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)

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 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 non-zero if wc is a wide character belonging to the wide character class "digit". Otherwise it returns zero.

The behaviour of iswdigit depends on the LC_CTYPE category of the current locale.
