• Diff and ignore lines missing in one file

  - by Millianz

  I want to diff two files and ignore lines that are present in one file but missing in the other. For example File1: foo bar baz bat File2: foo ball bat I'm currently running the following diff command diff File1 File2 --changed-group-format='%>' --unchanged-group-format='' Which in this case would produce bar baz as the output, i.e. only missing or conflicting lines. I would like to only print conflicting lines, i.e. ignore cases where one line is missing from File2 and is present in File1 (not the other way around). Is there any way to do something like this using diff or do I have to resort to other tools? If so, what would you recommend?

• UDISKS instead of HAL

  - by MeJ

  Does anybody have some expirence with udisks, because HAL won't be longer supported on the most linux distribution, so I am thinking of to use udisks for UDI in $(hal-find-by-property --key storage.bus --string usb) do HAL_TMP=`hal-get-property --udi $UDI --key storage.removable.media_available` if [ "$HAL_TMP" = "true" ]; then HAL_DEV=$(hal-get-property --udi $UDI --key block.device) HAL_SIZE=$(hal-get-property --udi $UDI --key storage.removable.media_size) HAL_TYPE=$(hal-get-property --udi $UDI --key storage.drive_type) How do I have to adapt the above mentioned commands but use udisks instead of hal Thanks!

• trouble using a scheduled task to run a shell script (ubuntu linux)

  - by John Kube

  I'm trying to create a scheduled task that runs a shell script recurrently, and I'm having some trouble getting it to work. I give it the following command to run every minute: ~/Desktop/foo/my_script But it doesn't ever run. (This command runs the shell script through the terminal no problem.) Any ideas what I'm doing wrong? Thanks!

• stdout and stderr of script doesn't get redirected when executed by cron

  - by gletscher

  Hi, when I execute ./script &>> log.txt I get a nice logfile, but if I have the same command executed by cron, lets say the crontab looks like this: * * * * * '/home/user/script &>> /home/user/log.txt' the log.txt will just be empty, I tried " and ' and ` and no ticks to enclose the command, any idea why the streams won't get written into the file?

• cut text from each line in a txt file

  - by bboyreason

  i have a text file where each line looks like this: <img border=0 width=555 height=555 src=http://websitelinkimagelinkhere> each line is like that for like 1500 lines, i want to sort of 'grep' (i dont think that will work because it returns the whole line) each line for 'http://websiteimagelinkhere' output file should have newlines or tabs after each image link, like the original file. or if someone only knows a way to do this with each element being in a cell of the same column that would be okay too.

• Automake thumbnail

  - by Webmaster

  What I need to do is a program that given (as a command line argument) a directory with more directoreies inside, and 4 Pics inside of each dir, the program makes a thumbnail of the 4 files and glues them together (2 rows, 2 columns) and renames that image to the name of the directory. I think it could be done with a combination of a program and shell scripting (I'm experienced in M$, but new to linux). Some real examples would be great. Thanx in advance

• using "touch" to create directories?

  - by user66732

  1) in the "A" directory: find . -type f a.txt 2) in the "B" directory: cat a.txt | while read FILENAMES; do touch "$FILENAMES"; done 3) Result: the 2) "creates the files" [i mean only with the same filename, but with 0 Byte size] ok. But if there are subdirs in the "A" directory, then the 2) can't create the files in the subdir, because there are no directories in it. Question: is there a way, that "touch" can create directories?

• Using watch with pipes

  - by Tom

  Hi! I'd like to run this command: watch -n 1 tail -n 200 log/site_dev.log | grep Doctrine But it does not run, because "I think" that the grep tries to run on the watch instead of the tail... Is there a way to do something like watch -n 1 (tail -n 200 log/site_dev.log | grep Doctrine) Thanks a lot!

  I'm want to use adduser However it doesn't seem to work if I provide the second argument for the user's group root@a:~# adduser rick staff adduser: The user `rick' does not exist. The group exists root@a:~# addgroup staff addgroup: The group `staff' already exists. The man page says this should work... adduser [options] user group Any ideas? I can do: adduser --ingroup staff rick So no massive issue, just seems strange.

