bash alias command with both single and double quotes

Question

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 =="M"{print $2;}'

I've tried:

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

And some other common sense combinations with no luck.. I know that bash is very picky with quotes.. So what's the correct way to alias it and why ? Thanks

Answer 1

You just need to escape it correctly.

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

Answer 2

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.

Answer 3

There is a third way (I found easier) beside using a function or escaping the way @ffledgling did: using string literal syntax (here is an excellent answer).

So for example if you wan't 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.
