This repo contains daily tools used to automate work.
song_converter.sh will use pacpl to extract video' audio from mp4 file and store it in mp3 format.
This script takes a normal command, in any form, and discard all its output, then makes it run in the background.
This script will convert markdown format file into html using pandoc. Only one file is allowed. Output will assume to replace the suffix of the file.
This script will change the privilege of files and folders under the folder given into a safe mode. No one except yourself could access to them.
This script could merge multiple pdf files into one, with order the same with the order you list the files in the command line.
This script could extract any range of pages from PDF.
The script converts document from djvu format to pdf format. The most important feature is that it keeps the text layer of djvu file so you could highlight text in your new pdf! This is very important for serious reading of books.
Note that no space is allowed in the book's file name(I did not figure out a elegant way to handle it. If anyone knows, it is great to let me know).
