If your sed supports the -i option, it can do the replacement in-place. Otherwise you will need a small script which writes to a temporary file and then replaces the original file with that.

Code:
find / -type f | xargs sed -i 's/calcuta/kolkata/g'

The sed manual page is probably not a good place to start learning, but any decent Unix tutorial or book will have a section about sed.

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(string, pattern) int Tcl_StringCaseMatch(string, pattern, nocase) ARGUMENTS
char *string (in) String to test. char *pattern (in) Pattern to match against string. May contain special characters from the set *?[]. int nocase (in) Specifies whether the match should be done case-sensitive (0) or case-insensitive (1). _________________________________________________________________ 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 nocase as 1), then the string and pattern are essentially matched in the lower case. KEYWORDS
match, pattern, string Tcl 8.1 Tcl_StringMatch(3)
