Folks,
Is there a simple way to replace one digit by two digit using sed.
Example,
mydigit1918_2006_8_8_lag1.csv should be
mydigit1918_2006_08_08_lag01.csv.
I tried this way, but doesn't work.
echo mydigit1989_2006_8_8_lag1.csv|sed 's/]/0]/'
Thank you, (5 Replies)

I want to write/print a number through a shell script up to its last significant digit (LSD) after the decimal point.
Say,
x=10.00056000000000000
I want to print x as x=10.00056.
Note that x can be any thing so I cannot know the position of the LSD always.
Thanks. (16 Replies)

CheckDigits::MBase_002 - compute check digits for blood bags (DE), BZUe (DE), VAT Registration Number (DE)
SYNOPSIS
use Algorithm::CheckDigits;
$bb = CheckDigits('blutbeutel');
if ($bb->is_valid('2761011234567893')) {
# do something
}
$cn = $bb->complete('276101123456789');
# $cn = '2761011234567893'
$cd = $bb->checkdigit('2761011234567893');
# $cd = '3'
$bn = $bb->basenumber('2761011234567893');
# $bn = '276101123456789';
DESCRIPTION
ALGORITHM
1. Start with values P = 10, S = 0.
2. Beginning left you do the following for all digits
1. S = (P + digit) modulo 10
2. If S is 0 then S = 10.
3. P = (2 * S) modulo 11
3. The check digit is (11 - P) modulo 10.
METHODS
is_valid($number)
Returns true only if $number consists solely of numbers and the last digit is a valid check digit according to the algorithm given
above.
Returns false otherwise,
complete($number)
The check digit for $number is computed and concatenated to the end of $number.
Returns the complete number with check digit or '' if $number does not consist solely of digits and spaces.
basenumber($number)
Returns the basenumber of $number if $number has a valid check digit.
Return '' otherwise.
checkdigit($number)
Returns the checkdigit of $number if $number has a valid check digit.
Return '' otherwise.
EXPORT
None by default.
