Turn POD into Readable Terminal Text with pod2text

You will convert a Perl POD file, or documentation embedded in a Perl source file, into plain text that is suitable for a terminal, a redirect, or a checked-in documentation file. This guide uses the pod2text installed with Perl 5.38.2 on this machine. Allow about 10 minutes for a first conversion.

Before you start

You need a shell, Perl's pod2text command, and a readable input file containing POD. Check the command before working on a real document:

command -v pod2text
pod2text -h | sed -n '1,12p'
perl -v | sed -n '1,3p'

Expected output includes a path such as /usr/bin/pod2text, a usage synopsis, and Perl version 5.38.2 or another installed version. This is a read-only check. No elevated privileges are needed.

1. Convert a POD file to standard output

Give the input path as the first argument. With no output path, formatted text is written to standard output:

pod2text path/to/README.pod

A POD heading becomes a text heading and ordinary paragraphs are wrapped for the terminal. Markup such as C<code> is rendered for reading rather than printed as POD syntax. The normal right margin is column 76, and regular text is indented by four spaces.

pod2text --width=72 path/to/README.pod

The short form is -w 72. Do not confuse this with the left margin: --margin moves all output, while --indent changes the indentation of regular text and =over blocks.

2. Save the result without changing the source

Supply an output path after the input path when you want a file:

pod2text path/to/README.pod /tmp/README.txt
sed -n '1,80p' /tmp/README.txt

Use a destination you control. The command writes the formatted result there; it does not edit the POD input. If the destination is an existing important file, stop and inspect the path first. A mistaken output path can replace that file, and the manpage does not promise a backup.

To keep the generated text in a project, write to a temporary name, inspect it, then replace the intended file only after the comparison is correct:

pod2text docs/guide.pod /tmp/guide.txt
diff -u docs/guide.txt /tmp/guide.txt

If the comparison is wrong, delete or ignore the temporary file and fix the POD. Your source remains the recovery copy.

3. Process a stream or several files

When the input argument is omitted, pod2text reads standard input. Use - explicitly when a script or pipeline makes the input source less obvious:

printf '%s\n' '=head1 Status' '' 'Generated from a stream.' | pod2text --width=60 -

The trailing - is the input name here, not a request for binary output. The result is text on standard output, so it can be piped into a pager or another read-only command.

Several input and output files can be supplied as pairs. This is useful when one process needs to render a small set of documents:

pod2text one.pod one.txt two.pod two.txt

Keep the pairs together. An extra or missing path can make the command interpret a filename as the wrong kind of argument.

4. Choose encoding deliberately

By default, output uses the input file's declared encoding, or UTF-8 when no encoding is declared on this non-EBCDIC system. For a known output contract, select an encoding explicitly:

pod2text --encoding=UTF-8 path/to/README.pod /tmp/README.txt
file -bi /tmp/README.txt

The --utf8 option is an equivalent compatibility spelling for UTF-8. Output encoding does not tell POD how to decode its input. If the source is not US-ASCII, declare its input encoding near the top of the POD with an =encoding command, normally before the main content. Otherwise Pod::Simple may guess and warn, especially for non-ASCII text.

If a character cannot be represented in the selected output encoding, the default error handling is die. You can choose --errors=stderr, --errors=pod, or --errors=none, but those modes trade a hard failure for a warning, an error section, or ignored errors. Use them only when that trade-off is part of your output policy.

5. Keep automation predictable

For scripts, check the exit status and capture standard error separately:

if pod2text --errors=die input.pod output.txt 2>output.err; then
    test ! -s output.err
    printf '%s\n' 'POD conversion passed'
else
    status=$?
    printf 'POD conversion failed (status %s)\n' "$status" >&2
    sed -n '1,40p' output.err >&2
fi

With default error handling, a POD syntax error aborts with status 255. If a document produces no output, the command exits with status 1. A successful status does not mean every warning has vanished: for example, --errors=pod can include a POD ERRORS section while still returning 0 because output exists.

Leave the ANSI output, --overstrike, and --termcap options out of files intended for plain text. They add terminal presentation or control sequences. --termcap also depends on terminal information such as COLUMNS and TERMCAP, so its result can vary between sessions.

Done means

• pod2text -h runs from the expected Perl installation.
• The input file is unchanged and the output path is the one you inspected.
• Output width and encoding are explicit when another tool depends on them.
• Your script checks the exit status and keeps diagnostics separate from the rendered text.
