I'm not sure ... whether i have understood you correctly.

But here is advantage and using of logfiles.

Logfiles fecilitates you to see what happened to yr out put statements such as "echo " .... etc.

u can have history of the cmds that run as crons which outputs on shell ; The o/p is lost if the shell is lost.

If we write them as logfiles ... u can revisit yr o/p again ...


Here is an example ... how to write into the logfile ...


exec >> ./logs/logfile 2>&1


echo `$TIME` "----------- TODAY IS `date` ---------------\n"
echo $PATH
echo "Hello ..."



Check the ./logs/logfile ... u get all echo outputs would be writen there.

I use more. Not that it matters all that much.

Code:
more file.log

Use the /<search pattern> to find words like Error, or whatever would indicate some sort of problem in a big log file.


However for large files or lots of files, grep is loads better -- if you know what word(s) indicate some sort of problem or error condition.
