You can append a line of text to a file by using the >> operator:

echo "hello world" >> my_file.txt

or in your case

echo "alias list='ls -cl --group-directories-first'" >> config.fish

Please take note of the different types of quotes.

I use echo myself, but be careful, if you only specify one > then the file will truncate, not append. for a safer command you can use sed: sed -i '$a hello world' filename – invert Jan 25 '11 at 8:05

explanation: -i will update the file (otherwise it will just print the result to stdout), $ is regex that will match the end of the file, and a appends the following text to filename. – invert Jan 25 '11 at 8:08
It sounds a bit bit, like there's an echo cho in this statement ment. Nice ice. – McGafter Feb 8 at 15:16
