Description: | |
**entr** is a command line tool that let you run arbitrary command on | |
file change. This is useful when you are doing something that requires | |
some processing when you modify it. | |
Recently, I have used it to edit a man page. At first, I had to run | |
mandoc each time I modified to file to check the render. This was the | |
first time I edited a man page so I had to modify it a lot to get what | |
I wanted. I remembered about **entr** and this is how you use it: | |
$ ls stagit.1 | entr mandoc /_ | |
modified. The file names must be given by stdin to entr, and then use | |
the characters sequence **/_** to replace the names (like {} in find). | |
The man page of entr is very well documented if you need more | |
examples. |
