![stack overflow question, semi-screen reader friendly. the text reads:
I'm trying to store the files listing into an array and then loop through the array again. Below is what I get when I run ls -ls command from the console.
```
total 40
[lists two files, with a list of properties]
```
The following bash script I've written to store the above data into a bash array.
```
i=0
ls -ls | while read line
do
array[ $i ]="$line"
(( i++ ))
done
```
But when I `echo $array`, I get nothing!
FYI, I run the script this way: `./bashscript.sh`](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:tiqo54hrm5ju3npdoqmv2isg/bafkreif2yz3yil4ijm4s4nkzuj627nz5cpucsysok4i4fnnhwsfeksts3m)
![Try with:
```
#! /bin/bash
i=0
while read line
do
array[ $i ]="$line"
(( i++ ))
done < <(ls -ls)
echo ${array[1]}
```](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:tiqo54hrm5ju3npdoqmv2isg/bafkreig2min6e2riukmmk62q2o4dyb7d4ofrazn4g4njh4uizfkix3wh7i)
![Here's a variant that lets you use a regex pattern for initial filtering, change the regex to be get the filtering you desire.
```
files=($(find -E . -type f -regex "^.*$"))
for item in ${files[*]}
do
printf " %s\n" $item
done
```](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:tiqo54hrm5ju3npdoqmv2isg/bafkreiakiziase67cpuq6vrlvhun7fbzsxaomfysc5e3tilxhmtktnc7um)
![Full bash sample
```
#!/bin/bash
declare -a bydate=() bysize=() byname=() details=()
declare -i cnt=0 vtotblk=0 totblk
{
read -r _ totblk # ignore 1st line
while read -r blk perm lnk usr grp sze date file;do
byname[cnt]="${file//\\ / }"
details[cnt]="$blk $perm $lnk $usr $grp $sze $date"
bysize[sze]+="$cnt "
bydate[${date/.}]+="$cnt "
cnt+=1 vtotblk+=blk
done
} < <(LANG=C LC_ALL=C /bin/ls -lsb --time-style='+%s.%N')
```
From there, you could easily sort by dates, sizes of names (sorted by `ls` command).
```
echo "Path '$PWD': Total: $vtotblk, sorted by dates"
for dte in ${!bydate[@]};do
printf -v msec %.3f .${dte: -9}
for idx in ${bydate[dte]};do
read -r blk perm lnk usr grp sze date <<<"${details[idx]}"
printf ' %11d %(%a %d %b %T)T%s %s\n' \
$sze "${date%.*}" ${msec#0} "${byname[idx]}"
done
done
echo "Path '$PWD': Total: $vtotblk, sorted by sizes"
for sze in ${!bysize[@]};do
for idx in ${bysize[sze]};do
read -r blk perm lnk usr grp sze date <<<"${details[idx]}"
printf -v msec %.3f .${date#*.}
printf ' %11d %(%a %d %b %T)T%s %s\n' \
$sze "${date%.*}" ${msec#0} "${byname[idx]}"
done
done
echo "Path '$PWD': Total: $vtotblk, sorted by names"
for((idx=0;idx<cnt;idx++));{
read -r blk perm lnk usr grp sze date <<<"${details[idx]}"
printf -v msec %.3f .${date#*.}
printf ' %11d %(%a %d %b %T)T%s %s\n' \
$sze "${date%.*}" ${msec#0} "${byname[idx]}"
}
