Programming :: Sed - Save Output To File With Filename From Content Of Another File?
Feb 28, 2011My employer issues pdf files with everyones work schedules. I copy the content and save it as plain text in a file called unformatted (hope to be able to automate this step someday). Im working on a SED script that reduces unformatted to only display what I want to see and saves the result in a file Iïve named formatted. After that I have to manually copy formatted and save it with that days date as a filename e.g. 2011-02-25 or whatever day is scheduled in the pdf, for use on a mobile device (Nokia N900). I noticed that the date occurs on certain lines in the file so I added a line like:
sed -n 's/^Date: (201[1-9])/([0-1][0-9])/([0-3][0-9]).*/1-2-3/p' < unformatted >theDate
That creates a file theDate with the date in it that I wish to use as the filename for this particular instance. So I would like to skip the file formatted all together and have the sed- script write to a new file using the content of the Date as a filename, but how do I make that happen? And of course it would be more elegant if I could skip the intermediate theDate file as well.
Programming :: How To Redirect ALL Output To (log) File?
Aug 6, 2010I am again struggling to make a script work, but hey, it is fun, I am learning new things. I discovered the set -x option which was, for me, like the second coming. Still, what I am not able to do is redirect ALL output to a (log) file, including what is produced by the -x setting. Let's assume a very simple script:
Code: #!/bin/bash
set -x
source="/home/atelier/Bureau/"
ls -la $source and I am running it as . test.sh >> /var/log/test.rmcb.log
The result of ls goes inded into the log file, but the rest still shows on the console where I am running the script: Code: ++ source=/home/atelier/Bureau/
++ ls --color=auto -la /home/atelier/Bureau/ Is there a way to redirect EVERYTHING to the log file ?

Programming :: Bash - Redirect All Subsequent Std Output To File?
Feb 11, 2010I have got a script with an outer and inner loop. The inner loop issues loads of echo's which need to be redirected to a log file determined by the outer loop. The obvious solution is to redirect every echo to >$LOG and set LOG in the outer loop.

LOG=<logfile>

it is possible to map stdout to $LOG in the outer loop without having to redirect every subsequent individual command output?

Programming :: PyGTK: Send Output From A File Descriptor To A Textview?
Jul 22, 2010Within PyGTK I'm using gobject.spawn_async to launch a bash script. I would like the output of that bash script to be displayed within my application. I have a textview set up to receive the text ...
Here are the commands that launch the program:

def run_command(command):
global keep_pulsing
keep_pulsing=True
(cpid, cstdin, cstdout, cstderr) = gobject.spawn_async(command,flags=gobject.SPAWN_DO_NOT_REAP_CHILD|gobject.SPAWN_STDERR_TO_DEV_NULL,standard_code....
Here are the two callback functions. But like I say ... I have no idea how to get that data from the 'cstdout' file descriptor into a textbuffer.
Code:
### THE FOLLOWING ARE GLOBALS:
textview = wTree.get_widget('textview1')
textbuffer=textview.get_buffer()
def update_textview_callback(fd, condition):
global keep_pulsing

Programming :: Find Command With Standard Error Output And Mail Error File
Nov 11, 2010We make everyday a DB Mysql backup on Linux redhat Enterprise. We are using a bash shell script (and putting it in the crontab) to execute it automatically everyday. We added a line to this script telling, once the backup has completed, to find old backup files (stored on hard disk after each backup) older than x days to remove them. We use the find command (search for file type) with the mtime option and in combination with rm command. Everything runs ok but we also want to add some new code to the same line: If find command cannot find anything or fails, for example if it cannot delete file or fails, send the error message (standard error output) to an error file (like error000001 and increasing) and mail the errorxxxx file to an email address for example to admin@companyname.com. What would be the code for this issue to add it to our find command in the same bash shell script??

Ubuntu :: Pdftk Output File With Pages Extracts Same Size As Input File?
Apr 22, 2011I am curious if perhaps I am doing something wrong extracting pages from a pdf doc using pdftk and creating a new file. I am only extracting the odd pages from the file and outputting them to a new file that is now only 20 pages instead of the input's 40 pages, yet the new output file is still 1.4Mb in size, the same as the original.
It seems strange to extract only half the pages of a large document and end up with a result that is the same size. how to streamline the resulting pdf's using pdftk?
BTW this is the command I am using, in case perhaps I am missing an option to optimize file size or something:
Code:
pdftk A=ch15.pdf cat A1-40odd output odd.pdf
