1. Difference between instruction > and > >

Directive >: if the file exists, overwrite the contents of the original file; if the original file does not exist, create the file, and then add information.

Directive > >: the contents of the original file will not be overwritten and will be appended to the end of the file.

two。 Basic grammar (understand the difference between > and > >)

Basic syntax function description ls-l > filename list contents written to file ls-l > filename list contents appended to the end of file cat file 1 > file 2 overwrite the contents of file 1 to file 2 echo "contents" > filename write the contents to the file

3. Example:

Ls-l > filename:

Ls-l > > filename:

Other commands are similar. Without repeating it, you can verify it by yourself.
