Re: aptitude or apt-get: how to use the jolly character?

Right, the shell performs "globbing", matching such patterns against
pathnames and providing multiple arguments to the underlying command. As
packages aren't accessible via pathnames, you can't count on your shell
finding them.
How to do then?
Aptitude itself uses regular expressions (I like PCRE, might just be posix-
extended) to match against package properties paired with "atoms" or
"operators" (I can't remember the correct terminology) to select which
property or combine searches.
In this case use the aptitude search string "~n^texlive" or simply
"^texlive" since "~n" is the default.
Since these aptitude search expressions can have characters in them that the
shell interprets (e.g. *, ?, and [] all have special meaning in both regular
expressions and shell "glob"s), you'll want to surround the expression in
single-quotes to prevent the shell from interpreting it -- passing it
directly to aptitude after removing the quotes.
Something like:
aptitude purge '^texlive'
Of course, things get really confusing when they have special meanings
in both the shell and regexps, and you want to negate both of them.
Suppose I want to grep for a letter (f in this example) followed by the
asterisk in a file, I'd need to use this command:
grep f\\\* $file
grep f* $file would search for the name of any file in the current
directory beginning with f, in that file (or the below if no files begin
with f)
grep f\* $file would search for 0 or more occurences of the letter f in
that file (in other words, every line)
grep f\\* $file would search for the name of any file in the current
directory beginning with f\ in that file (or the below if no files begin
with f\)
grep f\\\* $file would search for an f followed by an asterisk.
And that gets even more confusing when you put it in C, in, for example,
a system() call:
system("grep f\\* $file");
(The backslashes are doubled up so that C does not interpret them as its
own escape characters, like \n). And if you wanted (for example) a
newline in the middle of that command, you would probably die from
confusion :p

Why I see that it works different regarding the set environment (for some sh, for others bash), for, say, autorun scripts such as .profile, bash_profile, if sh links to bash? Thank You for Your time. On most modern systems, sh is pretty much the same as bash (although yours may have sh linked to dash, I'll come back to that later), but in a "compatible mode" (AFAIK just with things like the prompt changed so it looks more like sh, and it reads different startup scripts, and a few of the POSIX-breaking features are disabled). Sh is basically a general executable that is linked to the bourne-compatible shell of your choice (usually bash, but again, sometimes dash). Bash (Bourne Again SHell) is the actual executable sh links to on most systems, and has probably the most features of all the bourne shells. Dash (Debian Almquist SHell) can sometimes be set instead of bash: this is much faster, but has fewer features. Some poorly-designed shell scripts will fail with systems with sh linked to dash. Other systems (mainly embedded systems) have sh linked to busybox - this has even fewer features, but is used because it has every major tool in one executable. Bash in sh mode is no less secure than bash in bash mode. If yours is linked to dash or busybox, those are likely to be more secure due to the fewer features. But there isn't really much of a difference, so don't worry. As for your last question, see above. Sh-compatible bash loads different startup scripts to bash bash.
