I'm trying to make a webpage that will display the bash variables I have in a file. These variables are used in a bash script that is run from on my server.The file looks like this:

Can I have a custom delimiter for hash in perl?

any way we can change the delimiter that uses grep?
I think, by default, grep uses as the delimiter.
I have 70 folders as an output form some software they are called folder1, folder2 folder70. I want to find a way to automatically copy the contents from each folder to one big folder? So all the files are in one folder without the directories? I was thinking of something using the mv command but I'm not sure how to do this. Ok I think I have answered my own question. I did this:
# cp folder*/* bigfolder
I used cp in case it went wrong, it worked so I deleted the previous dir's.
I just got 512M RAM so i thought to switch off all the programs that i most likely will not need. The big ones, i think might be, gdm, gnome, metacity. I think a plain X will suit my purpose.
View 10 Replies View RelatedI'm working on my ncurses application, written in C. I get user input through a loop which uses getchar(). I was able to recognize Ctrl-n by comparing the keypress to ASCII character 16, and this seems to work fine. However, if I noticed that the ASCII character for Ctrl-j (10) is the same as the Line Feed. I tested this, and if I press enter on the keyboard I get the same ASCII value as when I press Ctrl-j.
So, what do I do if I want Ctrl-j to mean something different in my program than pressing enter?The ncurses terminal mode is set to raw, with a 100 millisecond timeout, and keypad is on (I'm already using the up and down arrow-keys).

I see I'm finally posting an AWK question rather than an answer for a change I wanted to make an AWK script that would scramble all the characters in each field, but leave the first and last characters where they were.

View 3 Replies View Relatedsplitting a string by every nth characters. I'm using Python 2.7.1 because I'm using older libraries, if that matters.
For example, if this is my input:
Quote:
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac elit nibh, vitae venenatis ligula. Vestibulum a varius turpis.
Splitting it by every 10th character should produce this list:
Quote:
[ "Lorem ipsu", "m dolor si", "t amet, co", "nsectetur ", "adipiscing", " elit. Sed", " ac elit n", "ibh, vitae", " venenatis", " ligula. V", "estibulum ", "a varius t", "urpis." ]
I wrote a java program that writes strings to a file. The strings contain foreign language characters. When I run the program in Windows, the output file shows the foreign characters. However, when I attempt the same operation in Linux, the output file shows a white question mark in a black background instead of the foreign characters. The same Linux system could display the foreign characters if I copy the output file from Windows to Linux. I tried to create the output file using gedit that my program would then add additional strings to and chose Unicode-32 for encoding but still the same problem.
What could I do to get the program to display the foreign language characters from output text file?
My goal is to send escape characters from Linux to make scanner's LED blink. I've started with a simple "beep" command:
echo -e "�7"
and it worked. We are using WaveLink emulator and the escape sequences for the LED are
echo -e "�33%150;200;5L"
Linux returns me this: 150;200;5L
So, it doesn't work. What am I doing wrong for the LED sequences?
How 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.
View 8 Replies View RelatedI am working on an application that will convert English text into equivalent Indian language text. Since Unicode is the standard, I will be using it. In most of the western languages each code-value directly refers to the glyph index and placing the code-values side by side will give the required display. This one to one mapping is not possible in Indian languages where rendering syllables is required rather than rendering just consonants and vowels. Many of the complex characters are made up by combining several unicode values.
My question here is: How Linux renders this Unicode text correctly? More specifically, what package is used? I believe in Windows they use Uniscribe for rendering.I believe there will be an operating system library for handling the text rendering. Or do I need to write my own rendering engine? How programs like Firefox, GEdit shows unicode text? Do they also have proprietary engines for correct rendering?
For example, I have a file called "file" like this one:
type=strongsubj len=1 word=absolve pos=verb stemmed=y priorpolarity=positive
type=strongsubj len=1 word=unique pos=adj stemmed=n priorpolarity=neutral
type=strongsubj len=1 word=absolutely pos=adj stemmed=n priorpolarity=neutral
type=weaksubj len=1 word=taking pos=verb stemmed=y priorpolarity=positive
type=weaksubj len=1 word=friend pos=noun stemmed=n priorpolarity=positive
type=weaksubj len=1 word=usually pos=adverb stemmed=n priorpolarity=positive
type=strongsubj len=1 word=purecolor pos=anypos stemmed=n priorpolarity=negative
type=strongsubj len=1 word=accusingly pos=anypos stemmed=n priorpolarity=negative
I want to add the plural for the noun, for example if find this line:
type=weaksubj len=1 word=friend pos=noun stemmed=n priorpolarity=positive
will add one more line :
type=weaksubj len=1 word=friends pos=noun stemmed=n priorpolarity=positive
where we add "s" for the word friend
I did try to do like that:
<code>
cat file | while read LINE ; do
set -- ${line}
if [[ "${4#pos1=}" == "noun" ]];then
#I tried this line but it doesn't work properly:
v3==$(echo $line |sed 's/$3/$s') #I want to find the third word "word=friend" in that line and add "s" after that word
# I don't know what command to add this new line "$v3" to the file ???
done

Well, 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.

I have looked inside and out of KMail, and for the life of me, I cannot seem to find out how to make KMail maintain HTML formatting and keep the images when REPLYING to sender or FORWARDING an email to another or others. Does anyone know a tweak to make KMail Replies and forwards to stop convert everything to plain text and strip the images? I live in a family where we all share parody, etc. emails, and plain text rarely ever cuts it. I did not suffer such with Thunderbird.

Currently, I'm working on personal project. and I'm kinda stuck. What I want to do is that open a file, and edit that file (deleting unwanted characters). The problem arises after I deleted unwanted characters, the file still has the same length of the original one. Let's assume that we have a file with "1234" in it. I deleted "3" ( I overwrite "\0" ) so now when I check the file, it's 124. But when I check the length, the both have the same size as 4
Here is an example source code
int length, length2;
num = open("a.dat", 2)
length = lseek(num, 0, 2); // Initial length
lseek(num, 2, 0); // editing
write(num, "\0", 1);
length2 = lseek(num, 0, 2); // Final length
close(num);
When I print those values those are exactly the same. Length2 should be one less than length, but the both are 4. What's wrong in m code? Am I supposed to use different character rather than "\0"?
I have a hard time figuring this out. I need to replace the date formats of arrival date(column 31-40) and departure date(column 42-51) and I need 2 outputs. I cannot even figure out how to start.code...
