How can I write and append using echo command to a file

I am trying to write a script which will use echo and write/append to a file. But I have " " in syntax already in strings .. say ..

echo "I am "Finding" difficult to write this to file" > file.txt
echo "I can "write" without double quotes" >> file.txt

Can anyone please help to understand this, really appreciated.

BR, SM

Solution

  • If you want to have quotes, then you must escape them using the backslash character.

    echo "I am \"Finding\" difficult to write this to file" > file.txt
echo "I can \"write\" without double quotes" >> file.txt

    The same holds true if you i.e. also want to write the \ itself, as it may cause side effects. So you have to use \\

    Another option would be to use The `'' instead of quotes.

    echo 'I am "Finding" difficult to write this to file' > file.txt
echo 'I can "write" without double quotes' >> file.txt

    However in this case variable substition doesn't work, so if you want to use variables you have to put them outside.

    echo "This is a test to write $PATH in my file" >> file.txt
echo 'This is a test to write '"$PATH"' in my file' >> file.txt
