Ubuntu – Listing files in a directory including contents of subfolders with sorting

command linedirectoryfile sorting

I'm looking to list the entire contents of a directory, including the contents of subfolders but sorted by filesize.
Thus far I've managed to get as far as listing and sorting whilst still being recursive with ls -lhSR(the h is nice to have but definitely not essential for me, as long as I can get file sizes).
I am likely overlooking something obvious, or asking the impossible, but any advice here would be greatly appreciated.

You can use find:

find . -type f -printf "%s %P\n" | sort -n

Optional: To convert byte values to human-readable format, add this:

| numfmt --to=iec-i --field=1

Explanation:

 find in current directory (.) all files (-type f) 

 -printf: suppress normal output and print the following:
     %s - size in bytes
     %P - path to file
     \n - new line

 | sort -n: sort the result (-n = numeric)

Ubuntu – Listing files with grep

You don't need piping, grep or ls. Just use shell globbing.

In bash, using extglob pattern (should be enabled by default in interactive sessions, if not do shopt -s extglob to set it first):

file1@(|?|??)

? matched any single character, @(||) selects any of the patterns separated by |.

If you only meant to match any characters between a-z and A-Z, use use character class [:alpha:] which denotes all alphabetic characters in the current locale:

file1@(|[[:alpha:]]|[[:alpha:]][[:alpha:]])

Example:

$ ls -1
file1
file112
file11a
file12A2
file1a
file1ab
file1Ab
file1as
file2
fileadb

$ ls -1 file1@(|[[:alpha:]]|[[:alpha:]][[:alpha:]]))
file1
file1a
file1ab
file1Ab
file1as

zsh supports this natively:

file1(|[[:alpha:]]|[[:alpha:]][[:alpha:]])

I am answering this portion very reluctantly, upon request from OP.

Any future reader, Don't parse ls, use globbing.

Using ls and grep:

ls | grep -E '^file1[[:alpha:]]{,2}$'

Example:

% ls | grep -E '^file1[[:alpha:]]{,2}$'
file1
file1a
file1ab
file1Ab
file1as

Ubuntu – Listing modified files using a specific date range in a directory

You can try this

find -newerct "1 Sep 2016" ! -newerct "1 Oct 2016"

to see all files modified between 1th Sep 2016 to 1th Oct 2016. It works for find version equal or higher than 4.3.3

Here c is the inode status change time. You can also use m in place of it to have the result consider file modification time only.

Also the time string can be converted to YYYYMMDD format. So, 1 Sep 2016 becomes 20160901.
