cli add

I have not updated – forget the GUI in a very long time, and I did have some nice tricks and tips there, so I decided to bring it over here.

It is all tagged with cli for easy searching, plus I added a whole mess of other tags.


dd(8) with progress

I needed to write an iso image to a USB key, and the typical way is
with just dd(8), but I wanted a progress bar. A quick google later,
and I get:

pv -tpreb isoname | sudo dd of=/dev/sdd bs=1024

Which will write the iso image to the USB stick sdd, and give me a
progress bar, tell me how fast it is writing, and give me an eta when
finished. Perfect.

An Update to ‘Window Managers?’

Way back, I wrote a quick blurb on Window Managers for running under X.

Well, a while back I switched to Ubuntu for my OS of choice. As you may know, the fine folks at Ubuntu switched to default window manager to something called Unity, which caused a stir. I tried it for a while, but decided that it was too heavy, and too mouse-centric.

So, what to do? Well, I went back to my old standby wmfs, Window Manager From Scratch. This is a modern WM with systray support, full Ximirama and Xrandr support, tiles, and is mainly driven from the keyboard. Life is good.

To install (same steps as for Fedora, RHEL, or Ubuntu), download the source, and install the needed development libraries for: X11, Xft, freetype, Xinerama, Xrandr, and Imlib2. I used the native packages from the OS. Then, simple do a

sudo make install

(you do build software as a normal user, right?)

This will install all the needed bits and configs into the correct place. Under Ubuntu 11.10, there was an entry from the login screen to let me chose wmfs.

Config is handled in $HOME/.config/wmfs/wmfsrc which you can copy from /etc/xdg/wmfs/wmfsrc.

EDIT 2016-11-30: It seems the domain is no longer active.
The wmfs website has very nice documentation as well as likes to some people’s configs with screen shots.

It runs very fast, and very lean:

 Private + Shared = RAM used Program 3.9 MiB + 310.0 KiB = 4.2 MiB wmfs

Check it out, I am sure you will like what you see.

Search your email!

Search your email!

One of the features that most of the pretty GUI mailers offer you is the ability to search your email. While this is not a feature I use regularly, it is one which when you need it, you really need it. I have used grepmail in the past, but it slow for me (it scans the mail files every time) and the big thing for me is that is only supports mbox files, and I use maildir since I use offlineimap.

I recently found mairix. While I have not been using it long, so far I am very impressed with it. It uses an index to speed up the search process, and it smartly adds only new or changed files to the index. The first indexing run was only a few seconds on my archive of almost 15,000 mail messages. I have it scheduled to update the index every 15 minutes, and I never notice the load this will put on the system.

To integrated mairix with mutt, I wrote a quick little script to search from within (or without) mutt:

# USAGE: ./
# DESCRIPTION: search mail stuff

rm -rf $HOME/Maildir/mfolder
echo " t::word Match word in the To: header.
 c::word Match word in the Cc: header.
 f::word Match word in the From: header.
 s::word Match word in the Subject: header.
 m::word Match word in the Message-ID: header.
 b::word Match word in the message body.
 d::[start-datespec]--[end-datespec] Match messages with Date: headers lying in the specific range.
 z::[low-size]--[high-size] Match messages whose size lies in the specified range.
 n::word Match word occurring as the name of an attachment in the message. Since attachment names are usually long, this option F::flags Match messages with particular flag settings. s meaning seen, r meaning replied f meaning flags prefixed by a - to negate its sense. The a:: search pattern is an abbreviation for tcf: Match words The word argument to the search strings can take various forms.
 ~word Match messages not containing the word. 
  word1,word2 This matches if both the words are matched in the specified message part.
  word1/word2 This matches if either of the words are matched in the specified message part.
 substring= Match any word containing substring as a substring
 substring=N Match any word containing substring, allowing up to N errors in the match.
   For example, if N is 1, a single error is allowed, where an error can be * a missing letter * an extra letter * a different letter.
 ^substring= Match any word containing substring as a substring, with the requirement that substring occurs at the beginning of the matched word.
 d::start-end Specify both start and end explicitly "
echo -n "Enter your search string: "
read string
mairix $string
mutt -f=mfolder
rm -rf $HOME/Maildir/mfolder

Then, I bound this to “S’’ from within mutt:

 macro index,pager S "!mailsearch\n" 

This will give me a reminder of the search command, run the search, and then give me the search results in a new mutt session.

wifiroamd, Intel PRO/Wireless 3945ABG, and Fedora

wifiroamd, Intel PRO/Wireless 3945ABG, and Fedora

One of the things that has annoyed me about Fedora has been the decision to switch over to using NetworkManager to manage all network connections.

Now, on the service this has a lot of advantages. A lot of work has gone into it, and it just works for a vast majority of the installations out there. They have made it so the move from wired to wireless and back can be done without the user doing anything. They have also seamlessly tied in Dial-Up Networking if you still need a modem or use a wireless modem. They even have two-click access to your VPN which is pretty cool.

All these are things which are very good for Linux users. The biggest drawback to all this? The need for a user-space program to manage the non-hardwired connections. Which means that in order to be able to have any network running besides the good old twisted-pair copper, you have to have a little applet running as you, and it has to have a systray somewhere to display. Which means you have to be a) logged into the system and b) you have to be running a window manager which supports having a system tray. Now, Fedora gives you lots of choices for the second part now days. You have Gnome, KDE, XFCE, and LXDE. All are perfectly usable window managers. But, they still require you to be logged in to X. And, I do not use any of them.

