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,
I need to find whether the first character in a line is a alphabet or a number. If its a number i should sort it numerically. If its a alphabet i should sort it based on the ASCII value.And if it is something other than alphabet or number then sort it based on ASCII value.
The code i used... (2 Replies)
I have a var storing date
var=`date`
Now the date is returned as

Is there any way to check the date field alone ("2" in above case) and if its a single digit then add a prefix 0 to it and store the result in same variable "var"
My intention in above case is... (3 Replies)

I have a genotype.bim file where it contains information about SNPs and genotype. As a hypothetical example, let's say
genotype.bim

snp2 ... G T
snp3 ... G T

snpN ... C G
where first column identifies each SNP and 5th and 6th column has genotype... (3 Replies)
I wanted to know if there was a more efficient to do this. I was to setup a conditional for every letter of the alphabet, like so (I am parsing an array):
for i in "${arr}"; do
if ]; then
echo "$i starts with A"
else echo "$i does not start with A"
fi
done
I want to do this A-Z, is there... (6 Replies)

iswdigit
ISWDIGIT(3) Linux Programmer's Manual ISWDIGIT(3)NAME
iswdigit - test for decimal digit wide character
SYNOPSIS
#include <wctype.h>
int iswdigit(wint_t wc);
DESCRIPTION
The iswdigit() function is the wide-character equivalent of the isdigit(3) function. It tests whether wc is a wide character belonging to
the wide-character class "digit".
The wide-character class "digit" is a subclass of the wide-character class "xdigit", and therefore also a subclass of the wide-character
class "alnum", of the wide-character class "graph" and of the wide-character class "print".
Being a subclass of the wide character class "print", the wide-character class "digit" is disjoint from the wide-character class "cntrl".
Being a subclass of the wide-character class "graph", the wide-character class "digit" is disjoint from the wide-character class "space"
and its subclass "blank".
Being a subclass of the wide-character class "alnum", the wide-character class "digit" is disjoint from the wide-character class "punct".
The wide-character class "digit" is disjoint from the wide-character class "alpha" and therefore also disjoint from its subclasses "lower",
"upper".
The wide-character class "digit" always contains exactly the digits '0' to '9'.
RETURN VALUE
The iswdigit() function returns nonzero if wc is a wide character belonging to the wide-character class "digit". Otherwise it returns
zero.
CONFORMING TO
C99.
NOTES
The behavior of iswdigit() depends on the LC_CTYPE category of the current locale.
