Ubuntu :: Delete All ASCII Characters In File - Leave Chinese Characters Only
Jul 8, 2011What command could I use in terminal to delete all ASCII characters? That is, delete a-z, A-Z, 0-9, and all punctuation? I have a file containing Chinese characters, and I want to remove everything else and leave just the Chinese.
I can use grep to leave only the lines that have Chinese in them, but this still leaves a lot of non-Chinese stuff on those lines. Does anyone know how I could actually remove everything that isn't Chinese?
Ubuntu :: Compression Excluding Certain Ascii Characters?
Jun 8, 2011I am working on a project where I am dialing out of a modem!! Old stuff, ya, but the modem allows my device send info from remote sites from my datibase through a phone line so that this IT departments dont have to worry my device being a security issue on their networks.
Any way, the modem I'm using isn't incredibly well designed, and when a certain ascii char is read by the modem, it reads it as an EOF indicator. It is also important that the files I send are compressed.
My question is: Does anyone know of a compression format that allows ME to dissallow IT's use of certain ascii chars?
just as an illustration:
Device --------> Modem ---------> Off-site
and the Modem stops talking to the device when a certain char is passed to it.
General :: How To Use Extended ASCII Characters
Apr 6, 2010How can I use extended ascii characters, like ALT + 2 + 0 + 0 for instance? I'm using some of those characters for my passwords for online accounts made under MS Windows and it seams I'm unable to use them in Slackware 13. For instance: if I type ALT+2+0+0 in Pidgin there is no character displayed and if I type in the Terminal the same thing, it will replace my shell prompter (sasser@HOSTA:~$) with (arg: 200):
sasser@HOSTA:~$
(arg: 200)
Programming :: Filter ASCII Characters PHP?
Mar 8, 2010How can I filter ASCII quotes( ' ) and double quotes ( " ) so that I can replace them with the UTF-8 equivalent?If I copy text from a Word Document(ASCII), and upload it to a web page with PHP. The Database(UTF-8) will replace these racters with incorrect character(s).I need some function that will replace these characters but I don't know how to differentiate the ASCII quotes and the UTF-8 Quotes without (somehow) converting the string to hex, then preg_replace'ing the hex code for the symbol.

Apr 26, 2010Well, I have a web application in Linux server. All my Java codes are there. FYI, whenever user entered non-ASCII characters(e.g. ∞,�,�) in a text field in my web application, and I check the log of my Java code in Linux server, it returns weird characters.
Suppose user entered ∞ in the text field. I should get ∞ in my log too. However, I got weird characters in return.

Jan 16, 2010Banshee (Version 1.5.2) doesn't seem to support cover art for tracks that include non ascii characters in any way. All manual methods that work with ascii tracks failed (folder.jpg in album folder, copying appropriately named jpg in ~/.cache/album-art, embedding jpg in mp3 metadata). This is really quite a drawback for users who don't have an English-only music collection. Is there any workaround or bugfix that I missed or do I have to go back to Rhythmbox to have non-English cover art?
View 1 Replies View RelatedUbuntu :: Left Shift Key Is Ignored For Some Characters
Jan 19, 2011I've been having a strange problem with my keyboard lately. certain characters aren't capitalized when I hold the left shift. Right shift covers these buttons, but then ignores some itself.I know that it used to be fine, as I set a password on my router with a capital letter which then did not work, and in my AWN terminal, I would use ctrl+shift+v to paste in lines of code.
I am running Ubuntu 10.04 64 bit, on a Compaq Altec Lansing.For a demonstartion, here is the alphabet as typed holding the shift keys.
Left Shift
ABcDEFGHIJKLmNOPQRSTUvWxYz
Right Shift
ABCDeFGHiJKLMNopqrSTuVwXYZ

A B ce D ce F G H ,i J K L mu N .o /p zq vr S T mu vr xw xw Y zq
Also, I noticed now that I cannot use the right shift with the Left arrow key to highlight text...

