So, I need to find the instances of a certain font and remove it....so far in my testing I am using the find command with regex to find a font I want to pull out. However, I seem to be slightly stuck, and I am sure the beard stroking Unix geniuses here can help me.

Hi,
I find it really strange while writing a simple regex to match and print the matched string,
dibyajyo@fwtest:~ #perl -e '$x = "root@rashmi>"; print "matched string:$1\n" if ($x =~ /(root@rashmi)/);'
matched string:root

Hi all!
I am trying to register a device in an existing device class, but I am

Hi,
I have following regex condition, however it does not work with different logs having same visible string.I believe it is because of some difference with space character, is it possible to make it work everywhere.
Can someone suggest a better string?

iswalpha
ISWALPHA(3) Linux Programmer's Manual ISWALPHA(3)NAME
iswalpha - test for alphabetic wide character
SYNOPSIS
#include <wctype.h>
int iswalpha(wint_t wc);
DESCRIPTION
The iswalpha() function is the wide-character equivalent of the isalpha(3) function. It tests whether wc is a wide character belonging to
the wide-character class "alpha".
The wide-character class "alpha" is a subclass of the wide-character class "alnum", and therefore also a subclass 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 "alpha" is disjoint from the wide-character class "cntrl".
Being a subclass of the wide-character class "graph", the wide-character class "alpha" 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 "alpha" is disjoint from the wide-character class "punct".
The wide-character class "alpha" is disjoint from the wide-character class "digit".
The wide-character class "alpha" contains the wide-character classes "upper" and "lower".
The wide-character class "alpha" always contains at least the letters 'A' to 'Z' and 'a' to 'z'.
RETURN VALUE
The iswalpha() function returns nonzero if wc is a wide character belonging to the wide-character class "alpha". Otherwise it returns
zero.
CONFORMING TO
C99.
NOTES
The behavior of iswalpha() depends on the LC_CTYPE category of the current locale.
