Liping's playground

To dynamically  monitor NVIDIA GPU usage, here I introduce two methods:

method 1: use nvidia-smi

in your terminal, issue the following command:

$ watch -n 1 nvidia-smi

It will continually update the gpu usage info (every second, you can change the 1 to 2 or the time interval you want the usage info to be updated).

use Ctrl + C to terminate.

method 2: use the open source monitoring program glances with its GPU monitoring plugin

in your terminal, issue the following command to install glances with its GPU monitoring plugin

$ sudo pip install glances[gpu]

to launch it, in your terminal, issue the following command:

 $ sudo glances

Then you should see your GPU usage etc. It also monitors the CPU, disk IO, disk space, network, and a few other things

use Ctrl + C to terminate.

This post provides the instructions about how to unzip a file from terminal on Linux.

Step 1: install unzip using the following command

$ sudo apt-get install unzip

Step2: cd to the directory where you zip file located

Step3:  use  the following command to unzip your file

$ unzip yourfile.zip 

#this will unzip the file to the current folder

#if you'd like to extract to a particular destination folder, use the following instead:
$ unzip yourfile.zip -d destination_folder

This post will show you how to count files under a Linux directory.

Step 1: cd  to the folder you would like to count the files.

Step 2: issue the following command, then you should see a number, which is the number count of the files under the current directory.

find . -type f | wc -l

• -type f indicates  counting files only.   You can remove the -type f to include directories (and symlinks) while counting.
• | (note: not ¦) redirects find command’s standard output to wc command’s standard input.
• wc (stands for word count) counts newlines, words, and bytes on its input (see here for more details.).
• -l to count just newlines.

Notes:

• This command may overcount if filenames can contain newline characters.

This post tells you how to list files under a directory by time in reverser order and in human readable file size (works on Linux OS and Mac).

• ls -ltrh 

list all the csv files under the current directory in long format by time and in reverse order, the file size in human readable format (e.g., in mb, or gb, instead of byte size)

• -l List in long format. If the output is to a terminal, a total sum for all the file sizes is output on a line before the long listing.
• -r Reverse the order of the sort to get reverse lexicographical order or the oldest entries first (or largest files last, if combined with sort by size.
• -t Sort by time modified (most recently modified first) before sorting the operands by lexicographical order.

• ls -ltrh *.csv

list all the csv files under the current directory in long format by time and in reverse order, the file size in human readable format (e.g., in mb, or gb, instead of byte size)

From a terminal , issue the following command accordingly.

$ free          to see RAM information in KB.

$ free -m                 to see RAM information in MB.

$ free -g                o see RAM information in GB.

To check hard disk usage on Ubuntu from a terminal (command line), issue the following command  in your terminal.

liping:~$ df -h

-h stands for human which makes it readable by us humans, otherwise the file size will be in bytes:)

After you issue the command, you would  see your disk usage similar to the info given below.

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda7              68G   23G   43G  35% /
udev                   10M     0   10M   0% /dev
tmpfs                 800M  1.6M  798M   1% /run
tmpfs                 5.0M     0  5.0M   0% /run/lock
/dev/sda6             264G  173G   78G  69% /home
tmpfs                 3.2G  992K  3.2G   1% /tmp
