kernel 2.6, slackware 12.0mkisofs 2.01If I do 'ls --help|more' all's well. 'mkisofs --help' outputs its help screen, and I can use Shift+PgUp/PgDn to scroll through it. But I can neither pipe it to more or to less, nor redirect it to some file. more is simply ignored. Less, gets into less but only the last screenful is seen. Redirection, i.e. 'mkisofs --help>john.txt' produces an empty file (size= 0).

I am setting up rsyncrypto to create a backup of my user directory. I read that to exclude directories I need to exclude with find and pipe to rsyncrypto.
I am trying to exclude all .svn directories from getting encrypted and synced.
Here is the find command I'm using. I don't see any .svn directories in the output:
find ~/Documents -type d ( -name .svn ) -prune -o -print
But when I pipe the output to rsyncrypto I see lots of .svn directories getting encrypted.
find ~/Documents -type d ( -name .svn ) -prune -o -print | rsyncrypto -vc --trim=3 --filelist - /tmp/Documents/ Documents.keys backup.crt
rewrite the command to exclude from rsyncrypto any files/folders that have .svn in their path?
I have the following code
Code:
ls ~/ | grep ^[[:lower:]]
and would like to take the result of this output and use this as the basis for a cp command to move these files to another folder.
Let's say I have a bash script called log.sh. In this script, I want to read in input from a pipe, but I also want to know the command used to pipe input into me. Example:
tail -f /var/log/httpd/error | log.sh
In the shell script, I want to know the command tail -f /var/log/httpd/error.
I want to attach an analog camera to an old linux computer and directly pipe the /dev/video0 to another computer, where I can use it as a device again (so /dev/video0 should go to /dev/remote0, for example)
(Reason for doing this is that the computer does not have enough power to encode the video)
Is that possible? I've seen people can pipe the data directly from the device over ssh into mplayer, but I need to have some sort of reference point for Zoneminder.
I am sure this has been covered before, however I do not know which terms to sue for searching for this, so I will try and explain it.
I have a program that I run at startup to connect me to my work VPN, specifically the Cisco VPN client. When running the program, it prompts me for my username and password. I would like to be able to automate the login process by piping the username and password into the program everytime it starts up (username and password cannot be passed as arguments to the program)
Something like echo username | echo password | vpn_script
I remember there was a command that would allow me to pipe data to an app and the use the | operator to pipe it into yet another app.
foo fooArg | Iforget app1 | app2
I forget what this command is but it pipes the data from foo into app1 and app2.
I have written a script and included the command
Code:
set -x
to see what happening when i run the script

This seems so simple when doing it from command line but I'm not able to accomplish it inside a script. I am trying to put output of following command into a text file:
CMD= mysql -uroot -psecret -e 'SHOW SLAVE STATUS G;'
FIL=~/replication-`date +%F`.txt
MAILTEXT=~/mailtext.txt
touch $FIL
$CMD > $FIL
Where FIL is a variable that contains path of the file to which to output command. I am running this command in a shell script from where I want to email contents of $FIL as attachment using mutt. But I am always getting 0 byte file. Also if I examine in directory the file is of 0 byte length.
I would like to get the command and it's output redirected i have tried using the below but my syntax seems to be incorrect .

