Programming :: Changing Color Of Output From Bash Script?
Apr 22, 2010I am writing a bash script that utilizes the output of another script (which I will refer to as script#2.) Script#2 is not owned by me, I cannot modify it. All of the output from script#2 is blue, which makes it difficult for me to read.
I would like to have the output of it changed to grey. Is there a way I can do that in my script? A command I can pipe the output to?
Edit: One other question related to this. I put a trap function in my script that works well. Script#2 essentially runs a tail -f. When I ctrl+c to stop it, it stops script#2 and never calls the trap in my script. Is there any way I can work around that?
Ubuntu :: Change The Color Of The Text Before The Input At The Terminal?
Jan 17, 2011I really don't know what to call it, but I want to change the color of text that appears before you type in whatever your input is.
For example:
Code:
negrabee@david-desktop:~$ ls /home/david/
I would want "negrabee@david-desktop:~$" to be in a different color. When you have whole bunch of commands and text in a full screen terminal, it gets really annoying to have to look for where you're entering the command so changing the color.
General :: [bash] Output Of One Script Is Input Of Another?
Mar 20, 2010Now, I have one script called "defcon" defcon gets the current DEFCON level and outputs it using echo.
Code:
#!/bin/bash
DEFCON=`curl -s http://members.tripod.com/~Swat_25/defcon.html | sed -n '/^$/!{s/<[^>]*>//g;p;}' | sed '/^$/d' | grep '[12345]$'`
echo "The current DEFCON level is $DEFCON"
The second script ("tweet") updates my twitter account.
Code:
#!/bin/bash
curl -s -u USER:PASS -d status="$@" http://twitter.com/statuses/update.xml > /dev/null
What I want to do is be able to update my twitter account with the current defcon status (this is really more of a learning thing than something I actually want to be doing). The original script for tweet replaced $@ with $1, but if I use:
tweet `defcon`
it only uses the first word in the string, similarly if I used $2 or $3.So I changed it to $@. The normal function still works, but typing:
tweet `defcon`
updates twitter with nothing.
EDIT I should mention the /dev/null is there to catch the output of curl, otherwise it won't run silently. It still updates twitter normally with the send to /dev/null

Programming :: Bash: Passing Output To Another Programs Input?
Nov 12, 2009I am not sure if that Subject really explains it, basically I have a script that executes a CLI java-applet that requires a passphrase from the user. I can easily execute this by issuing the -p argument followed by the passphrase however that shows up on possible logs or at least on the results of the ' ps ' command. If you do not supply this -p argument it provides a new line with the echo " Enter Passphrase: " and asks for input.
how can I provide a result/input for the Passphrase request and is it still possible to throw this application in the background with the ' & ' following the command? I have seen a few examples that show a /bin/expect that expects a result and sends a command however I would like to refrain from any extra dependencies. Example of Regular Execution of application:
Code:
$ /usr/local/***/**** -u USERNAME -r Default-Realm -f certificate.der

Ubuntu :: Bash Input - Output Error - Entire Computer Came Screeching To A Halt
Jul 21, 2010I am having a strange problem I've never encountered before. I have an Asus Eee S101 10.1" netbook with the 32GB SSD. I installed Ubuntu 10.04 Netbook Edition.
The other day, I was browsing with Firefox, when suddenly the entire computer came screeching to a halt. Had to power it down with the power button. After this happened, I have been unable to use the same Firefox profile I had been using. I had to start Firefox from the command line with the -ProfileManager switch, then create a new profile to keep browsing.
I wanted to completely get rid of the old profile, so from the Profile Manager I tried to delete the old one. Computer hung, had to reboot with the power switch. I then tried to browse to the .mozilla/firefox directory and delete the profile's directory there, from both Nautilus and the command line. Both times, the computer froze.
I tried a few more times, and the couple of times the computer didn't freeze, I got an error from the command line saying a Bash input/output error. After this error appeared, it would appear no matter what command I ran - I couldn't even run a sudo reboot now.
I can create/delete other files and directories, just not that Firefox profile.
Debian Configuration :: Change Prompt Color In Bash Shell?
Jan 13, 2010I am getting more and more comfortable working with the shell, thus I would like to change its prompt color to my liking, as it will be easier for me to distinguish commands vs. outputs.
I've read a couple of instructions of how to change the .bashrc file and am familiar with what the codes in PS1 mean. Except, this file can be intimidating to newbie eyes.
Where exactly on the file is it that I need to make the change?
Here is what I am trying to do. I would like my prompt to like exactly like the prompt I use in Backtrack - which consist in two different colors, one for the host and another for the pwd. Here is what the Backtrack .bashrc file looks like:
# /etc/profile: This file contains system-wide defaults used by
# all Bourne (and related) shells.
# Set the values for some environment variables:
export MINICOM="-c on"
export MANPATH=/usr/local/man:/usr/man:/usr/X11R6/man:/usr/local/share/man:/usr/bin/man:/usr/share/man
export HOSTNAME="`cat /etc/HOSTNAME`"
[Code]....
I also read that in order to have the same results when I log in as root, I will have to copy the modified .bashrc file into /root

Fedora :: Input / Output Error On NTFS HDD
Mar 25, 2011My dad is out of town for a while, so I've been using his computer to rip my DVDs with Handbrake. He has Windows Vista installed, so I did a full installation of Fedora 13 on a thumb drive and just run everything off of that. However, when I went to delete some of the encoded videos after I had moved them to my computer, I got a system error that said 'can't delete files: I/O error.' Now, if I try to boot up Windows, his computer is stuck on a black screen checking a bunch of dlls. He'll be back in a couple of weeks, so I'd like to have it fixed by then.

