It looks to me like there is no single expression that can be used to get just the list of all the elements that match an expression from an array. It seems like you need to iterate over the elements of an array via an expression like: #the_word is $words[CURRENT-1] cnt=2 words=() while [[ $historywords[(in:cnt:)the_word] -lt $#historywords ]] ; do words=($words $historywords[$historywords[(in:cnt:)the_word]-1] let "cnt = cnt + 1" done Is there a faster way to do this? I'd like to do this with a large historywords (currently I have 4728 elements) doing this takes between 1 and 2 seconds. If I copy historywords to a temporary array to do the search it goes much faster. But if the search could be done in one operation, it would be faster and wouldn't require a temporary copy of historywords. Would anyone object to a new special parameter (maybe historywordsnums) that has corresponding elements to historywords saying with which history line the word is associated? I ask since one of the problems with this completer is that it picks up false "matches" when the previous word is the last word of a previous command, it gets the next command. It would be nice to be able to determine if a word is the last word of the line, or what the first word of the line is. -FR. __________________________________________________ Do You Yahoo!?
