Bash Cookbook

How it works...

Whatever error message you get after pressing Enter, that error will get stored in log.txt. Now view the contents of log.txt as follows:

$ cat log.txt

So, in this way, you can avoid warnings as well as errors. Now, run the script as:

$ bash avoid_error.sh 2> log.txt

The error message will get stored in log.txt. You can view it by running the cat log.txt command.