Apr 27, 2010I'm trying to clone 2 raid sets using dd.( have done this successfully many times in the past)
this time however running into issues.
dd stops with a 'input/output error'
dmesg shows:
A little above this i find
Background: this is a proliant sevrer & has got XFS filesystem on it. Last weeek it showed some XFS errors, tried to do a repair but didnt work.So thought would clone the raid set from a good 'source' server. ( we need this for a test purpose )
Before cloning I deleted raid & created again. everything looked OK, all disks showed as GOOD, but then the dd copy failed with above msg. I'm sure the source raid set is in good condition. Any thoughts on what could be wrong here & how I may be able to recover it?

Fedora Hardware :: Tape Input - Output Error ?
May 3, 2011I'm either missing the obvious or have four identically defective tape drives. Each is a Seagate or IBM Travan drive (yes, I know they're old and I need to access the data; they were in Win boxes) using QIC-80/DC-2120 media. I've been trying to solve this using three Fedora boxes (different versions) and one Debian machine.
The OS's recognize the drives and they show up as /dev/st0.
With no media in the drives, I get a status report; with media inserted, I get the same input/output errors.
Examples (all as root):
With tape inserted:
With no tape in drive:
With tape inserted
Everything I've found on Google suggests that the drives are defective.
Fedora :: Input/output Error When Copying Files To Fedora Live CD?
Dec 21, 2010I booted my Fedora 13 live CD on my Dell server, and configured networking and SSHd. On my desktop I logged into the live cd and started copying over a big file (1.5 GB) (i.e. copying from the desktop computer to the server). After copying about half the fil, the download fails with an error message about the filesystem being read-only.I've seen this exact same behavior on both i386 and x86_64 of the same live CD, but don't know why it's happening. I've also had the same issue when copying small files. In /var/log/messages these messages are repeated many times:
Code:

Fedora :: On Boot: Mdadm Failed To Start Raid: Input/Output Error?
Jul 31, 2010I have a strange issue with my RAID5 array - it worked fine for a month, a couple days ago it didn't start on boot with mdadm reporting "Input/Output error" - I didn't panic restarted my computer, same error. Then opened a Disk utility and it reported State: Not running, partially assembled - don't know why, I've pressed Stop RAID Array and started it again, voila - it reported State: Running - I've checked components list and there was nothing wrong with it. So I run Check Array utility, waited almost 3 hours to finish it and it worked since than, till today's morning - I've started my computer, and here we go, same error.
See screenshots:
This is an initial state just after computer startup:
This is after I stop and start RAID5:
This is a components list:
I can see nothing wrong there yet not sure why mdadm fails on boot. I do not really like the windows solution I guess, when I check my array again, it will work fine again, but it then can fail in the same way without known reason.

View 2 Replies View RelatedUbuntu Multimedia :: Change Stereo Mic Input To Mono Input?
Nov 4, 2010I recently got a real fancy unidirectional microphone, but when I go and use it, something strange happens. The mic is a mono mic, but when I record something, it appears to think it's stereo. Instead of having the same thing on both channels, it puts it all in the left channel, and silence on the right channel.
I tried fiddling with alsamixer. In capture (F4), adjusting the "Capture" device has an effect. However, it doesn't do anything useful. Lowering the right channel to zero does nothing, lowering the left channel to zero creates silence, and disabling the right channel creates silence.
In my System>Preferences>Sound (or pavucontrol, or what-have-you), there are "Analog Stereo Input" and "Analog Stereo Duplex" options there, but no "Analog Mono Input" or "Analog Stereo Output + Analog Mono Input" options (the latter being ideal).
Something interesting, though, if I do this:
Code:
arecord -r 96000 -D pulse -c 1 -vv -V mono /dev/null
it works correctly and outputs on both channels. But if I do
Code:
arecord -r 96000 -D pulse -c 2 -vv -V stereo /dev/null
then it's back to the same behavior. The VU meter on the second command shows the left channel going up and down as I make noise, but the right one always at zero.
The machine does have a crap internal mic built in to the screen bezel. If I do either of the above commands, they both work correctly. The stereo VU shows the same activity for both channels.
The machine is a Eee 1015PED, which has Intel integrated sound. Something probably insignificant is that the mic has a 1/4 inch mono plug, and to get it to plug into the Eee, I needed to get a 1/4 female to 1/8 male adapter. The mic's 1/4 plug is mono (duh) and therefore two-conductor, but the adapter I got is stereo, or three conductor (L, R, GND). I don't know if this is tripping something in hardware to tell it it's stereo or something.
I tried the mic on my desktop, which has a SB Audigy 4 (the non-pro flavor) and that has the "Analog Mono Input" function, so that works fine. Is there some way to turn this stereo input into mono input?
