Jun 8, 2015 - Green Console on CodeAnywhere

Comments

Well I’m fanatic of my green terminal, and for now I use a lot codenaywhere.com. Is a web IDE online, and you can create devbox, like a vps. Everything works great but I miss my green console. and I use this simple line of jQuery to edit the font color. Is cool anyway =)

BTW: Great tool,

jQuery(".terminal-wrap .terminal").attr("style","color:#00FF00");

Nov 8, 2014 - Authentication Agent

Fix “Could not open a connection to your authentication agent.” when using ssh-add {.blog-post-title}

If you’re trying to add identities to the authentication agent using ssh-add you may get this error:

Could not open a connection to your authentication agent.

The reason as the error message suggests is, ssh-add don’t know how to talk with the authentication agent.

The problem can be solved by setting SSH_AUTH_SOCK environment variable.

If you run ssh-agent you should get some output like this:

SSH_AUTH_SOCK=/tmp/ssh-agVZL13989/agent.13989; export SSH_AUTH_SOCK;
SSH_AGENT_PID=13990; export SSH_AGENT_PID;
echo Agent pid 13990;

now if you evaluate that command output in your shell, the variable will be set:

eval $(ssh-agent)

12 Useful “df” Commands to Check Disk Space in Linux

​1. Check File System Disk Space Usage

The “df” command displays the information of device name, total blocks, total disk space, used disk space, available disk space and mount points on a file system.

[root@tecmint ~]# df

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/cciss/c0d0p2     78361192  23185840  51130588  32% /
/dev/cciss/c0d0p5     24797380  22273432   1243972  95% /home
/dev/cciss/c0d0p3     29753588  25503792   2713984  91% /data
/dev/cciss/c0d0p1       295561     21531    258770   8% /boot
tmpfs                   257476         0    257476   0% /dev/shm

2. Display Information of all File System Disk Space Usage

The same as above, but it also displays information of dummy file systems along with all the file system disk usage and their memory utilization.

[root@tecmint ~]# df -a

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/cciss/c0d0p2     78361192  23186116  51130312  32% /
proc                         0         0         0   -  /proc
sysfs                        0         0         0   -  /sys
devpts                       0         0         0   -  /dev/pts
/dev/cciss/c0d0p5     24797380  22273432   1243972  95% /home
/dev/cciss/c0d0p3     29753588  25503792   2713984  91% /data
/dev/cciss/c0d0p1       295561     21531    258770   8% /boot
tmpfs                   257476         0    257476   0% /dev/shm
none                         0         0         0   -  /proc/sys/fs/binfmt_misc
sunrpc                       0         0         0   -  /var/lib/nfs/rpc_pipefs

3. Show Disk Space Usage in Human Readable Format

Have you noticed that above commands displays information in bytes, which is not readable yet all, because we are in a habit of reading the sizes in megabytes, gigabytes etc. as it makes very easy to understand and remember.

The df command provides an option to display sizes in Human Readable formats by using ‘-h’ (prints the results in human readable format (e.g., 1K 2M 3G)).

[root@tecmint ~]# df -h

Filesystem            Size  Used Avail Use% Mounted on
/dev/cciss/c0d0p2      75G   23G   49G  32% /
/dev/cciss/c0d0p5      24G   22G  1.2G  95% /home
/dev/cciss/c0d0p3      29G   25G  2.6G  91% /data
/dev/cciss/c0d0p1     289M   22M  253M   8% /boot
tmpfs                 252M     0  252M   0% /dev/shm

4. Display Information of /home File System

To see the information of only device /home file system in human readable format use the following command.

[root@tecmint ~]# df -hT /home

Filesystem      Type    Size  Used Avail Use% Mounted on
/dev/cciss/c0d0p5   ext3     24G   22G  1.2G  95% /home

5. Display Information of File System in Bytes

To display all file system information and usage in 1024-byte blocks, use the option ‘-k‘ (e.g. –block-size=1K) as follows.

[root@tecmint ~]# df -k

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/cciss/c0d0p2     78361192  23187212  51129216  32% /
/dev/cciss/c0d0p5     24797380  22273432   1243972  95% /home
/dev/cciss/c0d0p3     29753588  25503792   2713984  91% /data
/dev/cciss/c0d0p1       295561     21531    258770   8% /boot
tmpfs                   257476         0    257476   0% /dev/shm

6. Display Information of File System in MB

To display information of all file system usage in MB (Mega Byte) use the option as ‘-m‘.

[root@tecmint ~]# df -m

Filesystem           1M-blocks      Used Available Use% Mounted on
/dev/cciss/c0d0p2        76525     22644     49931  32% /
/dev/cciss/c0d0p5        24217     21752      1215  95% /home
/dev/cciss/c0d0p3        29057     24907      2651  91% /data
/dev/cciss/c0d0p1          289        22       253   8% /boot
tmpfs                      252         0       252   0% /dev/shm

7. Display Information of File System in GB

To display information of all file system statistics in GB (Gigabyte) use the option as ‘df -h‘.

[root@tecmint ~]# df -h

Filesystem            Size  Used Avail Use% Mounted on
/dev/cciss/c0d0p2      75G   23G   49G  32% /
/dev/cciss/c0d0p5      24G   22G  1.2G  95% /home
/dev/cciss/c0d0p3      29G   25G  2.6G  91% /data
/dev/cciss/c0d0p1     289M   22M  253M   8% /boot
tmpfs                 252M     0  252M   0% /dev/shm

8. Display File System Inodes

Using ‘-i‘ switch will display the information of number of used inodes and their percentage for the file system.

