General :: Scripting - Feed An Input File Into An If Statement Line-by-line
Dec 23, 2009I am trying to write a script that takes an input file ($FileName) and an intermediate file ($FileName.info) and removes lines from $FileName if the value in $2 of $FileName.info is <75.
I can't figure out how to feed only one line of the .info file to the if statement at a time so that it will perceive it as an integer instead of a list.
The error I am getting now is ./script.sh: line 6: [: : integer expression expected
Sample input $FileName

Programming :: Awk - Input From One Line - Execute Program - Input From Next Line - Execute Program
Sep 25, 2010I have a file with two fields of numbers that I want to use as input for another program.
Code:
The above code does not work, as I think it would take the whole first and second fields as the input for one particular instance of the program 'inputbashangle'. What I want is to get the first two numbers from the first line of the file 'outfailtest', execute 'inputbashangle' with them, then move on to the first two numbers of the second line for all the lines of 'outfailtest'.

Programming :: Read Each Line Of A File As Input?
Jun 21, 2011I'm writing a program which now accepts user input:
Code:
echo "Enter a date in the format YYYY MM DD hh mm ss."
read gregyr gregmo gregdy greghr gregmn gregsc This lets the user input a date and time, such as 2011 06 21 15 12 45, and have each number assigned to their corresponding variable. Later in the program, these variables are put into an equation, and then the terminal spits out the answer. Now I have to have the program read all of the lines from a text file, which is in this format, assign the variables.

Ubuntu Multimedia :: Switch From Audio Input From Mic To Line On 9.10?
Feb 28, 2010I wanted to take an audio feed from a stereo amplifier into my HP Pavilion DV6 laptop, in order to digitally record some old vinyl.
In the Sound Preferences tab, I seemed to be able to record easily from the internal mic, but there seemed to be no easy way to switch the preferences to enable recording from the Line In socket on the laptop.
We tried muting the mic, this only caused the system to record nothing. We also tried all the various available options in "the Hardware Profiles" tab, "Settings for the available device", but no the laptop seemed to be getting no "line in" input with whatever profile we tried.
On Mac, it was as simple as switching the input sound preferences from "internal mic" to "line in".
Ubuntu :: Dies (or Freezes) Too Often On Command Line Input?
Jan 31, 2011It has been happening to me since I started to use this laptop from the company for a linux test bed. Several times a day, when I do something from the command line, for example running an application connecting to another host on the internet, etc,it comes to a freeze and does not come out of it. I can not do anything else than a forced reboot from the power button, because the keyboard and the mouse do not respond. This work laptop is a lenovo W500, running on ubuntu jaunty, release 9.04. I have not encountered this problem before with my personal laptop though. My person laptop is a lenovo X61s, running on ubuntu karmic, release 9.10Should I reinstall the work laptop with some other version of ubuntu? Could it be some hardware problem ? What tools should I use to diagnose

OpenSUSE Multimedia :: Cannot Capture Sound From Line In Input In 11.4 (no Pulseadio)?
May 18, 2011I have been searching for an answer through most of the recent posts about sound issues but have not been able to find a solution. I am currently unable to capture sound from the "Line" input on my sound card. I do have sound and is working correctly for all applications and I do have P/A disabled (I'm not a huge fan of the sound quality with P/A enabled). I have checked and re-checked many settings but to no avail have not been able to capture sound. I'm sure I may be missing something or have not done something in order for this to work. I was using openSUSE 11.4 on a different pc and had no problems, unfortunately this is a different pc with a different sound card which is on-board so I am not entirely familiar with it yet.
It is a C-media CMI9880 which shows up as a Intel HDA (ICH6) and appears to be configured correctly.

View 3 Replies View RelatedGeneral :: Capturing Remote Output Locally In Mac Terminal?
Jun 2, 2011I want local programmatic access to ssh output in Mac Terminal. First, I tried redirecting the output of each command to a file. The file was perfect, but of course it was on the remote server, and an sftp for each command output seemed a little.. Next, I tried to Applescript Terminal, but it only gives access to the currently visible text in a tab (i.e. if half the output has already scrolled out of sight, it doesn't get returned - useless).
Last, I tried piping ssh to tee (e.g. ssh user@host | tee output.txt). This almost worked. I have the output in a local file, but there are a lot of unwanted characters mixed in. For example, every time I hit backspace, there's a ^H in the file. There's also text like "[0m[K" which is harder to get rid of.
General :: Capturing And Parsing Xterm Cut Buffer In EMacs
Jan 17, 2010I'd like to make an indirect control for Emacs (in Ubuntu Linux) so that I can swipe some text in an xterm with the cursor, cutting it into the X cut buffer, then run a macro in Emacs to parse the cut buffer text to look for text saying "line XXXX" where X is all digits, then go to that line in the current Emacs buffer. I think this is possible by using emacsclient to get emacs to run a macro, then the macro parsing the cut buffer, then issuing a goto-line command to the number that's been parsed. My problem is I don't know how to write the emacs script to read the X cut buffer and parse it.. I've been going through cookbook examples but none seem to fit.
My goal is to ease development. When I have an error/information/status message printed in an xterm, I want to swipe the error message which says something like "syntax error on line 2776" then press a keyboard shortcut which Ubuntu will interpret to launch emacsclient, which causes my already-open Emacs to grab that text, parse it, and go to the line number I just swiped. Only this last step of parsing is the hard part. (Yes, I know you can run a shell INSIDE of emacs, but this is doesn't fit my workflow). How would I make emacs look at that X cut buffer and parse out the line number and issue the "goto-line" command to the current buffer?

Mar 3, 2011I have an executable with input options, like so:
Code:
./executable -n 42 -s 42
I've added gcov to the makefiles (compiling with --coverage, -fprofile-arcs, and -ftest-coverage, and linking with -lgcov). It builds fine and creates executable.gcno.
When I try to run gcov, gcov things the options belong to it:
Code:
$ gcov ./executable -n 42 -s 42
gcov: invalid option -- 's'
Usage: gcov [OPTION]... SOURCEFILE...
When I use quotes this happens:
Code:
$ gcov './executable -n 42 -s 42'
executable -n 42 -s 42.gcno:cannot open graph file
The command line options must remain. How can I get gcov to generate the same .gcno file it later looks for?
