Top Forums UNIX for Dummies Questions & Answers Redirect output of echo to a file Post 302842547 by ASC on Friday 9th of August 2013 12:23:35 PM

That is what i exactly want .When i execute the script i don't want to clutter the console with lots of echo statements. Script will just say
Code:
 echo "installation started "
printline "all intermediate debugging statements  are redirected to text file"
echo " installation complete or refer to above log file for error details."

Idea is console will show minimum statements and redirect to log files whenever required.
Can anyone tell me why the printline function i wrote is logging everything correctly except the last echo statement in the script ?
