20. August 2016 · Comments Off on Unixmen: Five lesser known tools · Categories: Information, Linux, Open Source Software

I just read an interesting article on Unixmen.com about some useful tools that are not widely known. All are interesting, and some are CLI while others are for a GUI environment.

I particularly like two of the CLI tools, iptraf to monitor TCP/IP traffic on your computer, and lsblk to list information about all block devices attached to a computer; that would usually be disk drives of all types. I particularly like the tree view that lsblk displays of not just the drives, but also the partitions on the drives.

Note that iptraf is now iptraf-ng in some distributions.

The following output displays the list of disk drives, including DVD-ROM and USB drives, as well as the hard drives and their partitions.

Typical output from the lsblk command.

Typical output from the lsblk -a command. In this case several different disk types are shown.

The information provided by the lsblk -a command as shown above contains data about hard drives and removable USB hard drives.  It also shows removable CD-DVD/ROM drives, sr0 and sr1. Disks sda, sdb, and sdc are all three regular hard drives. The sdd and sde devices are attached USB removable drives.

The man page contains detailed assistance for getting the most out of this command.

See the article for more information about the other tools.
