Full Discussion: Array copy in ksh

The return value of a function is a number, not a string.

One approach is to create your function (customise as you require) and pass the new array name to the function.

i.e.

Code:
$ cat ArrTest
GetDir() {
  cd $2
  ls -ltr | tail -$3 | while read FILE; do
    eval $1[\${#$1[@]}]="\$FILE"
  done
  cd - > /dev/null
}

# GetDir $1 is new array name, $2 is directory, $3 is the value for tail
GetDir A /tmp 5
echo A[0] is ${A[0]}
echo A[1] is ${A[1]}
echo
GetDir B /Users/scott 3
echo B[0] is ${B[0]}
echo B[1] is ${B[1]}


$ ./ArrTest
A[0] is drwx------ 3 scott wheel 102 5 Mar 20:49 launch-7Y8JI8
A[1] is drwx------ 3 scott wheel 102 5 Mar 20:49 launch-3RaSBo

B[0] is drwx------+ 79 scott staff 2686 26 Feb 20:54 Downloads
B[1] is drwxr-xr-x 34 scott staff 1156 5 Mar 00:33 scripts

Ksh array solution.

I was wondering if ksh supported arrays. I have a script that may work with several hosts. I'd like a means of knowing how many hosts I'm working with and an easy way to access them (as variables) in a loop. I'm assuming there's some kind of foreach in shell scripting. (1 Reply)

echo(3XCURSES)						  X/Open Curses Library Functions					    echo(3XCURSES)

NAME

       echo, noecho - enable/disable terminal echo

SYNOPSIS

       cc [ flag... ] file... -I /usr/xpg4/include  -L	/usr/xpg4/lib 
	-R  /usr/xpg4/lib  -lcurses  [ library... ]

       int echo(void);

DESCRIPTION

       The  echo()  function enables Echo mode for the current screen. The noecho() function disables Echo mode for the current screen. Initially,
       curses software echo mode is enabled and hardware echo mode of the tty driver is disabled. The echo() and noecho() functions control  soft-
       ware echo only. Hardware echo must remain disabled for the duration of the application, else the behavior is undefined.
