in thread Dera Monks, Have create multiple file from one file now I want to match a pattern in each file at the same time do the replacement with adding one to the match pattern.

Done some changes now $lines[0] working fine.. thanks for your help /K creating a problem.. But still issue with $line1

$lines[0] =~ s~/(4947000219)/$1+$n/~e;

Working fine

$lines[1] =~ 's{:20140924105028(\d+)}'{
my $tp = Time::Piece->strptime($1, DATE_FORMAT);
($tp+ONE_MINUTE*2*$n)->strftime(DATE_FORMAT);

 }e;

Error message

    substitution operator is three or four delimiters s/// or s~~~ or s{}{} ... its never s~~ because replacement is missing s~regex~replacement~

    I'll suggest this instead

    my $tp = Time::Piece->strptime($1, DATE_FORMAT);
# out the replacement line
print "tp is: $tp\n"; # we check $tp values here, just for the record

($tp+ONE_MINUTE*2*$n)->strftime(DATE_FORMAT);

    mmmh... this second line needs a var. Try something like this (untested):

    $tp = $tp+ONE_MINUTE*2*$n;
print "tp is now: $tp\n"; # we check $tp again after the changes

$lines[1] =~ 's{:20140924105028(\d+)}'{$tp}e;

    I see also a problem here with 's{}'{}e. Delete the "'" --> s{}{}e
