Extract a string up to the first occurence of a substring
Hi,
I'm a newbie to shell scripting and have searched the forum but couldn't find what i was looking for.
Basically I have a list of filenames like...
123-fileone.txt
I want to be able to extract the prefix up to the first '-'. So I'd end up with 123. I have attempted it using a pretty basic regex ({F%-*}) but that trips up when there is more than 1 occurrence of '-' in the filename, which there can be.
I'm sure it's a simple thing to do...just not for me
Thanks.
Kirk.

Hi,
I couldn't figure how to extract until last occurence of a character.
I have the string ./dir1/file1/abc.sh
The output should be /dir1/file1
So, the command should display the path until last occurence of "/".
Thanks. (3 Replies)

algorithm::checkdigits::m11_010
CheckDigits::M11_010(3pm) User Contributed Perl Documentation CheckDigits::M11_010(3pm)
NAME
CheckDigits::M11_010 - compute check digits AHV number (CH)
SYNOPSIS
use Algorithm::CheckDigits;
$ahv = CheckDigits('ahv_ch');
if ($ahv->is_valid('123.45.678.113')) {
# do something
}
$cn = $ahv->complete('123.45.678.11');
# $cn = '123.45.678.113'
$cd = $ahv->checkdigit('123.45.678.113');
# $cd = '3'
$bn = $ahv->basenumber('123.45.678.113');
# $bn = '123.45.678.11';
DESCRIPTION
ALGORITHM
1. Beginning left every digit is weighted with 5,4,3,2,7,6,5,4,3,2.
2. The weighted digits are added.
3. The sum from step 2 is taken modulo 11.
4. The checkdigit is 11 minus the sum from step 3. Is the difference 10, the number won't be taken. If the difference is 11, the
checkdigit is 0.
METHODS
is_valid($number)
Returns true only if $number consists solely of numbers and hyphens and the two digits in the middle are valid check digits according
to the algorithm given above.
Returns false otherwise,
complete($number)
The check digit for $number is computed and inserted into the middle of $number.
Returns the complete number with check digit or '' if $number does not consist solely of digits, hyphens and spaces.
basenumber($number)
Returns the basenumber of $number if $number has a valid check digit.
Return '' otherwise.
checkdigit($number)
Returns the check digits of $number if $number has valid check digits.
Return '' otherwise.
EXPORT
None by default.
