Error while trying to print message
Hi all

Geting this error while trying to print message as :
./logfunc[4]: print: bad file unit number
heres what i m trying to do :

log_date="$(date '+%d/%m/%Y %H:%M:%S')"
log_type="Message"
print "${log_date}: ${log_type}"
print -u3 "${log_date}: ${log_type}"

this error is due to print -u3 option...
Can anyone explain the reason and wht does this option u3 does ?

Thanks in anticipation ,

Warm Regards,
Navatha

With the -u3 option print sends its output to file descriptor 3.
To redirect the output to a file you can do something like:

Code:
3 > file
print -u3 "${log_date}: ${log_type}"

To print the output to the screen just remove the option.
