Linux How To Append To A File
In Linux, you can append text to a file like this:
echo "This is a test." >> my_existing_file.txt echo "Another line of text." >> my_existing_file.txt
You can also redirect the output of an arbitrary command to a file like this:
ps -ef >> my_existing_file.txt
You can redirect multiple lines to a file like this.
cat >> my_existing_file.txt
After running this command you can type as many lines of input as you want. When you are done just type [CTRL]-D to stop reading. Everything entered will be appended to the file. See this example. “^D” represents where we typed [CTRL]-D.
cat >> my_existing_file.txt this is a test this is a test3 ^D
