I have different data which were created at different date and time shown below.

I hope to show the last column which are file names with suffix .lammpstrj. If I use
`ls -latr *.lammpstrj | cut -d ' ' -f 9`
I cannot get all file names. I noticed that the multiple spaces between month and day led to such problems. Any universal solution for cases similar to this one? I sincerely appreciate your time and help.
If you just want to view them: ls -1 *.lammpstrj
If you want to iterate over them: for file in *.lammpstrj; do ...
If you want to store them for later use:
files=(*.lammpstrj)
# now do stuff with them, for example print them:
printf "%s\n" "${files[@]}"
# or something else
for file in "${files[@]}"; do ...
To get metadata about your files, use stat:
stat -c "%Y %s %n" *.lammpstrj | while read -r mtime size filename; do
printf "%s has size %d and was last modified %s\n" \
"$filename" \
"$size" \
"$(date -d "@$mtime" "+%Y-%m-%d %H:%M:%S")"
done
Or use -printf in find
