I have a strange issue.
There is file on which:
$ cat fp_id_led
1
$ echo 0 > fp_id_led
$ cat fp_id_led
1 <--- Still shows 1!
Also when I open the file in vim its just empty.
How can I flip that value in the file.
Probably the file is located not on a normal filesystem, but on a pseudo filesystem, like /proc?

Is there a easy way to list all open named pipes on linux? O a bash command to show all open named pipes?
An option: you can use the lsof command line tool: https://www.simplehelp.net/2010/04/09/how-to-get-a-list-of-open-files-sockets-and-pipes-in-linux/

I have used a command called 'cat /etc/group' what does this command mean and do.Can you tell me what each part of the command does please use simple terms.
You can find the answer to your question explained better than any of us ever could with this command:
man cat
It prints to standard output the contents of the file at the location /etc/group
Ok so cat outputs the file, which (in your case) contains basic info about groups.
If you are interested in what are the groups just click here

I'm running Linux Mint 14 and accidentally replaced the contents of /etc/environment file. It was originally something like:
PATH=/usr/bin
but with some extra stuff. At the moment, most commands don't work in the terminal. If I do "ls", I get "command not found". Does anyone know the standard contents of this file is?
On ubuntu 12.04 it is:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

How to delete folders using single line command irrespective of whether the folder is empty or non-empty?.. Any idea?
The rm(1) command has the flag -r for that. You should not use the -f flag with this command, unless you know what you are doing, as placing a wrong * or space can have you deleting a lot more than you intended.
