I usually use this paradigm at the top of a script:

Code:

# Redirect the stdout/stderr to screen AND log file

mkfifo /tmp/$$-err /tmp/$$-out
# to merge stdout/stderr to log file AND screen
( exec tee -a ${FILE_LOG} </tmp/$$-out ) &
( exec tee -a ${FILE_LOG} </tmp/$$-err >&2 ) &

exec 1>/tmp/$$-out
exec 2>/tmp/$$-err
rm -f /tmp/$$-out /tmp/$$-err

zipnote

zipnote(1)						      General Commands Manual							zipnote(1)

NAME

       zipnote - write the comments in zipfile to stdout, edit comments and rename files in zipfile

SYNOPSIS

       zipnote [-w] [-b path] [-h] [-v] [-L] zipfile

ARGUMENTS

       zipfile	Zipfile to read comments from or edit.

OPTIONS

       -w     Write comments to a zipfile from stdin (see below).

       -b path
	      Use path for the temporary zip file.

       -h     Show a short help.

       -v     Show version information.

       -L     Show software license.

DESCRIPTION

       zipnote	writes the comments in a zipfile to stdout.  This is the default mode.	A second mode allows updating the comments in a zipfile as
       well as allows changing the names of the files in the zipfile.  These modes are described below.

EXAMPLES

       To write all comments in a zipfile to stdout use for example

	    zipnote foo.zip > foo.tmp

       This writes all comments in the zipfile foo.zip to the file foo.tmp in a specific format.

       If desired, this file can then be edited to change the comments and then used to update the zipfile.

	    zipnote -w foo.zip < foo.tmp

       The names of the files in the zipfile can also be changed in this way.  This is done by following lines like
	    "@ name"
       in the created temporary file (called foo.tmp here) with lines like
	    "@=newname"
       and then using the -w option as above.

BUGS

       The temporary file format is rather specific and zipnote is rather picky about it.  It should be easier to change file names in a script.

       Does not yet support large (> 2 GB) or split archives.
