&& The Notes Folder



This folder contains quick notes written about various subjects
    
...

  * getting a page via an authenticating proxy server
  >> curl -x proxy.utas.edu.au:8080 -U bobj http://www.server.net 

* getting a page via an authenticating proxy server as user 'bobj' with password 'asecret'
  >> curl -x proxy.utas.edu.au:8080 -U bobj:asecret http://www.server.net

  Supplying the password in this manner is possibly not a good idea from a security
point of view 

  
  * a function which prints its own name
  >> test () { echo "$FUNCNAME"; }
  
  * a function which prints its own name
  >> test () { [ -z "$1" ] && echo "$FUNCNAME: parameter needed" && return 1; }
  
  * download a text file through a proxy and edit it with vim
  ------------------------------
  function edn {
    curl -x proxy.utas.edu.au:8080 -U bishop:secret http://bumble.sourceforge.net/notes/index.txt -o ~/notes.txt
    vim ~/notes.txt
  }

 * upload some file to a webserver cgi script which has http authententication through a proxy
 function up {
  [ -z "$1" ] && echo 'no parameter' && return 1;
  curl -F name='../htdocs/notes/'$1 -F contents='<'$1 -u user:upass -x proxy.utas.edu.au:8080 -U bob:proxypass http://www.server.net-bin/save.cgi
}

 * upload data from the file 'list.txt' to a webserver
 >> curl -F comment=<~/docs/list.txt www.server.net/cgi-bin/save-comment.pl
The curl line above is equivalent to the user filling out a web form and posting it.
The form would look like
   
 >> <form action='cgi-bin/save.pl'><textarea name=comment></textarea></form> 

* upload the file 'notes.txt' with curl through a proxy server to a server cgi script
>> curl -F filename='../htdocs/notes/index.txt' -F filecontents='<notes.txt' -u mjb:httppass -x proxy.utas.edu.au:8080 -U bishop:proxypass  http://bumble.sourceforge.net/cgi-bin/save.x.cgi



UTAS STUFF
   
  I have being trying to get curl to work

* trying to upload a file 'notes.txt' with curl through the proxy server
>> curl -F filename='../htdocs/notes/index.txt' -F filecontents='<notes.txt' -u mjb:httppass -x proxy.utas.edu.au:8080 -U bishop:proxypass  http://bumble.sourceforge.net/cgi-bin/save.x.cgi

  
  * a simple bashrc file for utas to allow me to edit stuff
  -----------------
# I like this for big edits
set -o vi

# I wonder if this is persistent on the server
alias al='vim ~/.bashrc; source ~/.bashrc'

alias sn="curl -F filename='../htdocs/notes/index.txt' -F filecontents='<notes.txt' -u matth3wbishop -x proxy.utas.edu.au:8080 -U mjbishop: http://bumble.sourceforge.net/cgi-bin/save.x.cgi"

function edn {
  curl -x proxy.utas.edu.au:8080 -U mjbishop: http://bumble.sourceforge.net/notes/index.txt -o ~/notes.txt
  vim ~/notes.txt
}

OLD NOTES

* play a random wav file in the current folder
>> mjbishop$ f=$(ls *.wav | head -$[$RANDOM%$(ls | wc -l)] | tail -1); afplay "$f"

* slightly shorter way to do the same
>> mjbishop$ f=$(ls *.wav | sed -n "$[$RANDOM%$(ls | wc -l)]p" ); afplay "$f"

* an even shorter way to do the same thing but wont work if some filenames have spaces
>> a=($(ls)); afplay "${a[$RANDOM%${#a}]}" 

* display the fifth file in the current folder
>> a=($(ls)); echo ${a[5]}

* display a random file in the current folder
>> a=($(ls)); echo ${a[$RANDOM%${#a}]}

* an interpreting loop which breaks when the user enters 'q'
>> while true; do read a; echo $a; [ "$a" = "q" ] && break; done
