Bash redirect and add to nonexistent file / directory

When i use >> nonexistent/file.log. Bash returns to me "There is no such file or directory."

How can I create one liner that redirects STDOUT / STDERR to a log file, even if it does not exist? If it does not exist, it must create the necessary folders and files.

You can use dirnameto get the base path to the file and then use it with mkdir -p. After that, you can redirect:

sh mkdir -p `dirname nonexistent/file.log` echo blah >> nonexistent/file.log

if [ ! -d ~/nonexistent ]
  then mkdir ~/nonexistent
fi

Then use the other examples provided to simply copy the resulting file created with ls, back to the host field in the newly created directory.

To automatically generate all directories for a file path:

FILEPATH="/folder1/folder2/myfile.txt"
if [ ! -f "$FILEPATH" ]; then
    mkdir -p "$FILEPATH"
    rm -r "$FILEPATH"
fi
#/folder1/folder2 has now been created.
