how to find and replace strings in multiple files

Hi All,
Iam new to unix, I need to find string and replace it in the file name. Like
text_123_0.txt,text_123_1.txt,text_123_2.txt. I need to search 123 and replace it with 234 . Is there any unix command to replace them in single command since i have 5 directories. So i need to go each and every directory.
I need to replace 123 with 234 in each directory. Please give any suggestions

NAME
wrjpgcom - insert text comments into a JPEG file SYNOPSIS
wrjpgcom [ -replace ] [ -comment text ] [ -cfile name ] [ filename ] DESCRIPTION
wrjpgcom reads the named JPEG/JFIF file, or the standard input if no file is named, and generates a new JPEG/JFIF file on standard output. A comment block is added to the file. The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file. Although the standard doesn't actually define what COM blocks are for, they are widely used to hold user-supplied text strings. This lets you add annotations, titles, index terms, etc to your JPEG files, and later retrieve them as text. COM blocks do not interfere with the image stored in the JPEG file. The maximum size of a COM block is 64K, but you can have as many of them as you like in one JPEG file. wrjpgcom adds a COM block, containing text you provide, to a JPEG file. Ordinarily, the COM block is added after any existing COM blocks; but you can delete the old COM blocks if you wish. OPTIONS
Switch names may be abbreviated, and are not case sensitive. -replace Delete any existing COM blocks from the file. -comment text Supply text for new COM block on command line. -cfile name Read text for new COM block from named file. If you have only one line of comment text to add, you can provide it on the command line with -comment. The comment text must be sur- rounded with quotes so that it is treated as a single argument. Longer comments can be read from a text file. If you give neither -comment nor -cfile, then wrjpgcom will read the comment text from standard input. (In this case an input image file name MUST be supplied, so that the source JPEG file comes from somewhere else.) You can enter multiple lines, up to 64KB worth. Type an end-of-file indicator (usually control-D) to terminate the comment text entry. wrjpgcom will not add a COM block if the provided comment string is empty. Therefore -replace -comment "" can be used to delete all COM blocks from a file. EXAMPLES
Add a short comment to in.jpg, producing out.jpg: wrjpgcom -c "View of my back yard" in.jpg > out.jpg Attach a long comment previously stored in comment.txt: wrjpgcom in.jpg < comment.txt > out.jpg or equivalently wrjpgcom -cfile comment.txt < in.jpg > out.jpg SEE ALSO
