implicitly redirecting stdout to a file
Is there a way to redirect all stdout to a file implicitly - like defining stdout=/home/me/process.log - so that all "echo" commands in several scripts/subscripts are written to that file; instead of having to edit all scripts to redirect the "echo" (e.g. echo 'This is a test ' >> =/home/me/process.log)?

Hi everybody,
I am trying to do the thing you see in the title, and I can't simply do
a=$(svn up)
echo $a
because the program (svn) gives output on lots of lines and in the variable the output is stored on only one line (resulting in a horribly formatted text). Any tips?
Thanks,... (2 Replies)

NAME
flvtool2 - a manipulation tool for flash video files
SYNOPSIS
flvtool2 [-ACDPUVaciklnoprstvx]...[-key:value]...in-path|stdin[out-path|stdout]
DESCRIPTION
If out-path is omitted, in-path will be overwritten. In-path can be a single file, or a directory. If in-path is a directory, out-path has
to be likewise, or can be omitted. Directory recursion is controlled by the -r switch. You can use stdin and stdout keywords as in- and
out-path for piping or redirecting.
Chain commands like that: -UP (updates FLV file than prints out meta data)
COMMANDS
-A Adds tags from -t tags-file
-C Cuts file using -i inpoint and -o outpoint
-D Debugs file (writes a lot to stdout)
-H Helpscreen will be shown
-P Prints out meta data to stdout
-U Updates FLV with an onMetaTag event
SWITCHES
-a Collapse space between cut regions
-c Compatibility mode calculates some onMetaTag values differently
-key:value
Key-value-pair for onMetaData tag (overwrites generated values)
-i timestamp
Inpoint for cut command in miliseconds
-k Keyframe mode slides onCuePoint(navigation) tags added by the add command to nearest keyframe position
-l Logs FLV stream reading to stream.log in current directory
-n Number of tag to debug
-o timestamp
Outpoint for cut command in miliseconds
-p Preserve mode only updates FLVs that have not been processed before
-r Recursion for directory processing
-s Simulation mode never writes FLV data to out-path
-t path
Tagfile (MetaTags written in XML)
-v Verbose mode
-x XML mode instead of YAML mode
