setting a log_it function

[lawrenzo_1]

Hi all,

I want to use a log_it function as below:

LOGFILE=${DIR}/${HOST}_sapno.log



function log_it {

printf "%s\n" "$*" >> $LOGFILE

}

how can I get the log_it function to record the output of my commands:

eg:

# |log_it

obviously this doesnt work, I have used this function in the past but cant find my notes.

Thanks for any help

Hi Chris:

#!/usr/bin/sh

typeset LOGFILE=/tmp/mylog
function log_it {
printf "%s\n" "$*" >> $LOGFILE
eval "$*" >> $LOGFILE

}

log_it date

Regards!

Hi,

to get your output to a logfile via
# |log_it

you'll have to read stdin in your function:

function log_it {
cat >>$LOGFILE
}

or - to get the output in the logfile and on screen:
function log_it {
tee -a $LOGFILE
}

Hi,

log_it () {
awk '{print}' $@
}

echo "jkjkjkjkjk"|log_it
jkjkjkjkjk

this runs fine on my Hp-UX 11i.
