BASH - Redirection

Output Redirection

The '>' symbol is used for output (STDOUT) redirection.

ls -al > listings

Here the output of command ls -al is re-directed to file “listings” instead of your screen.

NOTE: Use the correct file name while redirecting command output to a file.

If there is an existing file with the same name, the redirected command will delete the contents of that file and then it may be overwritten.

If you do not want a file to be overwritten but want to add more content to an existing file, then you should use '»' operator.
