rsync

I was using rsync -e "ssh" to transfer files between local and remote computer. If I want to transfer a file from remote to local, the command will be like rsync -av --delete -e "ssh" user@ip:/path/to/fileA /home/user/folder/. One day, however, I thought I could transfer a remote folder /path/to/folderA/ to my home /home/user/. After running the command, I found that it started erasing my home directory! Since Linux has disk encryption by default, I failed to rescue those files eventually ;(

bash_history

My bash history was stored as ~/.bash_history. One day, I was running a huge apt upgrade. It took me plenty of time, so I left it and went to sleep. However, I forgot that my laptop was in battery mode. So eventually, the battery ran out, and my computer experienced an abnormal power off, which resulted in me having a corrupted bash_history. I have no backups, so I lost all my bash history ;(

tee

I just learned how to use tee to app

Generate mappings from a language to its corresponding script name and
dependencies for highlight.js. Tool written by davidhcefx, 2020.8.24.

In highlight.js, we highlight codes via <pre><code class="language"></code></pre>
However, what is the corresponding JS script name for a specific language?
What are the dependencies, if any, in order to use that language?
This tool aims to build the relationships by parsing the source files.

help - IPython Custom Magic Command

If you are a command-line lover, then it is likely that ipython is already one of your friend. In Python, help() is our swiss army knife. However, always having to embrace commands with parathesis, ( and ), is really a hassle! Wouldn't it be great if we could simply invoke like this?
