Hi,

I want to run a sequence of commands on UNIX for series of
operations. I would like to have a log of both - the commands as well
as their output.

I can do <command> | tee -a <logfile>. However, it does not
redirect the "command" that I entered into the log file.

How could I get it done?


Thanks in advance,
Shrikrishna

log=/tmp/cmd.log
docmd () {
echo "============" >> $log
date                >> $log
echo "$@"           >> $log
echo "============" >> $log
"$@"           2>&1 >> $log
}

touch $log
tail -f $log & tail_pid=$?

docmd echo 'Howdy?'
docmd ls -l

kill $tail_pid


There's one defect, in that the command line logged lose the words:

docmd echo 'ab cd' ef

would log as:  echo ab cd ef
One Q&D fix would be:

for arg in "$@" ; do
echo -n "$(echo "$arg" | sed -e 's/\(.\)/\\\1/g') "
done    >> $log
echo '' >> $log

instead of:

echo "$@"           >> $log
