[CLUE-Tech] RE: removing spaces from filenames?

This one was tricky, imho. I used find's depth command to work in
reverse order, since once one changes a directory name the previous
output of find will no longer point to a real file. I piped find's
output into the perl script.
Here's some sample output:
$ find . -depth -print | perl /path/to/this_perl_script.plx
mv "./o d/a pp ong.set" "./o d/a_pp_ong.set"
mv "./o d" "./o_d"
mv "./te p" "./te_p"
And, here's the perl script:
#!/usr/bin/perl
use strict;
while ( <> ) {
chomp;
if ( / / ) {
my @path = split( /\//, $_ );
my $base = pop( @path );
my $path = join( "/", @path );
my $old = $base;
( my $new = $old ) =~ s/ /_/g;
if ( $new ne $old ) {
print( qq|mv "$path/$old" "$path/$new"| );
print "\n";
system( qq|mv "$path/$old" "$path/$new"| );
}
}
}
Thank you,

Subject: [CLUE-Tech] removing spaces from filenames?
Reply-To: clue-tech at clue.denver.co.us
Hi,
I have a _bunch_ of files that were created on a windoze system with
embedded spaces in their names. Can anyone recommend a technique to
programmatically rename the files - replacing ' ' with '_' on both the
file and dir names?
I am thinking perl, but I am not sure what sysntax I would need to use
to search and rename.
TIA
aloha,
dave

Did you search the clue.denver.co.us mail archives? Jed posted
something doing that...I'm pretty sure. I don't recall if it was
clue-tech or clue-talk.
Maybe he will chime in ;-)

Subject: [CLUE-Tech] WEP security?
Reply-To: clue-tech at clue.denver.co.us
I was trying to enable WEP on my laptop to discourage wardrivers or
neighbors from trying to hijack my wireless network, but the
wicontrol(8)
man page says this...wicontrol is what is used on FreeBSD, BTW, to set
up
wireless configuration.
I knew WEP was on shaky ground, but this makes it sound like cracking
WEP is
trivial. Has anyone been cracked at work or at home, and if so, how did
you
find out about it?
======
BUGS
The WEP encryption method has been broken so that third parties can
recover the keys in use relatively quickly at distances that are
surpris-
ing to most people. Do not rely on WEP for anything but the most basic,
remedial security. IPSEC will give you a higher level of security and
should be used whenever possible. Do not trust access points or
wireless
machines that connect through them as they can provide no assurance that
the
traffic is legitimate. MAC addresses can easily be forged and should
therefore not be used as the only access control.
The attack on WEP is a passive attack, requiring only the ability to
sniff packets on the network. The passive attack can be launched at a
distance larger, up to many miles, than one might otherwise expect given
a
specialized antenna used in point to point applications. The attacker
can
recover the keys from a 128-bit WEP network with only 5,000,000 to
6,000,000
packets. While this may sound like a large number of packets, emperical
evidence suggests that this amount of traffic is generated in a few
hours on
a partially loaded network. Once a key has been compro- mised, the only
remedial action is to discontinue it and use a new key.
See http://www.cs.rice.edu/~astubble/wep/wep_attack.html for details of
the attack.
If you must use WEP, you are strongly encouraged to pick keys whose
bytes
are random and not confined to ASCII characters.

I have no experience with WEP, definately none WRT cracking it ;-)
But, I have read in numerous places that it is in no way secure. I=20
would use IPSEC, as recommended in the notes above.

I get 'extra spaces' and 'function gensub never defined' errors
Ideas?

Oops, extra paren inside the argument list.

Whare is gensub() defined?
[davep at dp:~]$ cat bin/aren
#!/bin/bash
ls | awk '{print "mv " $1, gensub(" ","_",1,$1)}' | sh
[davep at dp:~]$ aren "Dir with Spaces"
awk: line 2: function gensub never defined

CLUEbies,
I have been playing with phpweblog, and like it, but I really wish it
could do a more nested/threaded layout. i.e. Ability to define top-level
folders and then subjects withing those.
Does anyone know of a blog that has this built-in? Would prefer
php/mysql- based.
aloha,
dave