• Change to different user, or let different user execute a command

  - by WG-

  I have a problem. There is a server which I can access with an account by ssh, lets say WG. Now there is a folder with the following permissions. drwxr-s---+ 855 vvz www-data 20K Aug 21 17:56 pictures I want to copy this folder using rsync, however since I am not the user www-data but WG I cannot execute rsync. So I want www-data to execute a rsync command. However, I do not posses sudo powers. My friend however tells me that I am actually able to execute the rsync command as www-data, but he will not tell me how. I asked him for some clues and he told me that it had something to do with reverse shell (which I figured out to be that you connect by ssh to your server and then you connect back to your own server, or something). I also asked if it was by-design or actually a flaw in the system. He tells me it is both. Furthermore I think it has something to do with the group permissions. If I just make sure that I am with the group permissions then I can also read the files. Anybody has a clue?

• log execution of certain commands on linux

  - by jlsksr

  I have to maintain a system (debian) on which several users are allowed to install programs - so I would like to log, for example, if anyone executes "apt-get install" or "apt-get purge", so I can keep track of manually installed packages.. I'm looking for a general way to achieve this; it's not just APT, but several programs/scripts etc. Any ideas? /edit a google-search with few different keywords brought up this: http://serverfault.com/questions/201221/how-to-log-every-linux-command-to-a-logserver http://stackoverflow.com/questions/15698590/how-to-capture-all-the-commands-typed-in-unix-linux-by-any-user http://sourceforge.net/projects/rootsh/

• How to cd into smb://[email protected] from terminal?

  - by John

  I am using ubuntu and gnome on my computer. When I open up File Browser, on the left hand rail, I see conveniently a folder called "Work Server". When I mouse over it, the following caption appears "smb://[email protected]". If I click on that folder, then I can see the contents of that folder. Everything is great. So now when I open up a terminal/shell, I type in cd smb://[email protected] I get an error saying the directory doesn't exist. How do I enter this directory via shell/terminal?

• How can I automate or script daily downloads for any new anti- virus databases, and then have the program scan my drive?

  - by Macgrimm

  Howdy all Super Users" I humbly ask if any Super User can direct this long time, gray haired Apple Tech in the right direction on this issue. I believe there probably are many ways to skin this cat. But I am looking to find simply the best, most unattended way to get it done. Any help will be greatly appreciated. also (I know there are much better softwares out there for the Mac so please don't go there! The politics of this company dictate which Anti virus we have to use) anyway without any further wait: basically I am trying to automate 2 very important functions of Mc'Afee anti-virus for Mac. First I want to automate the process of retrieving new virus definition files, and second I want to automate the process of scanning for viruses. It turns out that Using Mc'Afee Anti-Virus for the Mac are both manual functions. And they left up to the user (per user account) to perform. Depending on all of about 150 MAc users to perform these 2 tasks themselves is around 65% compliance. My question then is: If I wanted to use the command line such as (open /Applications/McAfee\ Security.app) It will open up the Security Console. But how can I make command Mc'Afee go out and grab the definition files and scan the computer? I have to admit I am at a crossroad and Macaltimers has set in. I would really appreciate it if any of you "Super ~ Users" can help me out with this MacAltimers loss of how to what to do. Thanks to All up Front Macgrimm

  - by gojira

  According to the screen manual (version 4.0.2.) C-a x C-a C-x (lockscreen) Lock this terminal. C-a X (remove) Kill the current region. But what actually happens when I use it (Screen version 4.00.03 (FAU) 23-Oct-06): C-a X locks the terminal and asks me for the password. When I enter the correct passwword, I am back in screen but the region is killed (wtf) C-a x does nothing apparently Please note the differences between x (lowercase) and X (uppercase). Why is there a mixup between the functionalities of C-a X and C-a x? How can I fix this? I am on CentOS release 5 (Final).
