XX is your device partition number like /dev/sdc1 .
to see how many inodes your partition have type:
$ df --inodes (or df -i)
Default formatting with ext4 would create small inode count for the new partition
if you need big count of inodes is the fstype news the correct one.
in debian you can see which fstype exists as template in:
$ vim /etc/mke2fs.conf
if you format default ext for a partition size with 1TB you would get 1 Million inodes (not enough for backupStorages)
but if you format with fstype news you would get hunderd of millions of inodes for the partition.
you have tune
$/etc/sysctl.conf
also with following sysconfig parameters
$ fs.file-max = XXX
$ fs.nr_open = XXX
where XXX is the count of max inodes for whole system
Works for most distributions, tested on Ubuntu, Fedora, CentOS, Gentoo, SUSE, RedHat.
Debian and Slackware:
$cat /etc/*version
Generates the list of clients (IPs addresses) that have used the Squid webproxy according to the most recent log. Every IP appears only once in the list.
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
Lots of fun to run on nfs clients when the server or network connection is having issues
Create transparent image to use as icon, watermark for other images, etc.
Randomly decide whether to run a command, or fail.
It's useful for testing purposes.

Usage: ran PERCENTAGE COMMAND [ARGS]
Note: In this version the percentage is required.

This is like @sesom42 and @snipertyler's commands but in a USABLE form.
.
e.g. In your complicated shell script, put "ran 99" before a crucial component.
Now, it will fail 1% of the time allowing you to test the failure code-path.
$ ran 99 my_complex_program arg1 arg2
These are my favourite switches on pwgen:
-B Don't include ambiguous characters in the password
-n Include at least one number in the password
-y Include at least one special symbol in the password
-c Include at least one capital letter in the password
It just works!
Add a number to set password length, add another to set how many password to output. Example:
pwgen -Bnyc 12 20
this will output 20 password of 12 chars length.
Shows a simple clock in the console
-t param removes the watch header
