Print a Search Pattern after modification

Using either vim or awk or sed

If I wish to to search for an unknown pattern - lets say 1B2495 or 1Q2345

so Search pattern : 1[A-Z][0-9][0-9][0-9][0-9]

and replace the 1 with 2 to print out :

2B2495 or 2Q2345

what are the possible commands.

Struggling here - help would be appreciated.

Tcl_StringMatch(3)					      Tcl Library Procedures						Tcl_StringMatch(3)

__________________________________________________________________________________________________________________________________________________

NAME
Tcl_StringMatch, Tcl_StringCaseMatch - test whether a string matches a pattern SYNOPSIS
#include <tcl.h> int Tcl_StringMatch(str, pattern) int Tcl_StringCaseMatch(str, pattern, flags) ARGUMENTS
const char *str (in) String to test. const char *pattern (in) Pattern to match against string. May contain special characters from the set *?[]. int flags (in) OR-ed combination of match flags, currently only TCL_MATCH_NOCASE. 0 specifies a case-sensitive search. _________________________________________________________________ DESCRIPTION
This utility procedure determines whether a string matches a given pattern. If it does, then Tcl_StringMatch returns 1. Otherwise Tcl_StringMatch returns 0. The algorithm used for matching is the same algorithm used in the string match Tcl command and is similar to the algorithm used by the C-shell for file name matching; see the Tcl manual entry for details. In Tcl_StringCaseMatch, the algorithm is the same, but you have the option to make the matching case-insensitive. If you choose this (by passing TCL_MATCH_NOCASE), then the string and pattern are essentially matched in the lower case. KEYWORDS
match, pattern, string Tcl 8.5 Tcl_StringMatch(3)
