Seems like that the /etc/inputrc file conforms to the shell script syntax. But the file name does not end with a .sh. The first line in the file does not have a #!, either.

Is it another kind of file?

And does that kind of file go in parallel with the .sh?

Does it run like a shell script?

Does it have a naming convention like the .sh suffix?

Yes, I understand that /etc/inputrc is one of the run control files together with /etc/profile, ~/.bashrc, and many many more. What I want to get clear is that is the inputrc one of, say, in Windows, .txt, .jpg, .docx, or anything like that. And does it have a specific syntax in contrast to the shell script. –  user43312 Jul 18 '13 at 11:14
    
Your model of file categories with a mandatory, well-defined suffix ("extension") for each category is simply inadequate, even in MS-DOS where they at least try to pretend that it kind of works. –  tripleee Jul 18 '13 at 16:12

/etc/inputrc is the system-wide configuration file for GNU readline, a library implementing a line editor used by many applications like gdb, python, GNU bc...

You can find documentation about it in the readline(3) man page or the official GNU readline documentation online.

readline is being maintained by the same person (Chet Ramey) as bash. bash and readline development have been closely tied. However, note that it's a modified version of readline that bash uses (but still reads /etc/inputrc and ~/.inputrc) since the generic readline library can't cover for all the needs of bash.

/etc/inputrc is just some configuration file. The name doesn't imply what the content or format may be. Others configuration file names follow the same pattern like netrc, screenrc, wgetrc... and the original meaning of rc (run commands) doesn't really apply there either. rc in those instances, should be seen as the same as .conf or .cfg. Those files in /etc that have a rc suffix often have a pendant as a dot file in the user's home directory (like ~/.bashrc, ~/.inputrc, ~/.screenrc). See also the Wikipedia page for more information.

The inputrc file handles keyboard mapping for specific situations. This file is the startup file used by Readline — the input-related library — used by Bash and most other shells.

Can I conclude that a startup file is another kind of file which goes similar to shell script? –  user43312 Jul 18 '13 at 11:10
    
It is not used by most other shells. bash comes with its own variant of readline. readline is being maintained by the same guy as bash. tcsh, zsh, ksh, fish, ash, yash do not use readline. The Linux ports of rc and es do. readline is used by countless non-shell applications though. –  Stéphane Chazelas Jul 18 '13 at 11:20
