I am having difficulty getting sed to replace a string of text in an XML file, despite the fact that I have no trouble using grep to find that same string. Since the new string and old string to be replaced contain a lot of special characters, I thought it best to store them in variables as opposed to using a slew of backslashes:
But the problem is that in this case i just wanted to append "/home/dest" for which I could easily escape "/" with just two "", but I wonder if i have a long path like "/a/b/c/d/e/f/g/h/i/j" I will have to escape so many /. Is there any other way by which I can avoid escaping forward slash.
I tried following:
But receiving follo error
Bareword found where operator expected at -e line 1, near "s/destination-path=/'destination-path=/home" syntax error at -e line 1, near "s/destination-path=/'destination-path=/home" Bad name after dest' at -e line 1. tried with enclosing in double quotes as well but in vain
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.)

While modifying the definition of my PS1, I saw that "[" and "]" markers should be added to help bash to compute the right display lenght. Many exemples on the web do not use them or even mention them.I searched for a solution to add them automatically, like with sed, but I didn't find any example.Are they still needed and is there a recommandation not to use sed to define PS1?
Need little advice running this command. watch -d 'ps aux | awk '{print $4" "$11}' | sort | uniq -c | awk '{print $2" "$1" "$3}' | sort -nr | head'
I get this error message from AWK. awk: cmd. line:1: {print awk: cmd. line:1: ^ unexpected newline or end of string
I have tried all the usual by trying to escape the single and double quotes in the command but same result. The end result should be the a listing of memory hungry processes that are scanned every 2 seconds (watch default value).
Is it possible to remove the ESC sequences in GNU Screen's output file? Things such as colours, tabs and other escape characters make their way into the log files and become difficult to decipher.
I've tried Dr. Google & Co. as well as reading the manual, but haven't been able to find anything suitable.Perhaps I've overlooked something?
Is there tool or a regexp that can convert shell escape characters to HTML code?
As an example, here is a logfile from GNU screen:
Which I would like to convert to something like this:
And send as HTML e-mail to an e-mail address, to archive my work.
Here is a related question, which shows how to convert it to regular text, but it would be nice to convert to HTML and not just throw the escape characters away.
Simple logging script that allows user to enter quick notes and questions, but I can not get it to pass punctuation '?. no matter what I type after 'n' i need that to be inserted at the end of the working project note file.Any help and working examples would be appreciated, but please also direct me to the proper reading material so I can learn something - not looking for someone to just do it for me.usage:
I am trying to make specifically Norwegian characters appear properly. Right now they look like this:
[URL]
Characters like turns the same. This is a font that I downloaded called PT Sans. The letters I want are included, they just don't appear right in the GNOME environment, it seems. They work just fine in other applications, such as OOo Writer. I'm using Ubuntu 10.04.
I want to archive all .ctl files in a folder, recursively.tar -cf ctlfiles.tar `find /home/db -name "*.ctl" -print`The error message :tar: Removing leading `/' from member namestar: /home/db/dunn/j: Cannot stat: No such file or directorytar: 74.ctl: Cannot stat:No such file or directoryI have these files: /home/db/dunn/j 74.ctl and j 75. Notice the extra space. What if the files have other special characters? How do I archive these files recursively?
I am running gentoo openbox(rox file manager and desktop) I installed Digikam and Amarok. But I have problems with files which include special character in their names(such as �,�, �,ğ... ) The files are shown with strange and weird characters in the file dialogs of Digikam and Amarok.
I don't have this problem in other applications. I can create files with special character included. I think some settings do not agree with KDE4. How can I solve this problem? Does anyone have an idea? I also installed KDE systemsettings program but could not find a relevant config option for character encoding.
We are creating PDFs from different sources using PHP, Zend_PDF class and Zend server (based on apache2). Developping on windows the PDFs are OK. If we deploy the application on testing server running SuseLinux the special characters ( ) don't show. We use 1 of the standard fonts, HELVETICA and have tested without success COURIER.
The system
Do you have an idea what to do or try?
OK - it turned out to be a coding question. I had thought that some system variable might cause the problem but we simply had to clean the input data and got it working.
I need to search for the following pattern with GREP in a text file:
So I tried already:
But none of those works...I think probably because GREP doens't like the special character > in the middle of the serach pattern.
At the end I just need to now if GREP found the pattern in the file or not, so it should give me a 0 or a 1 back, once I check the value of the variable "?" after using the grep command.
