Deleting a linux file with spaces

It is a common issue and can be found on many blogsites how to delete a file/s with spaces. But I want to share my own version. The solution for this problem is to use a quotation mark "" (quotes), backslash or the tab key.

Trying to create a file:
#touch filename test 1
# ls -al
total 24
drwxr-xr-x 2 root root 4096 Nov 29 23:17 .
drwxr-x--- 38 root root 16384 Nov 29 23:17 ..
-rw-r--r-- 1 root root 0 Nov 29 23:17 1
-rw-r--r-- 1 root root 0 Nov 29 23:17 filename
-rw-r--r-- 1 root root 0 Nov 29 23:17 test

Using quotes:
#touch "filename test 1"
#ls -al
total 24
drwxr-xr-x 2 root root 4096 Nov 29 23:20 .
drwxr-x--- 38 root root 16384 Nov 29 23:17 ..
-rw-r--r-- 1 root root 0 Nov 29 23:20 filename test 1

Listing file/s with spaces:
#ls -la filename test 1
ls: filename: No such file or directory
ls: test: No such file or directory
ls: 1: No such file or directory

Listing file/s with quotes and backslash:
#ls -la "filename test 1"
-rw-r--r-- 1 root root 0 Nov 29 23:20 filename test 1

or

# ls -la filename\ test\ 1
-rw-r--r-- 1 root root 0 Nov 29 23:20 filename test

or using the tab button
#ls -al filename
then hit TAB key and all filename* will show up and type the next character

Removing file without quotes
# rm filename test 1
rm: cannot lstat `filename': No such file or directory
rm: cannot lstat `test': No such file or directory
rm: cannot lstat `1': No such file or directory

Using quotes in removing file with spaces:
# rm "filename test 1"
rm: remove regular empty file `filename test 1'? y

Moving/ Renaming directory w/o quotes
# ls -la
total 28
drwxr-xr-x 3 root root 4096 Nov 29 23:32 .
drwxr-x--- 38 root root 16384 Nov 29 23:17 ..
drwxr-xr-x 2 root root 4096 Nov 29 23:29 folder test 1
Note: folder test 1 is a directory

#mv folder test 1 foldertest1
mv: target `foldertest1' is not a directory

Using quotes:
# mv "folder test 1" foldertest1
# ls -la
total 28
drwxr-xr-x 3 root root 4096 Nov 29 23:34 .
drwxr-x--- 38 root root 16384 Nov 29 23:17 ..
drwxr-xr-x 2 root root 4096 Nov 29 23:29 foldertest1

or Using the backslash

# mv folder\ test\ 2 foldertest2
# ls -la
total 28
drwxr-xr-x 3 root root 4096 Nov 29 23:36 .
drwxr-x--- 38 root root 16384 Nov 29 23:17 ..
drwxr-xr-x 2 root root 4096 Nov 29 23:29 foldertest2


Deleting directory with quotes
# rm -rf "folder test 2"
# ls -la
total 24
drwxr-xr-x 2 root root 4096 Nov 29 23:38 .
drwxr-x--- 38 root root 16384 Nov 29 23:17 ..

Fedora Core 8 - Insight

The much awaited Fedora Core 8 was final released on 08 Nov 2007. The version8 named "WEREWOLF"

    "Werewolf" moves across the land
    Router meltdowns close at hand
    Sysadmins in search of blood
    For those who caused this bandwidth flood
    And whosoever took the risk
    But failed to make an extra disc
    Must face the Bastard Op from Hell
    And lose his access to the shell


    The best of Linux now is here
    To kill the FUD and strike with fear
    The hearts of those who steal your rights
    And hide their code far from your sight
    Closed source takes away what's yours
    But you'll never shake the horror
    Until you taste the freedom and
    The power of FEDORA!

For Screenshoots Installation: Click this link


After the released of FC8, you opt to know those common bugs while installing, configuring and maintaining your desktop hardwares and softwares where bugs are on their ways.

Common Issues

CD/DVD Install Hangs

There appears to be an issue between ISOLINUX and certain BIOSes where the USB keyboard does not work at the boot menu. This can be worked around by holding down the "shift" key during bootup to force the bootloader into text mode.

Bug 239585 - On certain systems, the CD/DVD may hang during boot with message "Ready". Most of the bugs that caused this are thought to be fixed, though on some systems adding "edd=skipmbr" to the kernel command line, works around this issue.

Upgrade Hang

Bug 372011 - Anaconda hangs in postselection in Fedora 7 to Fedora 8 upgrade. This problem is still being investigated.

Sun Java Bug

Bug 254144 Fedora 8 includes IcedTea, a free and open source derivative of OpenJDK. Users trying to install Sun Java might run across a bug with the Sun JVM that makes it incompatible with the newer libX11 included in Fedora 8. Workaround is documented. We highly recommend using IcedTea instead.

Suspend/Resume Problem With Nvidia cards

Suspend option in the menu has been deliberately disabled in this release on systems with Nvidia cards since the default "nv" Xorg driver from Nvidia has a number of problems in handling of suspend and resume correctly. If you wish to override this default, add a file that contains ALLOW_NV_SUSPEND="yes" under /etc/pm/config.d

NetworkManager cannot connect to EAP-TLS secured wireless networks

Bug 323371 - The NetworkManager 0.7 snapshot included in Fedora 8 cannot connect to networks that use encrypted certificate files for authentication. A fix will be available soon.

