file names in arrays

file names in arrays

[zzapper]

Hi,
At the risk of being abused, RTFM etc etc

Has anyone got a script where a number of file names resulting from say a find/grep are loaded into
an array.

And then this array is looped thru with a promt deciding what might happen to these files, mv,rm,cp
edit etc

a=(${(ps:\0:)"$(find /path -print0)"})
for i in $a
do
  while :
  do
    print -n "Frob $i? (y/n) "
    read r
    case $r in
      ([yY]) frob $i; break;;
      ([nN]) break;;
      (*)    print "invalid input";;
    esac
  done
done

You get the idea...
Phil.

Go to http://www.zsh.org/cgi-bin/mla/wilma/users and search for "keeper".

Isn't the answer to this the same as -- or awfully similar to, at any
rate -- the answer to your "Creating a Case statement dynamically" 
thread from a couple of days earlier?


    local file command target
    find "$@" | keep
    for file in $kept
    do
	PS3="Action on $file: "
	target=''
	select command in mv cp rm gvim
	do
	    case $REPLY in
	    ((Q|q)*) break 2;;
	    (<1->) 
		case $command in
		(cp|mv) vared -e -p "$command $file " target &&
			[[ -n $target ]] && $command $file $target
		(?*) $command $file;;
		(*) break;;
		esac;;
	    (*) break;;
	    esac
	done
    done

Bart,
Yes it's similar to my previous thread, but hopefully more general. I'd found a useful solution, but
didn't use arrays, so I ended up repeating operations.
Your script above blows up for me on

pick3:17: parse error near `$command' (the vared line)

zsh 4.2.4 (i686-pc-cygwin)

Bart,
And I was looking for some complex bug, and failed to spot the obvious

Bart,
I may combine your script with that of Phillipe as Select had two disadvantages in this case (it
uses numerics, whereas I'd prefer the menonmic v for vi c for cp m for mv etc, also because select
automatically repeats on an empty return, whereas I want it to goto next. Nevertheless your script
is a mini-tutorial in scripting