The command tar -xvf wpa_tables.tar gives this error
tar: ./xai-0/334Regency: Cannot open: Invalid or incomplete multibyte or wide character tar: Exiting with failure status due to previous errors
Obviously the backslash is giving tar some problem, but I've been all over the docs and can't figure out how to either make it skip this file or interpret the character literally. Here's my command history to show some of the options I've tried which don't work.
tar --no-wildcards -xkvf wpa_tables.tar tar --exclude ./xai-0/\334Regency -xkvf wpa_tables.tar tar --exclude "./xai-0/\334Regency" -xkvf wpa_tables.tar tar --ignore-command-error -xkvf wpa_tables.tar tar --ignore-failed-read -xkvf wpa_tables.tar tar --transform 's/\/slash/g' -xvf wpa_tables.tar ./xai-0/\334Regency
I'm totally out of ideas at this point and would welcome some input from more experienced members.
We're in the process of implementing an offsite backup of all our servers to a remote Linux server. We're using rsync over ssh.What I've found is that characters such as ±, ¶,´ and £ are replaced on the Linux server with underscores.I don't mind if it changes these characters in the filenames of documents, but when it renames a language pack from Espa±ol.clx to Espa_ol.clx, it could cause issues for us further down the line.
What do I need to do differently to make the special characters copy over correctly? For the initial sync which will take place locally, before the machine is moved offsite, I have SAMBA enabled. I am able to copy files from Windows to the Samba share, retaining the original filename, though it looks different in the Linux directory listing, i.e. t̻st becomes ĻstThese files get deleted by rsync when it runs, as it does not match the filenames.
I am dragging my files over to a new Fedora 12 installation and I just noticed that special characters are not taken into account when sorting files by name (I want '_js' to come before 'images').Is there a way to make the sorting process behave like Windows, where files starting with a special character are listed first?
I have txt file with list of ID's and I need to insert comma in every line and then remove new line character so it'll become one long string. So to clarify, I have txt file content that looks like this.
234 5466 2356 ... and so on.
but I would like this to change to 234,5466,2356,... I looked at sed and tried to wrap my head around the commands but I guess my brain isn't smart enough. its really confusing for me. I've managed to add commas to end of line (sed "s/$/,/g" filename) but somehow I can't seem to remove new line character from each line.
My question is: what option can I set in vim to see the colouring inside the editor as I would get it in my terminal (and switch off any additional syntax highlighting)?
dhclient does not strip or escape shell meta-characters
Summary: dhclient doesn't strip or escape certain shell meta-characters in dhcpd responses, allowing a rogue server or party with with escalated privileges on the server to cause remote code execution on the client.
CVE:
ISC dhclient did not strip or escape certain shell meta-characters in responses from the dhcp server (like hostname) before passing the responses on to dhclient-script. Depending on the script and OS, this can result in execution of exploit code on the client.
CVSS Score:
For more information on CVSS scores, visit [url]
Workarounds:
On SUSE systems, it is possible to disable hostname update by setting DHCLIENT_SET_HOSTNAME="no" in /etc/sysconfig/network/dhcp.
Other systems may add following line to dhclient-script at the beginning of the set_hostname() function:
In environments where filters/acls can be put into place to limit clients to accessing only legitimate dhcp servers, this will protect clients from rogue dhcp servers deliberately trying to exploit this bug.
However, this will not protect from compromised servers.
Active exploits:
Solution:
Upgrade to 3.1-ESV-R1, 4.1-ESV-R2 or 4.2.1-P1. [url]
No patch is available for 4.0.x as it is EOL. Anyone running 4.1.x should upgrade to 4.1-ESV-R2.
I am trying to type German Umlaut letters on an English keyboard using kde 4.4. For some reason I seem unable to figure out how to do that (I have just recently switched to kde, was using gnome before). I have looked through various threads and the kubuntu wiki [URL], but can't get the compose key to work. In gnome I used to type "AltGr" plus "[" followed by a vowel and thus get my Umlaut - before I fiddled with the system settings this worked in kde, but only in firefox & Open Office (I assume they are gtk apps).
Since it did not work in Kmail, I went to the system settings, set up a ComposeKey (AltGr, but also tried rightWin), but it doesn't change anything for the kde applications. It only means that the old key-combination now stopped working in firefox and OO. In the system setting of kde 4.4 I can't see the options to enable xkb-options, but I assume the advanced options of the keyboard layout are xkb-options of previous kde releases. I unticked the box 'reset old options', but nothing changed. I type a lot of German text, so using a character map is not an option.
