I have a file with fixed number of columns (total 58 columns) delimeted by pipe (|). Due to a bug in the application the export file does not come with fixed number of columns. The missing data columns are being replaced by blank in the output file. In one line I can have 25 columns (33 columns blank) populated and in next one I can have 57 columns (1 column blank) populated. I need to fill blanks with '|0' (pipe zero) in each line to make 58 columns.
Example (with 10 columns):
Input file:
File is very big (1 GB) so we have to take care of performace also. It is better if this does not run for hours and hours. Thanks for your help.

column
COLUMN(1) BSD General Commands Manual COLUMN(1)NAME
column -- columnate lists
SYNOPSIS
column [-tx] [-c columns] [-s sep] [file ...]
DESCRIPTION
The column utility formats its input into multiple columns. Rows are filled before columns. Input is taken from file operands, or, by
default, from the standard input. Empty lines are ignored.
The options are as follows:
-c Output is formatted for a display columns wide.
-s Specify a set of characters to be used to delimit columns for the -t option.
-t Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with
the characters supplied using the -s option. Useful for pretty-printing displays.
-x Fill columns before filling rows.
column exits 0 on success, >0 if an error occurred.
ENVIRONMENT
COLUMNS The environment variable COLUMNS is used to determine the size of the screen if no other information is available.
EXAMPLES
(echo "PERM LINKS OWNER GROUP SIZE MONTH DAY HH:MM/YEAR NAME";
ls -l | sed 1d) | column -t
