Very useful Linux tips and tricks for the terminal user

Very good find command trick

Find all files on your system changed since a certain date.

ubuntu ~ $ sudo find . -type f -newermt 2017-04-25
./.local/share/mc/history
./.local/share/mc/filepos
./.cache/mc/Tree
./uptime.py
./.config/mc/ini
./.viminfo
./.bash_history

Install a very nice slim desktop on Linux Mint and Ubuntu

jason@jason-virtual-machine ~ $ sudo apt install i3 lxdm lxappearance pcmanfm gnome-themes-standard breeze-icon-theme

Then logout of the desktop and press Control-Alt-F2 to get to a virtual terminal. Login and type sudo service mdm stop. Then start lxdm with this command: sudo service lxdm start.

Now the Linux Mint distribution has a nice, fast desktop interface.

Set a locale on a Debian system

The locale on a Debian system is set via the /etc/locale.gen file. I un-commented the locale I needed, then I ran the locale-gen command as root to generate a locale for the system.

This is very easy to do.

The shopt command in bash will show shell options. Just use the shopt built-in command to list all of the available shell options.

To set an option, do it like this.

ubuntu ~ $ shopt -s mailwarn

This turns the mail warning on.

Turn if off again like this.

ubuntu ~ $ shopt -u mailwarn

List only directories in a directory listing with ls

The ls command may be used to list only directories. This is very easy.

ubuntu ~ $ ls -la -d */
drwxrwxr-x 2 ubuntu ubuntu 4096 Jun 10  2016 boards.4chan.org/
drwxr-xr-x 2 ubuntu ubuntu 4096 Nov  3  2015 crunch-3.6/
drwxrwxr-x 5 ubuntu ubuntu 4096 Apr 27 23:47 Documents/
drwxr-xr-x 3 ubuntu ubuntu 4096 Mar  5  2016 easy-rsa/

drwxrwxr-x 5 ubuntu ubuntu 4096 May 16  2016 ipinfo/
drwxrwxr-x 5 ubuntu ubuntu 4096 Oct 31  2016 jail/
drwxrwxr-x 2 ubuntu ubuntu 4096 May 29  2015 keys/
drwxrwxr-x 3 ubuntu ubuntu 4096 May 14  2015 nt/
drwxrwxr-x 2 ubuntu ubuntu 4096 Feb 20  2015 openvpn/

drwxrwxr-x 7 ubuntu ubuntu 4096 Mar 13  2015 wpscanteam-wpscan-aed74e0/

The ls -la -d */ command is very useful for this.
