From the other machine open a web navigator and go to ip from the machine who launch netcat, http://ip-address/

If you have some web server listening at 80 port then you would need stop them or select another port before launch net cat ;-)

* You need netcat tool installed

You must get your Backup Url from: http://ROUTER_DYN_DNS/admin-bwm.asp under "Backup".

I set it up in a curl

or, to process a single directory:

or, for a single directory:

When expanding, bash output the command, so don't be affraid if you type the command.

Here is the details:

First examples:

First argument:

echo barfoo

barfoo

(Note that typing echo foo bar foobar barfoo && echo !$, bash substitute !$ with $:1)

Last argument:

echo foo bar foobar barfoo && echo barfoo

foo bar foobar barfoo

barfoo

All the arguments:

echo foo bar foobar barfoo

foo bar foobar barfoo

The third argument:

echo foo bar foobar barfoo && echo foobar

foo bar foobar barfoo

foobar

You may want to add {} for large numbers: echo !:{11} for example

Now with path:

/usr/bin/foobar

For the head:

echo /usr/bin

/usr/bin

And the tail:

echo foobar

foobar

You also may want to try !:h and !:t or !!3-4 for the third and the fourth (so !!:* == !!:1-$)

tar options may change ;)

c to compress into a tar file, z for gzip (j for bzip) man tar

-print0 and -0t are usefull for names with spaces, \, etc.

seq allows you to format the output thanks to the -f option. This is very useful if you want to rename your files to the same format in order to be able to easily sort for example:

And

foo1

foo10

foo4

foo7

But:

So

foo01

foo04

foo07

foo10

this will find text in the directory you specify and give you line where it appears.

/proc/cpuinfo contains information about the CPU.

Search for "processor" in the /proc/cpuinfo file

wc -l, counts the number of lines.

grep -sq "" filename && command

grep can be used in combination with && to run a command if a file exists.

This commands lets you generate a random number between the range [$START; $END].

The trick here is to use the brackets [ ] around any one of the characters of the grep string. This uses the fact that [?] is a character class of one letter and will be removed when parsed by the shell. This is useful when you want to parse the output of grep or use the return value in an if-statement without having its own process causing it to erroneously return TRUE.