[root@tecmint ~]# df -i

Filesystem            Inodes   IUsed   IFree IUse% Mounted on
/dev/cciss/c0d0p2    20230848  133143 20097705    1% /
/dev/cciss/c0d0p5    6403712  798613 5605099   13% /home
/dev/cciss/c0d0p3    7685440 1388241 6297199   19% /data
/dev/cciss/c0d0p1      76304      40   76264    1% /boot
tmpfs                  64369       1   64368    1% /dev/shm

9. Display File System Type

If you notice all the above commands output, you will see there is no file system type mentioned in the results. To check the file system type of your system use the option ‘T‘. It will display file system type along with other information.

[root@tecmint ~]# df -T

Filesystem      Type   1K-blocks  Used      Available Use% Mounted on
/dev/cciss/c0d0p2   ext3    78361192  23188812  51127616  32%   /
/dev/cciss/c0d0p5   ext3    24797380  22273432  1243972   95%   /home
/dev/cciss/c0d0p3   ext3    29753588  25503792  2713984   91%   /data
/dev/cciss/c0d0p1   ext3    295561     21531    258770    8%    /boot
tmpfs           tmpfs   257476         0    257476    0%   /dev/shm

10. Include Certain File System Type

If you want to display certain file system type use the ‘-t‘ option. For example, the following command will only display ext3 file system.

[root@tecmint ~]# df -t ext3

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/cciss/c0d0p2     78361192  23190072  51126356  32% /
/dev/cciss/c0d0p5     24797380  22273432   1243972  95% /home
/dev/cciss/c0d0p3     29753588  25503792   2713984  91% /data
/dev/cciss/c0d0p1       295561     21531    258770   8% /boot

11. Exclude Certain File System Type

If you want to display file system type that doesn’t belongs to ext3 type use the option as ‘-x‘. For example, the following command will only display other file systems types other thanext3.

[root@tecmint ~]# df -x ext3

Filesystem           1K-blocks      Used Available Use% Mounted on
tmpfs                   257476         0    257476   0% /dev/shm

12. Display Information of df Command.

Using ‘–help‘ switch will display a list of available option that are used with df command.

[root@tecmint ~]# df --help

Usage: df [OPTION]... [FILE]...
Show information about the file system on which each FILE resides,
or all file systems by default.

Mandatory arguments to long options are mandatory for short options too.
  -a, --all             include dummy file systems
  -B, --block-size=SIZE use SIZE-byte blocks
  -h, --human-readable  print sizes in human readable format (e.g., 1K 234M 2G)
  -H, --si              likewise, but use powers of 1000 not 1024
  -i, --inodes          list inode information instead of block usage
  -k                    like --block-size=1K
  -l, --local           limit listing to local file systems
      --no-sync         do not invoke sync before getting usage info (default)
  -P, --portability     use the POSIX output format
      --sync            invoke sync before getting usage info
  -t, --type=TYPE       limit listing to file systems of type TYPE
  -T, --print-type      print file system type
  -x, --exclude-type=TYPE   limit listing to file systems not of type TYPE
  -v                    (ignored)
      --help     display this help and exit
      --version  output version information and exit

SIZE may be (or may be an integer optionally followed by) one of following:
kB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.

Aug 22, 2014 - Jekyll Clean Theme

Welcome to the sample post for the Jekyll Clean theme.

A simple and clean Jekyll theme using bootstrap (not to be confused with jekyll-bootstrap) that’s easy to modify and very modular in component and element reuse.

It uses Disqus for comments and includes Google Analytics support. Both of these features are disabled by default and can be enabled via _config.yml. You can also rip this code out of the templates if you like (footer.html and post.html). The beauty of Jekyll - keep things clean… Jekyll Clean!

The theme works well on mobile phones, using a collapsable nav bar and hiding the sidebar. The links pane in the sidebar is available on mobile through the nav menu, and you can do the same thing for any other sections added to the sidebar.

Don’t forget to occassionally merge against my upstream repository so you can get the latest changes. Pull requests are encouraged and accepted!

Installation

If you don’t have a blog already on github, start by cloning this repository. Best to do that directly on github and then clone that down to your computer.

If you already do have a blog, You can certainly apply this theme to your existing blog in place, but then you won’t be able to merge as the theme changes. If you re-apply your blog history on top of this theme’s gh-pages branch, it’s then easy to update to the latest version of the theme. You also don’t want to have to deal with resolving old conflicts from your existing history, so you may wish to to push your existing master off to a new branch so you have the old history and start a new branch with this as the start, merging in your _posts and other assets (after git rm’ing the current _posts.

Not ideal, but you have to make a choice - either apply it manually or base your blog off this theme’s branch. Either way it will work, and both have their own pros and cons.

You can setup an upstream tracking repository like so:

$ git remote add upstream git@github.com:scotte/jekyll-clean.git

And now when you wish to merge your own branch onto the latest version of the theme, simply do:

$ git fetch upstream
$ git merge upstream/gh-pages

Of course you will have to resolve conflicts for _config.yml, _includes/links-list.html, and _posts, and so on, but in practice this is pretty simple.

This is how I maintain my own blog which is based on this theme. The old history is sitting in an old-master branch that I can refer to when I need to.