i have the following challenge: i have a Bluetooth GPS device that i have connected to my linux notebook. but now i also want to use the same device (or better, GPS data stream) for my Navigation device (HP Ipaq with TomTom). make an serial port bluetooth service (sending) that my Navigation device can connect to. copy the incoming bluetooth serial port data stream to the outgoing bluetooth serial port.
i have already installed GPSD so i have the TCP port where the GPS data is available for everything on my notebook. but now i also want it to send it out through bluetooth.
1. is there someone out there who already did this?
2. how to make an bluetooth serial port service on Fedora 12?
3. how to copy a data stream from 1 device to the next device?
I'm not sure about the following behavior so thought I would put it out to see if there is an error I need to resolve, or simply a process that I need explained.I'm also not sure if this is an Ubuntu issue, a Linux issue, or other... but here goes.I ran my "make build" in two different ways; one with just "make build" and one with "make build > output" (so I could review the full script).With just "make build" the process finished and returned to the command prompt.
With "make build > output", after the process had finished (script in output document identical to what was in the terminal with "make build") a new set of data was displayed in the terminal (see below).With the other examples of using "make build > output" the times it would parse something back to the terminal window was when there was an error. As I fixed the errors these breaks back to the terminal window would stop. So I'm wondering if this indicates a new error, but because the "make build" now completes successfully (at least it appears to), I'm wondering if this data in the terminal window is just a behavior related to redirecting the output script using the ">" process and something to do with returning to the terminal once a process completes
I have my .procmailrc file set up to pipe mail to a simple php script I've written. The only thing the script does at this point is echo back a "hello" message. However, procmail does not execute the script properly.
View 1 Replies View RelatedI have a bash script that I want to import in to Python, mainly just to see if I can or not. However in the script I do use some piping of commands into sed to trim it down to what I need. When I tried doing it with the os.system() call, it didn't work. The exact error is
sed: -e expression #1, char 16: unterminated `s' command
However the command that was run can be run in bash without an error. Is there a better/another way to do this? For reference the command is:
Code:
locate -n 1 wp-config.php | sed 's/wp-config.php/
/g' | sed '/wp-config.php/ d' | sed '/^$/ d'
New to ubuntu and shell scripting in general... currently I stored some data into a text file. Right now, I would like to output the data from the text file and store it into a variable. Here's what I have so far:
READ_FILE=$(cat $FILE_NAME)
This definitely works and READ_FILE has the necessary data. However, this command will trigger an output to std output and I will see data on the screen, which is not what I want. I tried:
cat $FILE_NAME | $READ_FILE
and various other variants of this. It does not output to std output but neither does anything gets stored into $READ_FILE. I tried:
cat $FILE_NAME >> $READ_FILE
and it arrived at an error of "ambiguous redirect".
how would you go about piping the output of the shell to notify-osd?

View 7 Replies View RelatedI am looking for an alternative to cat for streaming the output (ATSC) of a dvb card to a file. cat works fine for a bit but there is some internal variable that reaches a size limit and stops it. As evident by the c error "variable has reached size limit" (sorry for the paraphrase I do not have the error in front of me.) That is ok, a co worker who knows c told me the best thing to do is to find some other utility to do this. cat /dev/dvb/adapter0 > test.mpg is what I am looking to replace. how to pipe this into some sort of compression utility.

I want to pipe the output of a command into grep as the search TERM, rather than the text to be searched, like this for example

I have a GPS device which sends in data on port number 5000, i am able to capture the data into a pcap file using tcpdump. Now my problem is, i need to pipe the data into a text file as and when data arrives into the pcap file continuously.I did extensive search, but to no avail. been trying to solve this for the past 3 days. I use the following commands to capture and pipe the data, but that happens only once when i issue the command. I want this to happen continuously as and when the data arrives.
View 1 Replies View RelatedI need to achieve a particular effect using bash's redirection facilities.I know that I can redirect a file to some program's standard input:[user@host]$ application < file.txtThe thing is, I'd like to know can I regain control of this program's input after the file content's have been passed to it. In other words, I'd like to run a command similar to the above, and then, instead of the termination of the application, I'd want it to wait for further commands from standard input (keyboard).
As I write this question, it occured to me that I could probably write another application (or a script), that would at first write some data to standard output and then act as echo, like:[user@host]$ stdin_proxy.sh | applicationWould it work, and is there any better way to do so? There are a bunch of Googleable tutorials covering this issue, but they all amount to one advice - "reopen the stdin after the file contents have been read".
i'm trying to redirect the output of a command to the input of the next command. not sure if i'm going about this the right way. an easy method would be just to store the output of the previous command in a file and redirect input to read that file, but i'm curious to see if this can be done without writing to any files.
