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.

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.
