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.

15 (More) Awesome <a class="zem_slink" title="Conky (software)" rel="homepage" href="http://conky.sourceforge.net/">Conky Configurations You may have already seen our list of awesome Conky scripts or configurations, and perhaps applied or used some of them on your own <a class="zem_slink" title="Linux" rel="homepage" href="http://www.kernel.org/">Linux desktop. Since that collection was quiet popular, I decided to scour the web once again to gather more Conky scripts that I could share with all of you.

My comment : fc is the fix command of the bash builtin.
This is similar to using `!!` or

tee to a file descriptor

tee to a file descriptor

1

$ tee >(cat – >&2)

the tee command does fine with file names, but not so much with file descriptors, such as &2. This uses process redirection to tee to the specified descriptor.

In the sample output, it’s being used to tee to stderr, which is connected with the terminal, and to wc -l, which is also outputting to the terminal. The result is the output of bash –version followed by the linecount

when you press f9 'paste' is on , press f9 again and 'paste' is off, and so forth (works in insert-mode and command-mode)
