sed or awk help or smth...

Hi all,

I will be glad if you can help me.

I have this kind of document:

$cat mistake_file
546488
123456
546887
132548
123456
546887
324645
123456
123456

and I want to replace just first occurence of word or number 123456 in this file with XXXXXX and also to save changes into this file.

it will be not always "123456" and the file is much more longer and this numbers are sometimes in the middle of line... so I want the script in generally not just for this example Smilie

I was trying it with sed but that command replace one occurence in line but on all lines in document or all occurences in documents...

$sed s/123456/XXXXXX/
or
$sed s/123456/XXXXXX/g
or
$sed s/123456/XXXXXX/1

doesn`t worked for me...

I`m not good in awk or nawk but I read somewhere that it should solve my problem... is here anybody who wants and can help? Smilie

Best regards,
oddo Smilie

EDIT: under Solaris (SunOS 5.9)

NAME
patchmedia - modify Solaris media with patches and packages SYNOPSIS
/usr/bin/patchmedia -d media-root [-v] [-o iso] [-l label] pkg_or_patch [pkg_or_patch ...] DESCRIPTION
The patchmedia utility takes a list of patches and packages as input and updates the install miniroot in media-root (the root directory of an on-disk image of a Solaris installation media) to include the specified patches and packages. These patches and packages are also placed in a subdirectory called DU under the Solaris install image. For example: media-root/Solaris_10/DU When booting a system from the updated media, the patches and packages will be part of the booted Solaris image. They will also be applied to the target system being installed at the end of the installation process. If -o is specified, a bootable ISO image is created in the file media.iso that contains the Solaris install media. The ISO image can then be burned onto a CD/DVD with utilities such as cdrw(1) or cdrecord(1). (The latter is not a SunOS man page.) OPTIONS
The following options are supported: -d media-root Top-level directory of on-disk image of Solaris installation media. This is option must be specified. -o iso Create a Solaris ISO image of media-root. -l label Label/volume name of the ISO image (if -o option is specified). If -o is not specified, the name of Solaris directory under media-root, for example, Solaris_10, will be used. -v Verbose. Multiple -v options increase verbosity. OPERANDS
The following operands are supported: pkg_or_patch [pkg_or_patch ...] One or more patches or packages (you can have both patches and packages in a single command) with which the Solaris installation media media-root will be updated. EXAMPLES
Example 1 Updating a Solaris Install Image with Patch and Package The following command updates the Solaris install image in s10u1 by adding patch 123456-07 and package SUNWfoo. # /usr/bin/patchmedia -d s10u1 SUNWfoo 123456-07 ATTRIBUTES
