I wanted to do grep for keywords with double quotes inside. To give a simple example:
echo "member":"time" | grep -e "member\"" That does not match. How can I fix it?

Escaping. Generally, the backslash (\) character is yet another option to quash the inbuilt shell interpretation and tell the shell to accept the symbol literally.
' appearing in double quotes is escaped using a backslash. The backslash preceding the ' !
If you include special characters in patterns typed on the command line, escape them by enclosing them in single quotation marks to prevent inadvertent misinterpretation by the shell or command interpreter. To match a character that is special to grep –E, put a backslash ( \ ) in front of the character.
You cannot escape single quotes that appear within single quotes. As explained in the bash manual: Enclosing characters in single quotes (''') preserves the literal value of each character within the quotes. A single quote may not occur between single quotes, even when preceded by a backslash.
The problem is that you aren't correctly escaping the input string, try:
echo "\"member\":\"time\"" | grep -e "member\"" Alternatively, you can use unescaped double quotes within single quotes:
echo '"member":"time"' | grep -e 'member"' It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd').
