Notable thing about above line is "|" appears at 62nd position. When the same line is assigned in a variable in a ksh script, using

it appears as ... (4 Replies)

Hi ALL
I have a shell script named setUP in which i am sourcing one variable like
source var_name="CLASSPATH".
When i call it as ./setUP, it does not set the var_name variable. But when i call it like . ./setUP then var_name is set up. What is the difference between this two calls?

Algorithm::DiffOld(3) User Contributed Perl Documentation Algorithm::DiffOld(3)NAME
Algorithm::DiffOld - Compute `intelligent' differences between two files / lists but use the old (<=0.59) interface.
NOTE
This has been provided as part of the Algorithm::Diff package by Ned Konz. This particular module is ONLY for people who HAVE to have the
old interface, which uses a comparison function rather than a key generating function.
Because each of the lines in one array have to be compared with each of the lines in the other array, this does M*N comparisions. This can
be very slow. I clocked it at taking 18 times as long as the stock version of Algorithm::Diff for a 4000-line file. It will get worse
quadratically as array sizes increase.
SYNOPSIS
use Algorithm::DiffOld qw(diff LCS traverse_sequences);
@lcs = LCS( @seq1, @seq2, $comparison_function );
$lcsref = LCS( @seq1, @seq2, $comparison_function );
@diffs = diff( @seq1, @seq2, $comparison_function );
traverse_sequences( @seq1, @seq2,
{ MATCH => $callback,
DISCARD_A => $callback,
DISCARD_B => $callback,
},
$comparison_function );
COMPARISON FUNCTIONS
Each of the main routines should be passed a comparison function. If you aren't passing one in, use Algorithm::Diff instead.
These functions should return a true value when two items should compare as equal.
For instance,
@lcs = LCS( @seq1, @seq2, sub { my ($a, $b) = @_; $a eq $b } );
but if that is all you're doing with your comparison function, just use Algorithm::Diff and let it do this (this is its default).
Or:
sub someFunkyComparisonFunction
{
my ($a, $b) = @_;
$a =~ m{$b};
}
@diffs = diff( @lines, @patterns, &someFunkyComparisonFunction );
which would allow you to diff an array @lines which consists of text lines with an array @patterns which consists of regular expressions.
This is actually the reason I wrote this version -- there is no way to do this with a key generation function as in the stock
Algorithm::Diff.
