Bash Script - Random Generator

[spbr]

Hi,

Currently, I've got the following

to produce a random 13 character string, which includes all printable ASCII characters.

#!/bin/bash
LIST="a A b B c C d D e E f F g G h H i I j J k K l L m M n N o O p P q Q r R s S t T u U v V w W x X y Y z Z 0 1 2 3 4 5 6 7 8 9 ! £ $ % ^ & ( ) , . / ; ' # [ ] { } : @ ~ < > \ ? * + - = \"  _ |"
RAMPWD=$(cat /dev/urandom | tr -dc "$LIST" | fold -w 13 | head -n 1)
echo "$RAMPWD"

The problem is that sometimes the output results into this:

f~VfrI▒ocgU6[

which is useless for a WEP password and just doesn't work

Is there any other random generator for bash that I could use and still include all printable ASCII characters.

Thank you

could it be you have " inside the list=" *chars here* "

Thank you,

 

The trouble is I've used the same list in creating permutations and it works fine.

So I'm pretty sure its got something to do with the random generator part. 

 

Thank you

pwgen () {
list=$(cat /dev/urandom |head |openssl  base64 | tr -d \+ |tr -d \/ | cut -c1)
echo $list | tr -d " " | cut -c5-16