So, what is a cli-loving Fedora user to do? Well, there is this great program called wifiroamd. It will handle the same basic tasks that NetworkManager handles. It will automatically configure your wifi interface and connect to the wifi networks or the locate hardwired NIC if it cannot. You can configure it to run scripts per connection, so for example, you can change your firewall rules for different networks (shields down at home or the office, but up full at the coffee house), or you could bring up your VPN connection when you start using a given wireless network.

One tip I picked up from the author was that if you have multiple AP’s in range, an you want to select once AP over the other, is under the /etc/wifiroamd/connections directory, simply link the AP info you do not want to the one you want:

ln essid:my_home_ap essid:bad_ap

where essid:my_home_ap is your AP with the keys and other information you want, and essid:bad_ap is the one you do not want to connect to. My neighbors have some very powerful AP’s which have a habit of showing up high than mine, but I have no problem with them now.

I have been using this set up under Fedora since FC6 days, but when I upgraded to F10, this stopped working. wifiroamd would try to scan for an AP, and not find anything. The change, it turns out, is that when I switched from using the iw3945 driver to the native iwl3945, wifiroamd could no longer see the wireless NIC due to the wpa_supplicant process, but NetworkManager could. Simply stopping and disabling wp_supplicant and NetworkManager, and wifiroamd started working again! I am a happy camper again.

C*MUS – A music manager for the terminal

C*MUS – A music manager for the terminal

C*mus is an advanced music juke-box for *inx and Window operating systems. It can handle the modern audio file formats: FLAC, Ogg/Vorbis, MP3 , Wav, AAC , MP4, .mod, .s3m, .mpc, mpp, .mp+, .wma, and .wv . It also can deal with many different types of audio output systems: ALSA, libao, ARTS, OSS, Sun, and WaveOut on Windows. The typical features of an electronic juke-box are supported like play lists and random/shuffle play, in addition to easily switching between playing from the library, an artist, or a single album with a simple keystroke.

C*Mus is pretty painless to install from source. The website lists the build dependencies with links.


One of the features I really enjoy and use is the en-queue function. I tend to use this two ways. The first is when I am listening to a song, and want to listen to similar songs, I go find them in my library, and I queue them up with a simple keystroke. A dynamic play-list, if you will. Then, I can simply create a more permanent playlist from this temporary list.

The second way is using the helper program cmus-remote to be able to queue up tracks from a different terminal, or from a script. My podcatcher program (bashpodder) will queue up the podcasts it just downloaded for me, so I can listen to them first thing in the morning.

Keystroke and CLI

CMus is developed to be driven via keystrokes. The default mapping is set up to be comfortable for those use are familiar with VI but, it is very easy to remap the keys to make it more comfortable. CMus will automatically save the current settings on a clean exit. The default mappings for selecting and updating views, moving through songs forward and backwards in small and large increments, adding to play list and queue lists.


One of the very powerful features is simple filters. You can set a filter for your 80’s Metal Bands or your Classical music. Many of the common tags can be used for filter on. Things like filename, artist, album, title, genre, discnumber, tracknumber, date (year), duration (seconds), and tag.

Google’s Calendar on the Command Line!

Google’s Calendar on the Command Line!

You love your comfortable command line, but all the cool kids are playing in the Web 2.0 web space, and you want to stay true to your roots?  Want a Web 2.0 calendar, but still love (or need) command line access?

I just found the answer: gcalcli. This little tool will let you list your appointments, get an list your events, get an agenda, print ascii rendering of your calendar for the week or month.  You can even add events to the calendar.

I like the fact that I can easly get at my gcalendar from anywhere (even my cell phone), and now I can do it from my shell.

The only downsides so far?  The code has not been updated since October of 2007, and the speed can be a little slow sometimes. I am going to play with it for a while to see if I like it enough to replace remind.

Alerting with Remind

Alerting with Remind

Back in my article on Remind, I talked about the simple power of remind to power your scheduling needs.  That is all fine and good, but how to you get it to tell you when you have an event?

In its simplest form, when you run _remind _ from the command line, it will not only display the current day’s reminders, but it will run in the background and wake up to tell you about other reminders on the screen while you work.

This is fine, but what happens if you do not have that termial open in front of you?  Well, I have two ways I approach that issue.

First, when I run under X (yeah, yeah, I know, but I use cli tools under X), I have this added to my .xinitrc:

remind -z -k’xmessage -buttons okay:0 -default okay %s&’ ~/.reminders &

Let’s look at the command line:

  • The -z tells remind to wake up every 5 minutes and reread the .reminders file.
  • The -k tells remind to run a command instead of simply printing the reminder to the screen
  • xmessage -buttons okay:0 -default okay %s& is the secret sauce of this.  This is the command run when there is an alarm.  This command line calls xmessage (which is on pretty much any box with X) to display the alert.  You could use zenity or kmessage, or winpopup, or whatever.  This is what puts the alert in your face when you are not looking at the screen.  The & is needed to make this command non-blocking by putting it in the background.

That all good if you are setting at your computer.  But, what do you do when gasp you leave to computer?  This is a little tricker.  For this, my solution needs two things: 1) a computer which is always on and 2) a way to send messages to your cell phone/pager (sms or email).  I have a cron job which checks to make sure remind is running, and restarts it if it is not (I use a hosting provider which does not like long running processes).  The command line is similar to the one for X, but with a difference:

TZ=CDT6CST ~/bin/remind -z -k”echo %s

Pizza Party – Command Line Pizza ordering program

Want a pizza, and do not want to fire up that pesky GUI?  We have the solution for you: Pizza Party – Command Line Pizza ordering program

Currently, only from Dominos, so if you do not have one near you who accepts on-line orders (sigh, mine does not), then you are out of luck.
