version of the file. For example, to change all occurrences of “PHP” to “Perl” in a data file you could write something like this:
