Write into .log file

Question

I'm making a script and every time something is done I would like to write into my custom .log file. How do I do that?

And in the end.. I'd just like to read it with Bash,.. do I just use cat?

Thanks.

sure, you can just use "echo" and/or redirect output using > and >> to a file. — hovanessyan

Nothing wrong with this question. Why the downvotes? If you downvote, please clarify. Even more if against a low-scored user that needs incentive, not downvotes. — DrBeco

The simplest syntax I always use is 2>&1 | tee -a file_name.log.

The syntax can be used after a command or execution of a file. e.g.

find . -type f 2>&1 | tee -a file_name.log

or

./test.sh 2>&1 | tee -a file_name.log

Just cat <log message here> >> custom.log.

The >> means add on to the bottom of the file rather than > which would delete the contents of the file and then write the message.
