Can I assign the contents of file into an array?

murtaza · #1 (**permalink**) 03-27-2007

I am trying to assign the contents of file e.g

ls "$HOME"

into an array. If it is possible then please guide me without using the concept of awk,sed, and perl16

Thanks

set -A arr `ls"$HOME"`

pls paste here the error message and the task you want to do.what you want to do either assign contents of file to an array or the result of ls command to array.

I just want the result for ls command to array. Thanks for interest

ds: line 4: set: -A: invalid option
set: usage: set [--abefhkmnptuvxBCHP] [-o option] [arg ...]

Do you have korn shell ksh or you are running into some other shell.
pls switch it to korn shell to use arrays.

Code:

#!/usr/bin/ksh
x=`ls skm`
echo $x
set -A look $x
echo ${look[0]}

You can do it without "ls":

Code:

$ ls
a  b  c
$ set *
$ echo ${1} # first element
a
$ echo ${2} # second
b
$ echo ${@} # all
a b c
$ echo ${#@} # number of elements
3
$ eval echo \${${#@}} # last element
c
