Everything: the fastest file name search tool (for Linux)

ArticleThe name is used to make good use of the software. everything is a quick search tool for Windows. it is basically not used in Linux. I have been using gnome-do, and I feel it is okay. thisProgramIt is only used to practice wxpython. Currently, it is only a very simple version. of course, the backend uses mlocate. in Linux, the search principle is basically the same as that in everything, but the command line is used. I just wrote a front-end GUI.

Below is the preliminaryCode.
