This question already has an answer here:

This question is about ZSH, not bash.

I have the following lines in my .zshrc file. Whenever I open a terminal I get a no matches found error referencing the line with the if statement.

if [[!( -a ~/.zkbd/$TERM-${${DISPLAY:t}:-$VENDOR-$OSTYPE} )]]; then

I read through the ZSH documentation and my if statement appears to be correct. I don't understand why I'm getting the error.

What I'd like to happen is for the zkbd utility to run if the file in the .zkbd folder does not exist.

    @Gilles, how is that a duplicate? OK, in both cases, adding spaces fixes the problem, but considering as duplicates any question where the solution is to add spaces somewhere sounds wrong to me. – Stéphane Chazelas Aug 24 '15 at 13:09
  • @StéphaneChazelas How are they not duplicates? Both are asking why [ … ] doesn't work without spaces inside. – Gilles Aug 24 '15 at 13:13

    @Gilles, one is about the [ command, the other one about the [[...]] construct, one is about bash, the other one is about zsh. The error messages are completely different (at least it would make sense to explain why you get a no-match error in zsh here). – Stéphane Chazelas Aug 24 '15 at 13:19

    @Gilles, also note that all of bash, ksh93 and mksh do support [[(a == b)]] (not [[!(a == b)]]), not zsh. – Stéphane Chazelas Aug 24 '15 at 13:35

Thanks to don_crissti for answering this for me.

The correct if block is below.

if [[ ! -a ~/.zkbd/$TERM-${${DISPLAY:t}:-$VENDOR-$OSTYPE} ]]; then

    for ADHD people like me, the solution is [[ -a FILE_NAME ]], the "! -a" asks if the file does not exist. – azorius Feb 9 '17 at 7:47

    @azorius My initial question was asking how to test if a file does not exist. – Dave F May 11 '17 at 17:27
