Command used #
df -hx tmpfs -x swap -x iso9660

why?
to exclude swap and iso9660 filesystem type.

what is required now?
Option1:
Is there a way wherein we give both the file system type with only one "-x" in the above given command?
Option2:
How to declare this as a variable in the beginning of the script? e.g. TYPE=iso9660,swap,tmpfs,etc.

I have followed all the instructions I have got from the net and made boot-able DVD's and USB sticks several different ways as people advise. I have done the same with Mint 17. I have created a partition (26G) and follow the install instructions 1: English 2:Has at least 7.4G available drive space. 4: Is connected to the internet. 5: Here it shows a page where I think it should display the drive options (but does not) If I push the "install now" button it comes up with an error "No root file system is defined --Please correct this from the partitioning menu" I close the installer and look at the drives in GParted and they are all there and the one I created for Linux is PARTITION - /dev/sda4 FILE SYSTEM - ext4
MOUNT POINT - /media/makulu/0C43086E0C43086E LABEL - Lin
SIZE - 26.02 GB USED - 590.07 Mb UNUSED - 24.44 GB FLAG - (blank)
No indication on how to fix the "No root file system" problem. I have tried so many bits of advise that I am beginning to think that I may be better of sticking to windows (perish the thought)
Can anyone help?

Looking at the /etc/shadow file, for some of the system services accounts there are "*" and for others "!!" in the password field.
Searching online I have only found that !=*, i.e. prevent use for log-in, but, if true, what is the actual difference? Why not use "*" on all of them? And why double exclamation point?

Hello, I hope someone can assist. I have installed 17 on 2 laptops and 17.1 on another all with windows 8 upgraded to 8.1 Now I have a new PC with 8.1 and cannot get 17.1 to install. I go thru all the steps but when I get past "something else" and choose the "free space" that I partitioned in windows and hit install the window pops up with "no root file system is defined" "Please correct from partitioning menu.. I have never had this happen, did I not do something? There is 1 300mb(fat32, efi) partition, ntfa, free space(which is where I am trying to install Linux), 1 small and 1 large "free space". Then the define for boot loader installation, which I do not remember needing to do before. Can someone please help. The PC is an Acer Aspire, amd10, 3.7ghz, quad core, radeon hd 8670 graphics , 1 terabyte hdd, 4gb ram, windows 8.1

Hello, I have an embedded linux device. I can connect to the device and I can upload or download files. No problem with this. But, at first connection, I want to connect to "/" directory instead of "/root". In the device file system, there are files ssh_config and sshd_config under /etc/ssh directory. I think I have to do something with these files but I don't know what.

I don't exactly know what mean "/root" and "/" directories. I think that the real root directory is "/" directory which is empty but when I connect with filezilla, the "/root" directory is the default so I had to go back to / directory everytime.

I am writing a script to check whether a "sysinfo" is installed in a system or not. sysinfo is a tool that gives information about the system. Its is installed in /usr/local/bin. so at CLI when I type sysinfo, it will display output.

#!/bin/bash
sysinfo=`/usr/local/bin/sysinfo`
echo "$sysinfo"
if [ "$?" = 0 ];then
echo "sysinfo installed"
else
echo "Please install sysinfo"
fi

Concept is, I run the command if it is present, it will show output and exit status of command is 0 else it is not installed. But it is not working as expected. Any thoughts , idea, suggestion.

Hi!

Hello,

I am trying to install OCI8. I'm pretty sure the last thing I need to do is run the "./configure" command, but no matter where I try to run it, it gives me back a "file not found" or "command not found" error. I have tried this on CentOS and Fedora and always install PHP with yum. I have done many GUI searches looking through the file system for "php" and have tried to run ./configure in every php folder I can find but the command never runs. Any suggestions are very much appreciated. Thanks so much!

-Matt

P.S. Do I even need to do this if I already edited the "php.ini" file and installed OCI8 with PECL? Thanks!
