I have this command that does what I want but I can\'t get to alias it in my .bashrc (note that it uses both single and double quotes):

svn status | awk \'$1

    Here's something that accomplishes the same thing without using an alias. Put it in a function in your .bashrc:

    xx() {
        svn status | awk '$1 =="M"{print $2;}'
    }
    

    This way you don't have to worry about getting the quotes just right. This uses the exact same syntax you would at the command line.

    Since Bash 2.04 there is a third (easier) way beside using a function or escaping the way @ffledgling did: using string literal syntax (here is an excellent answer).

    So for example if you want to make an alias of this onliner it will end up being:

    alias snap-removedisabled=$'snap list --all | awk \'$5~"disabled"{print $1" --revision "$3}\' | xargs -rn3 snap remove'
    

    So you just have to add the $ in front of the string and escape the single quotes.

    This brings a shellcheck warning you could probably safely disable with # shellcheck disable=SC2139.

    You just need to escape it correctly.

    alias xxx="svn status | awk '\$1 ==\"M\"{print \$2;}'"
