  <td>
    <div class="text codecolorer">
      &nbsp;cp_p() { if [ `echo "$2" | grep ".*/$"` ]; then pv "$1" > "$2""$1"; else pv "$1" > "$2"/"$1"; fi; }

Print all environment variables, including hidden ones

Print all environment variables, including hidden ones

  <td>
    <div class="text codecolorer">
      for _a in {A..Z} {a..z};do _z=${!${_a}*};for _i in `eval echo "${_z}"`;do echo -e "$_i: ${!_i}";done;done|cat -Tsv
    </div>
  </td>
</tr>

This uses some tricks I found while reading the bash man page to enumerate and display all the current environment variables, including those not listed by the ‘env‘ command which according to the bash docs are more for internal use by BASH. The main trick is the way bash will list all environment variable names when performing expansion on ${!A*}. Then the eval builtin makes it work in a loop.

Skyline with Red color – from mobile.

Have you ever wondered, how the red skyline would look if you did not have your favourite camera with you to capture it. I had only my Samsung Omni Windows Mobile with me to capture this, do comment on how they look 🙂

Photo Editing with nice border and preparing for print.

Working with photos in Linux is very easy with lots of viewers/editors/managers and what not. Not that there are not many options in Windows but most of them are not free. BEST case scenario is that you might get a evaluation version (i.e. if you do not use pirated/cracked version) of software‘s. Me, being completely against pirated and cracked version or evaluation version (if not, planning to buy the same) like the freedom of choice with Linux.
