Decided to create a gtkdialog front-end, which incorporates the above ideas in addition to making sure the end result has numbers, symbols, and letters. Generates to editable entry box

front end:

Code:

 
#!/bin/sh

## Front end for password-generator.sh. jpeps 12/11


touch /tmp/pass
export GEN="/usr/local/passgen/password-generate.sh"

Generate() {

"$GEN" >/tmp/pass



## check for symbols & numbers
 
while ([ ! "$var" ]); do

 # check for numbers
 var="$(cat /tmp/pass | grep "[0-9]")"
 ## check for sympbols
 [ "$var" ] &&  var="$(cat /tmp/pass | sed 's/[0-9a-Z]//g')"   

 ## if no sybols and numbers, re-generate
 [ "$var" ] || "$GEN" >/tmp/pass
done
}
export -f Generate


export MAIN_DIALOG='
<window title="Random Password" default-width="210">
  <vbox>
    <entry>
       <variable>ENTRY</variable>
       <input file>/tmp/pass</input>
    </entry>
    <hbox>
      <button tooltip-text="Generate new password" space-expand="true">
         <input file icon="gexec"></input>
         <label>" Generate "</label>
         <action>Generate</action>
         <action>refresh:ENTRY</action>
      </button>
   
      <button cancel></button>
    </hbox>
  </vbox>
</window>

Seems to work better:
Code:

tr -cd '0-z' </dev/urandom |head -c ${PASSWORDLENGTH:-10}


For some reason, this tended to hang up from within a program, requiring me to kill the process.
