A Brief Intro
Sometime ago, someone posted a tweet about a replacement for
rm -rf $HOME/directory that is mv $HOME/directory /dev/null. When i took
a look of it, using the ls -l /dev/null command, i found something like this:
crw-rw-rw- 1 root root 1, 3 Jun 11 04:21 /dev/null
Now, what is c in the crw below
crw-rw-rw- 1 root root 1, 3 Jun 11 04:21 /dev/null
After going around on internet, i found an answer in stackexchange1. Which
explain that c stands for character special file. Please keep in mind that
everything in unix-like system is a file, even a directory (or some people
called it folder) is a file with type directory.
The file we usually use has a type of
regular file.
In the stackexchange, someone mentioned about info ls to show the file type
with their respective character symbol. That’s what pique my interest, the
info command.
Replacement For info Command
When i use the command info ls, i noticed that i can’t use j and k for
navigation, which is a nightmare.
So, the first thing that i need to figure out is, how to change the pager used
in info command. According to this stackexchange answer2,
“info doesn’t use separate pager because it handles navigation”. So,
basically there’s no hope with info command? Probably.
And then, the person who answer on the stackexchange also give a suggestion
about pinfo which, at least use j and k as down or up movement. Now i
need to read the manpage about pinfo to configure it.
What’s Next?
Other than trying to configure pinfo, i might need to figure out what is the
info documents is all about. This might be a new kind of documentation other
than manpage that i can use (if the developer support it). Also, figure out
about the character special file type.
