BASH arrays

[c0mput3r_n3rD]

Hello,
I'm writing a script that makes a link of all the files in the pwd, and puts the links in another directory. For this I want to put the values of the ls command into an array, and then I can step through the array using a for loop. Can any one help with storing the values of the ls command in an array?

thanks

i=0
while read line;
do
files[i++]=$line;
done < <(ls)


for (( i = 0 ; i < ${#files[@]} ; i++ ))
do
echo ${files[$i]}
done


wouldn't it be easier to do it in one step for such a simple task?

i=0
while read line;
do
files[i++]=$line;
done < <(ls)

That's asking for user input.

I'm looking for more of a :


myArray='ls'

type of thing

yes it stores everything ls lists in an arry
for only files modifiy the ls command (e.g. ls -1 | grep -v ^d)
works on my machine
GNU bash, version 3.2.48(1)-release (i486-pc-linux-gnu)

[c0mput3r_n3rD]

i=0
while read line;
do
files[i++]=$line;
done < <(ls)
will get everything ls lists, and then i can use the for loop to step through the array that was created?

oh right:


IFS=$'\n'
files=(`ls -1`)
unset IFS

is a much easier solution :)

IFS change so it handles spaces correctly

Awsome! Thank you very much :D

[MadCow108]

the unset IFS may be problematic when you need it again
better:


bac=$IFS
IFS=$'\n'
files=(`ls -1`)
IFS=$bac

you don't need arrays for this


find /path -type f | while read FILE
do
#do your stuff with $FILE
done

I'm just learning arrays, but it was mentioned in another thread that you can create an array as in the following:


array=( * ) ; for f in "${array[@]}" ; do echo "$f" ; done

Is it necessary to use ls?

no need.
