BASH - Simple random password generator

Posted 1 year, 5 months ago at 8:20 pm. 2 comments

Ever wondered how cool it will be to have an random password generator in your shell?

Here’s a little bash script i wrote:

Put this

#!/usr/local/bin/bash
if [ -n $1 ]; then
      CHARS=$1
      while [[ "$COUNT" -ne "$CHARS" ]]; do
            let COUNT=COUNT+1;
      done
else
      COUNT=8; # DEFAULT NUMBER OF CHARACTERS
fi

/usr/bin/perl -le'print map+(A..Z,a..z,0..9)[rand 62],1..'$COUNT;

into /usr/local/bin/passgen and then chmod it properly:

[root@box ~]# chmod +x /usr/local/bin/passgen

Now try it in action:

[root@box ~]# passgen
UJXG1JMx
[root@box ~]# passgen 15
l3LMgNOuCK3OYnH
[root@box ~]# passgen 1 
J
[root@box ~]#

Have fun! :-P
