I'm putting together a small bash script which uses diff in a sub shell. RESULT=$(diff file1 file2) This is the first time I've tried to return multiline output from a subshell - how can I get this to display as multiple lines instead of one?
My headphones jack is broken. I wonder is it possible to force a sound system output sound through microphone jack? As result I want plug-in headphones to microphone jack and get the sound. Or BIOS handle it?
is there a way to install Ubuntu with up-to-date versions of all packages right away? To clarify: With the normal LiveCDs, in order to install an up-to-date Ubuntu Lucid, I have to download a 700 MB LiveCD, install Ubuntu, and then use the Update Manager (or apt-get) to upgrade all outdates packages, which by now should be another about 300 MB. Old versions of SUSE Linux had the option of downloading an ~40MB installer ISO which did not contain any packages itself, but would download and install the most recent versions of all necessary packages.
Is there such a facility for Ubuntu as well? Or a way of using an outdated Ubuntu LiveCD (e.g. Lucid Beta 1) to still install an up-to-date system in a single pass? I am *not* talking about netboot images such as netboot.me or boot.kernel.org, which AFAIK will download the full normal Ubuntu ISO during boot, so that I would still have to upgrade the system afterwards.
when I am running the script below,it performs on whatever logfile u type ,i.e, ./scriptname logfilename.But how do I convert it into a function and then call it from another script.I mean how do I prompt the user to enter a logname and then capture the name in the function and when calling this function from another script how do I pass the parameter.
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.
How can I pass carriage return to a command. I am writing a shell script whcih generates ssh key pair. It ask for input from user three times. I want to pass carriage return (ie. press Enter button) to this command. Is tehre any way
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?
I'm new to UNIX scripting; I�m stuck with the following I have an Oracle SQL script that takes three parameters
1- File Name 2- File Path 3- File creation date
Under UNIX I have a folder where files will be placed frequently and I need to upload those files to Oracle, what I need is a UNIX script that can do the following
Loop through Directory "/home/applmgr/snktmp" Picks only files Pass the file name to parameter &1
[code]....
Is the above possible? I already knows how to call the Oracle Script from UNIX Im only stuck on writing the UNIX part where it List the files attribute(name,path,date) and store them to parameters ,Looping until the last file in the directory If the above is not possible,then how can I create the below from the command line
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.)

I have one distro installed, LILO as the boot loader, and i wonder if it's possible to duplicate the lilo entries with an option which executes some script or command during, or after the boot.Actually, i installed a Slackware + autolaunching virtual machine, but i have two VM, so i need to autolaunch one of them. May i choose it from the very beginning ?
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.
I am using openSUSE 10.3.When I install software from tarball then to record time required I send output of date to beg.txt(when installation begins) and end.txt (when installation finishes).How can I append output of date to a file so I don't need two files?
I would appreciate help with how to extract the date and time from at command jobs. From what I can tell, the date and time is embedded in the file name (/var/spool/atjobs).I'd be using this information in a (bash) shell script.
I want to run gsettings list-schemas (which return a list of about 100 names separated by spaces)and somehow direct each name one at a time as the input to this command:gsettings list-recursivelyI've tried it with awk, and standard | piping and also as a string variable strvar=$(gsettings list-schemas) and using the $strvar as the input butam missing something in between I'm sure like for - while or proper syntax of awk etc
I want to use the output of a previous command as a parameter to another command. For example: to know where "nice" is stored i typed: which nice output: /usr/bin/nice now the second command i typed is: ls -l /usr/bin/nice Is there a way to have a single command like: ls -l which nice ?
i need to add the date of the root of the command prompt line, i can get it show to the date for any user how do i just do it for root? and i added it to the .bash_profile file
I'm trying to write a python script that will use the current user's name when interacting. Ex: when started, it should say "hello daweefolk" when I am logged in. I've tried Code: username=os.system("echo $USER") but the variable remains empty. What is the correct code?
