Replace variable string with text
Hi All, Hoping someone can help....

I am trying to work out how I can ammend a log file to remove variable strings in order to remove confidential information which I cant pass on.

As an example I have used phone numbers. A large log file contains multiple lines containing something like the below

Code:
ses:3317] start call ms <xxxxxxxxxxxx> id < 13102 > id2 <0a23> index 858

In the code above i have placed x's where the variable numbers will be that i need to change, these varible numbers i need to be able to anonymize/replace. Is there a way of doing this ? Note that the numbers will always start with a set prefix as the first 2/3 digits also.

Any help would be much appreciated.

Thanks

xfs_ncheck

xfs_ncheck(8)						      System Manager's Manual						     xfs_ncheck(8)

NAME

       xfs_ncheck - generate pathnames from i-numbers for XFS

SYNOPSIS

       xfs_ncheck [ -i ino ] ... [ -f ] [ -s ] [ -l logdev ] device

DESCRIPTION

       xfs_ncheck  with no -i arguments generates an inode number and pathname list of all files on the given filesystem. Names of directory files
       are followed by /..  The output is not sorted in any particular order.  The filesystem to be examined is specified by the device  argument,
       which should be the disk or volume device for the filesystem.  Filesystems stored in files can also be checked, using the -f flag.

OPTIONS

       -f	Specifies  that the filesystem image to be processed is stored in a regular file at device (see the mkfs.xfs -d file option). This
		might happen if an image copy of a filesystem has been made into an ordinary file.

       -l logdev
		Specifies the device where the filesystem's external log resides.  Only for those filesystems which use an external log.  See  the
		mkfs.xfs -l option, and refer to xfs(5) for a detailed description of the XFS log.

       -s	Limits	the  report to special files and files with setuserid mode.  This option may be used to detect violations of security pol-
		icy.

       -i ino	Limits the report to only those files whose inode numbers follow.  May be given multiple times to select multiple inode numbers.

       If the filesystem is seriously corrupted, or very busy and looks like it is corrupt, a message of the  form  that  would  be  generated	by
       xfs_check(8) may appear.

       xfs_ncheck is only useful with XFS filesystems.
