General :: Pass Response As Command Parameter?

Mar 10, 2010

I have a backup schedule running a full backup everyday. I'm using webmin to manage these backup now. The problem is when the dump command sends a prompt asking if we want to rewrite the tape, Webmin does not display this prompt and we end up having to terminate the backup -> erase the tape(which takes a long time) and then run the backup again.I was wondering if there is a technique that could be used to pass "Yes" as a parameter to the dump command, much like in windows? or if there is a more efficient way of getting this done.

General :: Provide Response To Command Output ?

May 4, 2011

I am writing a bash shell script on RHEL. I need a way to analyze the output from a command, and provide a response to that command depending on what is found.

On the command line this looks like:

In other words I want to script this - capture the output from the mlsmailbox --delete command, respond with a yes if the mailbox was found, and go on if it was not found. There may be other responses to the mlsmailbox --delete command that I need to analyze and respond to as well.

General :: Pass Multiline Output Of A Command Into 'date -j'

Mar 3, 2011

I am doing some NSCA log parsing and I want to get an output like this:

I have tried this, but it treats the entire output as a single line, then plops a timestamp on the end (I think):

Code:

sort -b -k4.9,4.12 -k4.5b,4.7Mb -k4.2,4.3 -k4.14,4 foo.log| date -j -f "%Y-%b-%d:%T" "+%s" "`awk -F '[ [/:]' '{print $7"-"$6"-"$5":"$8":"$9":"$10}'`"

General :: Fetch File From There (which Is .tar.gz) And Pass It Directly To Tar Command?

Jun 25, 2010

I have access to backup server via rsync protocol (only rsync, nothing else). Now, I want to fetch file from there (which is .tar.gz) and pass it directly to tar command, without saving the archive in local filesystem. To visualize, with ssh access I could:

ssh remote_host cat backup.file.tar.gz | tar xzf - And I will get uncompressed backup locally, without actually storing .tar.gz on local machine. Is it possible to achieve when using rsync?

General :: Bash : Pass Command Line Arguments Containing Special Characters?

Jul 14, 2010

I've written myself a linux program "program" that does something with a regular expression. I want to call the program in the bash shell and pass that regular expression as a command line argument to the program(there are also other command line arguments). A typical regular expression looks like "[abc]_[x|y]".Unfortunately the characters [, ], and | are special characters in bash. Thus, calling "program [abc]_[x|y] anotheragument" doesn't work. Is there a way to pass the expression by using some sort of escape characters or quotation marks etc.?

(Calling program "[abc]_[x|y] anotheragument" isn't working either, because it interprets the two arguments as one.)

General :: WPA2 - NetID And Pass - Wireless Network From Wicd And/or Command Line

Sep 23, 2010

The university I go to uses a WPA2 wireless network that requires a netID and password to connect too. I installed wicd but I can't seem to connect to this network, is there a way to add this functionality to wicd, and if so, how do I do that (links to a how-to or guide would be nice, I've yet to find one).

Also, I spend most of my time on campus in the command line, so I'd like to know if there is a way to use command line utilities to connect to this network (again, a guide or how-to would be nice)

I can get online through my fedora live USB just fine (w/ network manager) but I'd rather get on directly from slackware.

Programming :: O_SYNC Parameter In Open Command?

Jul 9, 2010

I have a small board that has a static ram board attached to it. I have two different programs that each write to a byte of memory in the static ram board. I get a file descriptor to the device memory with the following code:

int phymemfd;
phymemfd=open("dev/mem, O_RDWR | O_SYNC);

This opens the physical memory for both reading and writing. Next I get a pointer to the beginning of my ram board.

volatile unsigned char *novram;
novram = (unsigned char *) mmap(0, getpagesize() * 31,
PROT_READ|PROT_WRITE, MAP_SHARED, phymemfd, 0x11AA0000);

I do this same code in two processes that are both running and this works fine. Now, if I take out the O_SYNC parameter, one of the programs gets into some sort of weird state.My understanding of the O_SYNC parameter is that it cause the process accessing the memory location to block, not allow another process to run, until the first process has finished writing to it.I can see that if my program doesn't block, I wouldn't really know what was in the memory location, but would I can't see how it would cause any other type of system problem.

Software :: SCP Error: Unrecognized Configuration Parameter Permitlocalcommand When Run ANY Type Of Scp Command

Jan 31, 2011

This started happening about 2-3 weeks ago when i noticed our backups weren't running anymore. whenever i try to run ANY type of scp command I get the following error: warning: Unrecognized configuration parameter permitlocalcommand ssh: FATAL: Illegal -o parameter "PermitLocalCommand no" lost connection

I checked the /etc/ssh/ssh_config file and there was a command PermitLocalCommand commented out, but for testing I even totally removed that line and then in scp forced the use of that file via scp -F /etc/ssh/ssh_config ......

and I still get the same error. This command is nowhere is any of my ssh config files so im at a loss here on how im supposed to fix this!! I even checked my home directory for maybe a ssh config file that might be overridding the system config but nothing.

Ubuntu :: Capturing Command Output Response

Aug 5, 2011

I run a 3rd party command line utility and it works fine, but sometimes it says "Error blah blah blah... Connection timed out"

I want to script this utility, but I need to not execute the commands in the script if it gives me that connection timeout error.

bash code to capture that response from the utility? Something along the lines of:

Quote:

#!/bin/bash
3rdpartyutil > /tmp/temp.txt
if [ ! -f /tmp/temp.txt]; then
echo no error, run whatever you need to man
fi
rm /tmp/temp.txt

Unfortunately, that doesn't work because the utility outputs non-error information to the screen even when it is successful, so it always outputs something, I never need to see it, but I do need to be able to act upon if some of that text says "error" or "connection timed out"

Programming :: Pass An Expect Command Result Into A Variable And Then Use It Again?

May 4, 2010

I'm trying to create a program that would locate the oldest file of a certain type on a server. Here's the commands:

OLDEST_PATH=`find -L / -depth -maxdepth 6 -mindepth 6 -type d | sort -f | head -1`
OLDEST_FILE=`find -L $OLDEST_PATH | grep .mp3 | sort -f | head -1`
ls -al $OLDEST_FILE

I'm writing this all in expect but I'm having problems. The main problem I have is whenever I try to run the first command, I can't seem to isolate the result of the OLDEST_PATH so that the 2nd command will work. There always seems to be a newline in the variable and the result is only "find -L" command running and it bypasses the variable. If I can just figure out how to get the 1st and 2nd command to work, then I can figure out the 3rd. Here's some code:

Code:
send "find -L / -depth -maxdepth 6 -mindepth 6 -type d | sort -f | head -1
"
sleep 20
expect -re "(.*)

[Code]....

I know there is a better way to write this. I've tried multiple ways and this just happens to be the last way I've tried it. If you try running this, you'll notice that there is still carriage returns after the result of OLDEST_PATH and it prevents the 2nd "find" command from working properly.

Programming :: Udev Rules - Pass ATTRS{*} Values To The RUN Command?
