Set IFS to the pipe character for the read command, then start tailing the file on line two to bypass the text field of A|B|C|D|E, then check variable A to see if it is set to 1 and if it is print all the variables for that line.
Code:
IFS="|"
tail +2 input_file | while read A B C D E; do

echo "
A=$A
B=$B
C=$C
D=$D
E=$E

svn::dump::headers
SVN::Dump::Headers(3) User Contributed Perl Documentation SVN::Dump::Headers(3)NAME
SVN::Dump::Headers - Headers of a SVN dump record
SYNOPSIS DESCRIPTION
An "SVN::Dump::Headers" object represents the headers of a SVN dump record.
METHODS
"SVN::Dump::Headers" provides the following methods:
new( [$hashref] )
Create and return a new empty "SVN::Dump::Headers" object.
If $hashref is given (it can be a blessed hash reference), the keys from the hash are used to initialise the headers.
set($h, $v)
Set the $h header to the value $v.
"_" can be used as a replacement for "-" in the header name.
get($h)
Get the value of header $h.
"_" can be used as a replacement for "-" in the header name.
keys()
Return the list of headers, in canonical order.
as_string()
Return a string that represents the record headers.
type()
It is possible to guess the record type from its headers.
This method returns a string that represents the record type. The string is one of "revision", "node", "uuid" or "format".
The method dies if it can't determine the record type.
ENCAPSULATION
When using "SVN::Dump" to manipulate a SVN dump, one should not directly access the "SVN::Dump::Headers" component of a
"SVN::Dump::Record", but use the "set_header()" and "get_header()" methods of the record object.
SEE ALSO
"SVN::Dump::Record".
