NAME

pdfinfo - Portable Document Format (PDF) document information extractor (version 2.01)  

SYNOPSIS

pdfinfo [options] [PDF-file]  

DESCRIPTION

Pdfinfo prints the contents of the 'Info' dictionary (plus some other useful information) from a Portable Document Format (PDF) file.

The 'Info' dictionary contains the following values:

title
subject
keywords
author
creator
producer
creation date
modification date

In addition, the following information is printed:

page count
encrypted flag (yes/no)
print and copy permissions (if encrypted)
linearized (yes/no)
 

CONFIGURATION FILE

Pdfinfo reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /etc/xpdfrc (but this location can be changed when pdfinfo is built). See the xpdfrc(5) man page for details.  

OPTIONS

Many of the following options can be set with configuration file commands. These are listed in square brackets with the description of the corresponding command line option.
-meta
Prints document-level metadata. (This is the "Metadata" stream from the PDF file's Catalog object.)
-enc encoding-name
Sets the encoding to use for text output. The encoding-name must be defined with the unicodeMap command (see xpdfrc(5)). This defaults to "Latin1" (which is a built-in encoding). [config file: textEncoding]
-opw password
Specify the owner password for the PDF file. Providing this will bypass all security restrictions.
-upw password
Specify the user password for the PDF file.
-cfg config-file
Read config-file in place of ~/.xpdfrc or the system-wide config file.
-v
Print copyright and version information.
-h
Print usage information. (-help and --help are equivalent.)
 

EXIT CODES

The Xpdf tools use the following exit codes:
0
No error.
1
Error opening a PDF file.
2
Error opening an output file.
3
Error related to PDF permissions.
99
Other error.