NetworkManager fails to see wireless networks with Intel 3945 chipsets

Bug 319071 If you have the Intel 3945 wireless chipset, you may experience trouble finding and associating with wireless networks in NetworkManager. Try adding

options iwl3945 disable_hw_scan=1

to /etc/modprobe.conf

Cannot start ssh: Service will not start after installation of the x86_64 version

Bug 364971 - /usr/sbin/sshd: Permission denied

This issue should be fixed by updating to the latest selinux-targeted-policy which is greater than selinux-policy-targeted-3.0.8-44.fc8

Package Updater (PUP) is asking to insert CD

Bug 381721 - In a fresh F8 DVD install, you might see Package Updater (PUP) is asking to insert CD when you launch it for the first time. As a work-around, click on Repository Manager and uncheck "Install Media". See a screenshot.

Booting Installer on Dell Notebooks

Using boot.iso the install hangs during the initial boot at the following:

running install...
running /sbin/loader

Try adding

nohz=off nolapic

to the kernel line.

Less Common Issues

Help viewer crashes when searching

Bug 361041 - yelp (the GNOME Help Browser) may crash when you use its search box. This happens on systems where virt-manager is installed, due to a bug exposed by a bad help file in the virt-manager package. Bug 361071 tracks the bad help file.

This is fixed in yelp-2.20.0-5.fc8, which is available as an update.

Change in behavior: Partition table claimed to be invalid on previously working drive

Bug 241288 - Prior to Fedora 7, the host protected area of hard drives was often ignored and formatted as usable drive space. Starting with Fedora 7 and the new libata driver subsystem, the host protected area is respected by default. As a result, its possible the Fedora 8 kernels will believe your drive has a partition that extends off the end of the disk, as the sectors of the hpa are masked out. The work-around to upgrade such systems is to pass the module parameter 'libata.ignore_hpa=1' when booting the installer. For example, when booting the installer cd, boot with:

boot: linux libata.ignore_hpa=1

Those upgrading from FC6 or earlier via yum on impacted systems can add a line to modprobe.conf along these same lines to allow an F8 kernel to boot their system. Ex:

options libata ignore_hpa=1

Upgrade fails when using SELinux strict policy

Bug 369611 - Machines using the SELinux strict policy (selinux-policy-strict package) cannot upgrade because the new consolidated selinux-policy-targeted package does not properly obsolete the old strict package. To upgrade, first remove the strict policy using the command rpm -e selinux-policy-strict.

Note: I will install FC8 later and I will definitely post some of the bug fixes.

Fedora Linux Installation Howto

Fedora Installation (Screenshots)

1. To get started, insert the first installation CD (or the DVD), and power on the machine. Assuming your system boots normally, the first screen you should see contains a couple of installation options. You can install Fedora in either graphical mode, or in text mode. Text mode is useful if your having trouble working with the your system's graphics adapter.
2.Regardless of which mode you choose for installation,the next screen is a text screen that asks if you want to test your CD media before you install. If you have new disc,skip this section and click next. This test makes sure the installer will be able to read everything
it needs to properly install.
3. The graphical installation begins. Choose your language and click the Next button.
4.If you're using a new disk or want to format your hard disk. Answer Yes to initialize the disk. 5.Partitioning your drive, fedora provides a default layout which I have chosen for this installation. If you choose to remove partitions and create new ones, Anaconda pops up a warning that indicates that all data will be lost on the partitions you remove.
6. I've provided a screenshot that shows you the default disk layout for this operating system. In short,on this 16 GB disk, I have a 1 GB swap partition and a single 15 GB volume (named "/").
7. Use a boot loader for your new installation which is GRUB by default so that you can easily make changes the way your system boots especially in booting other operating systems if necessary.
8. If you want to manually provide TCP/IP addressing information, click the Edit button to bring up the window on which you can provide an address, subnet mask, gateway and dns address.
9. Select your time zone from the list.
10.Provide the password for the "root" user.
11.Choose what kind of software you want to make available on your new desktop system,for manual selection click "Customize now". This process can be done at any time, even after the initial installation of the system.
12. The formatting begins and immediately starts the process of installing the operating system and packages you've selected.
14. When installation done. Reboot the system and wait to boot GUI of your newly installed fedora. Good luck!

WINE (WINdows Emulator)

Wine is an Open Source implementation of the Windows API on top of X, OpenGL, and Unix.
Think of Wine as a compatibility layer for running Windows programs. Wine does not require Microsoft Windows, as it is a completely free alternative implementation of the Windows API consisting of 100% non-Microsoft code, however Wine can optionally use native Windows DLLs if they are available. Wine provides both a development toolkit for porting Windows source code to Unix as well as a program loader, allowing many unmodified Windows programs to run on x86-based Unixes, including Linux, FreeBSD, Mac OS X, and Solaris. For more... http://www.winehq.org/

One way of installing wine: using linux command prompt (root access)
1. #yum install wine* it will then install wine and all its required libraries
2. Wine has its own C:/ directory and program files to keep your installed software under
Menu > Wine > Wine File

Then, I followed the documentation on the site for configuring wine. http://www.winehq.org/docs/en/wineusr-guide.html#CONFIG-WINE-MAIN

see wine website for other detailed info.
