Code:
 wc -l < filename

gives the result without the filename, because wc is reading from stdin.

{n++} - for every line read from input, add one to n. The first time n is encountered it is assumed to be zero.
END{} runs after all of the lines in the file have been read.

PX_GET_INFO(3)															    PX_GET_INFO(3)

px_get_info - Return lots of information about a paradox file

SYNOPSIS
array px_get_info (resource $pxdoc) DESCRIPTION
PARAMETERS
o $pxdoc - Resource identifier of the paradox database as returned by px_new(3). RETURN VALUES
Returns an associated array with lots of information about a paradox file. This array is likely to be extended in the future. o fileversion -Version of file multiplied by 10, e.g. 70. o tablename -Name of table as stored in the file. If the database was created by pxlib, then this will be the name of the file without the extension. o numrecords -Number of records in this table. o numfields -Number of fields in this table. o headersize -Number of bytes used for the header. This is usually 0x800. o recordsize -Number of bytes used for each record. This is the sum of all field sizes (available since version 1.4.2). o maxtablesize - This value multiplied by 0x400 is the size of a data block in bytes. The maximum number of records in a datablock is the integer part of (maxtablesize * 0x400 - 8) / recordsize. o numdatablocks - The number of data blocks in the file. Each data block contains a certain number of records which depends on the record size and the data block size (maxtablesize). Data blocks may not necessarily be completely filled. o numindexfields - Number of fields used for the primary index. The fields do always start with field number 1. o codepage - The DOS codepage which was used for encoding fields with character data. If the target encoding is not set with px_set_targeten- coding(3) this will be the encoding for character fields when records are being accessed with px_get_record(3) or px_retrieve_record(3).
