You can't put a regular expression into a string comparison like that, you have to use a regular expression operator:
Note that this will ONLY work in bash, not ksh or anything, since only bash has regex support like this. You could also do it with case, which should work in more shells:

Hi Folks
Probably an easy one here but how do I get a sequence to get used as mentioned. For example in the following I want to automatically create files that have a 2 digit number at the end of their names:

Hello all! I've looked all over the internet and this site and have come up a loss with an easy way to make a bash script to do what I want to do. I have a file with a naming convention as follows:

Hi,
I have a requirement where I have to remove duplicates from a file based on the first 8 chars (It is fixed width file of 10 chars length) and whenever a duplicate row is found, its original row's last 2 chars should be updated to all 0's.
I thought of using

re_comp
RE_COMP(3) BSD Library Functions Manual RE_COMP(3)NAME
re_comp, re_exec -- regular expression handler
LIBRARY
Compatibility Library (libcompat, -lcompat)
SYNOPSIS
#include <unistd.h>
char *
re_comp(const char *s);
int
re_exec(const char *s);
DESCRIPTION
This interface is made obsolete by regex(3).
The re_comp() function compiles a string into an internal form suitable for pattern matching. The re_exec() function checks the argument
string against the last string passed to re_comp().
The re_comp() function returns 0 if the string s was compiled successfully; otherwise a string containing an error message is returned. If
re_comp() is passed 0 or a null string, it returns without changing the currently compiled regular expression.
The re_exec() function returns 1 if the string s matches the last compiled regular expression, 0 if the string s failed to match the last
compiled regular expression, and -1 if the compiled regular expression was invalid (indicating an internal error).
The strings passed to both re_comp() and re_exec() may have trailing or embedded newline characters; they are terminated by NULs. The regu-
lar expressions recognized are described in the manual entry for ed(1), given the above difference.
DIAGNOSTICS
The re_exec() function returns -1 for an internal error.
The re_comp() function returns ``no previous regular expression'' or one of the strings generated by regerror(3).
SEE ALSO ed(1), egrep(1), ex(1), fgrep(1), grep(1), regex(3)HISTORY
The re_comp() and re_exec() functions appeared in 4.0BSD.
