File Update
Hi
I have a running program with different output files updating for given loops but for one of the files I want to keep all data (ie not override it) but always concatenate the last data to the previous ones. This needs to be done for given time intervals (lets say every 45 mins)
Is there anyway to do that with sed?

macstream
MACSTREAM(1) General Commands Manual MACSTREAM(1)
NAME
macstream - Convert a series of files to a MacBinary stream
SYNOPSIS
macstream [ - options ] files
DESCRIPTION
macstream takes the files specified in files and combines them to a MacBinary stream on standard output subject to the options specified.
If files also specifies directories they are followed recursively, and all files found will be put in the MacBinary stream, together with
directory information.
OPTIONS
In the absence of any options, macstream takes the specified files and silently combines them to a MacBinary stream, writing the result to
standard output. Directories named in files are followed recursively, all files found will be put in the MacBinary stream, together with
directory information. Files are assumed to be in MacBinary format. However, if the filename ends with .info the file is assumed to be
the info fork of a MacIntosh file split amongst more than one file. In that case the files with .data and .rsrc extension are also read
(if present). Also, if the info fork is mentioned in the parameter list, the names of data and resource forks can also be mentioned, but
those will be ignored (this is to allow wild-card expansion by the shell.) Further, if some form of AppleShare is supported by the
installed program, and if the current directory, or one of the directories found during recursive processing, is a directory in the format
of the supported version of AppleShare, those files will be handled according to the properties of AppleShare.
-r No intelligent file-processing is performed; all files named are assumed to be plain resource files, and are written as MacIntosh
resource files with creator "RSED" and type "RSRC", unless another creator and/or type are specified.
-d No intelligent file-processing is performed; all files named are assumed to be plain data files, and are written as MacIntosh data
files with creator "MACA" and type "TEXT", unless another creator and/or type are specified.
-u As -d, but the codes for CR and LF are interchanged.
-U Is a synonym for -u.
-c creator
Defines the creator name to be used if one of the previous options is specified.
-t type
Defines the type name to be used if one of the previous options is specified.
-l List every file and directory processed.
-i Do not output files, give information only (implies -l.)
-q Ask the user for every file/directory whether it should be visited (implies -l.)
-V Gives the patchlevel of the program, and other information. Other options are ignored and the program quits immediately.
-H Give short information about the options. Other options are ignored and the program quits immediately.
BUGS
As this is a beta release, there may still be some problems.
