Bash script for printing folder names and their sizes
Good day, everyone!
I'm very new to bash scripting. Our teacher gave us a task to create a script that basically does the same job the 'du' command does, with the difference that 'du' command gives an output in the form of
and what we need is
As for the moment, I came up with the following script:
Generally it does what it should, but is very-very slow. For example, on my '/usr' folder 'du' command (with everything before 'while' included) works for about 2 minutes and 30 seconds, while the script runs for 7 minutes and 20-30 seconds.
Is there a way to make it work faster? As I wrote before, I'm very new to scripting, so no doubt I'm missing something important.
How can I look at a certain directory and list all the file names, locations and sizes of each file in the current directory and all subdirectories? (2 Replies)

BASHBUG(1) General Commands Manual BASHBUG(1)NAME
bashbug - report a bug in bash
SYNOPSIS
bashbug [--version] [--help] [email-address]
DESCRIPTION
bashbug is a shell script to help the user compose and mail bug reports concerning bash in a standard format. bashbug invokes the editor
specified by the environment variable EDITOR on a temporary copy of the bug report format outline. The user must fill in the appropriate
fields and exit the editor. bashbug then mails the completed report to bug-bash@gnu.org, or email-address. If the report cannot be
mailed, it is saved in the file dead.bashbug in the invoking user's home directory.
The bug report format outline consists of several sections. The first section provides information about the machine, operating system,
the bash version, and the compilation environment. The second section should be filled in with a description of the bug. The third sec-
tion should be a description of how to reproduce the bug. The optional fourth section is for a proposed fix. Fixes are encouraged.
ENVIRONMENT
bashbug will utilize the following environment variables if they exist:
EDITOR Specifies the preferred editor. If EDITOR is not set, bashbug defaults to emacs.
HOME Directory in which the failed bug report is saved if the mail fails.
TMPDIR Directory in which to create temporary files and directories.
