Linux Version Help

Want to know which version your linux box is? Simple question isn't it...

Run the following commands:

cat /etc/*-release - This will give the distro of your linux

For Ex: for RHEL 5 it will give: Red Hat Enterprise Linux Server release 5 (Tikanga)

lsb_release -a - The lsb_release command displays certain LSB (Linux Standard Base) and distribution-specific information

For Ex: LSB Version: :core-3.1-ia32 Distributor ID: RedHatEnterpriseClient Description: Red Hat Enterprise Linux Client release 5.4 (Tikanga) Release: 5.4 Codename: Tikanga

uname -mrs - this will give you your kernel version

```
for ex: Linux 2.6.32-5-amd64 x86_64
```
where:

Linux - Kernel name
2.6.32-5-amd64 - Kernel version number
x86_64 - Machine hardware name (64 bit)

wget error–“zsh: parse error near &”

There is no doubt that I prefer wget way over any other type of downloads… Syntax: wget <DOWNLOAD_URL> If you get this error “ zsh: parse error near & ” then its probably because your download URL has a “&” so you should try giving your DOWNLOAD_URL in double quotes wget “<DOWNLOAD_URL>” If you are trying to download from a site which needs you to give your credentials then you can try giving it this way wget --http-user=<UserName> --http-password=<Password> “<DOWNLOAD_URL>” Hope this helps

Ubuntu: "Unlock login keyring" message "the password you use to log in your computer no longer matches that of your login keyring"

Resetting all the keyring passwords: Navigate to Places > Home . Press ctrl h t o view "hidden files". Navigate to .gnome2 > keyrings and delete login.keyring Using the same keyring (resetting keyring password but keeping old passwords in keyring): 1) Make a backup of the keyring cd ~/.local/share/keyrings/ cp login.keyring login.keyring.backup and after that delete login.keyring file rm ~/.local/share/keyrings/login.keyring 2) Create a new keyring file from Gnome Keyring with the name "login" 3) Replace the new keyring file with the backup of the old keyring file cd ~/.local/share/keyrings/ mv login.keyring.backup login.keyring Note: before Ubuntu 12.10 the path to the keyrings folder was ~/.gnome2/keyrings/ instead of ~/.local/share/keyrings/
