6.13: How do I process each word on each line?


Use the split function:

while (<>) {
foreach $word ( split ) {
# do something with $word here
}
}

Note that this isn't really a word in the English sense; it's just
chunks of consecutive non-whitespace characters.

To work with only alphanumeric sequences (including underscores), you
might consider

while (<>) {
foreach $word (m/(\w+)/g) {
# do something with $word here
}
}

are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
