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)
Hi all-
I've got a file that will have multiple columns. In one column there will be a string that is 10 digits in length, but I need to trim the first four zeros to make it 6 characters?
example:
0000001234
0000123456
0000234566
0000000321
output:
001234
123456
234566
000321 (5 Replies)

CheckDigits::M16_001(3pm) User Contributed Perl Documentation CheckDigits::M16_001(3pm)NAME
CheckDigits::M16_001 - compute check digits for ISAN
SYNOPSIS
use Algorithm::CheckDigits;
$isan = CheckDigits('isan');
if ($isan->is_valid('123A567B8912E01A')) {
# do something
}
$cn = $isan->complete('123A567B8912E01');
# $cn = '123A567B8912E01A'
$cd = $isan->checkdigit('123A567B8912E01A');
# $cd = '4'
$bn = $isan->basenumber('123A567B8912E01A');
# $bn = '123A567B8912E01'
DESCRIPTION
ALGORITHM
1. "a(1) = 16"
"b(i) = a(i) % 17 +d(i)", where d(i) is the decimal value of the hexdigit at position i.
"c(i) = b(i) % 16"
"a(i) = c(i-1) * 2", for i greater than 1
2. Beginning left for each i = 1..16, "a", "b", "c" are computed.
3. The check digit is the value for "d(16)" where "c(16)" equals 1.
4. The check digit is appended as hexadecimal value to the number.
METHODS
is_valid($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.
