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_001(3pm) User Contributed Perl Documentation CheckDigits::MBase_001(3pm)NAME
CheckDigits::MBase_001 - compute check digits for UPC (US)
SYNOPSIS
use Algorithm::CheckDigits;
$rv = CheckDigits('upc');
if ($rv->is_valid('012345678905')) {
# do something
}
$cn = $rv->complete('01234567890');
# $cn = '012345678905'
$cd = $rv->checkdigit('012345678905');
# $cd = '5'
$bn = $rv->basenumber('012345678905');
# $bn = '01234567890'
DESCRIPTION
ALGORITHM
1. Add all digits in odd-numbered positions.
2. Multiply the sum from step 1 with 3.
3. Add all digits in even-numbered positions.
4. Add the product from step 2 and the sum from step 3.
5. If the sum from step 4 is 0 modulo 10, the check digit is 0. Else the check digit is 10 minus the sum from step 4 taken modulo 10.
METHODS
is_valid($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.

THANKS
Aaron W. West pointed me to a fault in the computing of the check digit.