View 4 Replies View RelatedUbuntu :: Bash Script - Removing Windows Return Characters
Sep 1, 2010I've got a basic script, which parses data from a text file and performs actions based on that data. Here is my code:
Code:
dsrc="/home/russellm/sites/"
ddst="/home/russellm/othersites/"
while read SiteID
do
if [[ ! -d "$ddst${SiteID:0:1}" ]]
then
mkdir "$ddst${SiteID:0:1}"
fi
mv "$dsrc${SiteID:0:1}/${SiteID%*}" "$ddst${SiteID:0:1}/" | tr -d '
' done < sites.txt
The text file came from a windows system, and contains those return characters (). I 'could' just run the whole thing through tr and then run the script on the new data file, but I'm looking for a more elegant solution. As the code above shows, I'm trying to pipe the mv command though tr in order to remove the return character - but it's not working. I can't get this to work with sed either, so I know I'm doing something wrong. I also tried to remove it using ${SiteID%} - but that also failed. The characters don't show up in an echo, just when executing a command.
Output example (emphasis mine):
Code:
mv: cannot stat `/home/russellm/sites/B/B23467324
': No such file or directory
I'm tempted to just convert the file once and call it a day, but you know what it's like. To be honest, I'm starting to suspect that there are no return characters, and that I'm going about this wrong.
General :: Bash Prompt Loses Characters?
Apr 17, 2011After writing a new prompt for Bash, I noticed that one character of my commands were being lost when it wrapped to the new line. Here is an image of the example (I typed 1234567890 over and over):

Programming :: Md5sum Bash Script With Escaped Characters?
Apr 15, 2010I created a file holding all the md5 values of my files to find duplicates as follows: find /mnt -type f -print0 | xargs -0 md5sum >> ~/home.md5
I then tried to find duplicates and do ls -l on the result in such way: cat ~/home.md5 | awk '{print $1}' | sort | uniq -c | sort -nr | awk '{print $2}' | head -n 10 > ~/top10.md5
Now I attempted to do an ls -l on the files using the command: for i in `cat ~/top10.md5`;do grep $i ~/home.md5 | while read checksum path; do echo "`echo $(printf '%q' "${path}")`" | xargs ls -l; done; done
This works well on most files, however it does not work when filenames have special letters in them that gets escaped such letters with accent etc. These become for examle 303.
Are there any ways I can use the escaped 303 strings with path names, or any better way I can do this?

General :: Bash : Pass Command Line Arguments Containing Special Characters?
Jul 14, 2010I'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 :: Bash - Using Find Or Grep To Locate Filenames With Accented Characters From A Different Encoding System (Windows)
Dec 6, 2010I tried to tag late onto a question similar to mine on stackoverflow (Find Non-UTF8 Filenames on Linux File System) to elicit further replies, with no luck so far, so here goes again... I have the same problem as the OP in the link above and convmv is a great tool to fix one's own filesystem. My question is therefore academic, but I find it unsatisfactory (in fact I can't believe) that 'find' is not able to find non standard ascii characters.
Is there anyone out there that would know what combination of options to use to find filenames that contain non standard characters on what seems to be a unicode FS, in my case the characters seem to be 8bits extended ascii rather than unicode, the files come from a Windows machine (iso-8859-1) and I regularly need to fetch them. I'd love to see how find and/or grep can do the same as convmv.

General :: Does Non-printing Characters Escape Characters Still Needed For PS1 Definition?

Aug 3, 2011This is weird, and I never noticed before, but now I have an application that is borking on weird things like when /etc/hosts is of one file format or another, and I don't even know the difference between the two (google doesn't tell much either). on CentOS 5.5/5.6 x86_64: a which on the following is an interesting tell:
vi = /bin/vi
vim = /usr/bin/vim
both are actually vim version 7.0.237 but sum differently, and although they are both actually separate executables in the stock installs of CentOS I've been building, on most distros, and older versions of CentOS it seems, vi is usually just a symlink to vim - but again, not in these fresh installs it seems. When I create a file with the 'vi' above, it defaults (usually) to "ASCII text" (but not always) When I create a file with the 'vim' above, it defaults to "ASCII English text" (and causes a particular application I'm working with to bork and barf). It seems the OS is installed by default yielding both file types too, as evidenced by the following:
