logging to file
I am trying to figure a way to have a log file and still keep the output in the terminal in a script.
The example below logs to a file nicely but i still want the output in the terminal as well

Code:
#!/bin/bash
#Create a log

exec >> /path/to/my/logfile

echo "hello world"

Any help would be much appreciated, ive played with tee am im sure thats the way, but just cant figure it out.

Code:
echo "This go to log (create it) and screen" | tee logfile.log

echo "This go to log (update it) and screen" | tee -a logfile.log

Hi,
I think tee is the way to go. The "-a" option is the key. Here's an example,

tail /var/log/messages | tee -a messy.log

this will give You stdout to console as well as written to a file.

Perhaps try the script utility program?
