Kuidas erinevad üks suurem märk (>) ja kaks suuremat märki (>>) faili kirjutamisel?

In the context of writing to a file (for example, in the Linux command line), the angle bracket > and the double angle brackets >> perform different functions:

• > — redirects the output of a command to a file, overwriting the file's contents. If the file exists, its contents will be deleted and replaced with the new output.

• >> — redirects the output of a command to a file, appending data to the end of the file. If the file exists, the new data will be added after the current contents.

Example:

# Overwrite the file output.txt
echo "Hello" > output.txt

# Add a line to the end of output.txt
echo "World" >> output.txt

After executing these commands, the file output.txt will contain:

Hello
World

Thus, > is used for creating or replacing a file, and >> for adding to an existing file.
