i want to substitute in a file what it comes with "(" character to "('". i have tried to do it with gsub but it doesn`t go well with regular expression.
View 4 RepliesI have the following file:
Code:
1 line
...
49 test test=AA:AA:AA:AA:AA=0
I need to substitute on the line number 49, all text until =. I have used the following, but with no actual result.
sed -re '49s/^.+=//' file
and
sed -e '49s/.*[=]//' file
I have a list of 2 character country abbreviations used in the Maxmind GeoCountry database that I need to convert to the standard 3 character country abbreviation ISO 3166-11 format. I could have a long list of sed substitute statements for each country.
Code:
sed "s/US/USA/g" <file>
Is their a more elegant way to do this? Maybe an array of some sort? This substitution will be used in a bash script.
I have tried making this substitution using both of
Code:
Sed operates with no comment but does nothing. awk objects to the variables content because they include the occasional non-breaking-space. The presence of these is essential so that bash will properly distribute the content of each line to an array.
The content of "orc" and "orch" is as follows (the non-breaking-spaces show as *).
Code:
1.What character instructd the shell to interpret a special character as an ordinary character?
2.What directory contains some of the utilities available on the system in the form of binary files?
3. What command is used to search the location of a utility?
4. What command is used to instruct the editor to write the file and quit the editor?
5. What key quits the more utility and displays the shell prompt?
6. What command starts a child shell as the super user, taking on root's identity and environment?
7. Which wildcard characters can be used for searching all the files in the system that start with "A"?
8. The user name or login name of the super user is????

i have a PHP program, it encompasses about 200 scripts. Years ago, it was rewritten by another programmer to be multi-lingual, but the multi-lingual attraction of it never took off. Now that I am the only maintainer, trying to reuse what I have for code is quite difficult. If I look at one script, I see items like
_HEADER_TEXT_ERROR_4
_TABLE_ROW_SIZED_FORMAT
_ERROR_SELECT_RADIO_MAIN
All of these (and many more) are found in a "main.php" file that sort of go like this:
DEFINE _HEADER_TEXT_ERROR_4 "You Entered a Bad Value";
DEFINE _TABLE_ROW_SIZED_FORMAT "Last Name";
DEFINE _ERROR_SELECT_RADIO_MAIN "Make Your Selections";
What I would like to do is have something that says FOR all files in this directory, when you find something that starts with _, find that value in main.php and substitue what is inside the quotes for that value. Sort of unwriting all this multi-lingual stuff. I can format how I would do it if it was all stored in MySQL, but doing it from bash has me perplexed.
I have got certain files which somehow contain abnormal character "Del" "0x7f" or 177 which represents Del. And this is causing SVN to reject these files and abruptly end the process. I need to remove those characters from the file names but am not able to. find or grep do not search the files. This is how the file looks like with ls or find code...

I tried to use the command:
sed -i ''$line_number',/port/s/port/portMARKED/' file
to substitute the word "port" by the word "portMARKED" at the specific line that is saved in "line_number". The substitution happens, but it is copying my line twice... and I have no idea why... I need to make a single substitution of one word for another at a certain line in my text file. Would somebody know how I could do that?

Im trying to read a file in c++ and search for particular character for example if this is a list that I have:
Alice
Bob
David
[code]....
if the input is D, it should give David, if its B, gives bob. so in this case, meaning it reads the first character of every line. but if possible I want to make this dynamic so the user can specify which character position he is looking for, so in case he is looking for R as character index 3 in all lines, it should give Charlie. but the problem is, it does now recognize , besides, I do not know how to specify the character position in each line.
here is my code
Code:
#include <iostream>
#include <fstream>
#include <cstring>

I need some software that will check .xml file and tell me which character is malformed in 'utf-8'. I am using perl for some parsing.
View 2 Replies View RelatedI have a script that looks like:
Code:
cat servers.txt
trivia:P:N
trivia:D:N
tucana:P:Y
[code]....
I want to be able to find the lines that matches my input and change the N to a Y, but only for the lines that matches the name and not any other N's My problem is the line does not always contain a P as it can be a D as well so my matching did not work. If my script issues the name $1=triva the lines will change to:
Code:
trivia:P:Y
trivia:D:Y
I have the following code so far but as you can see it does not change the D's
Code:
sed -i 's/trivia:P:Y/trivia:P:N/g' servers.txt
*** UPDATE ***
should I be using a method as follows? I am still stuck on the changing all instances though.
Code:
$1=server
sed -i 's/$server1:P:Y/$server:P:N/g' server.txt
sed -i 's/$server1:D:Y/$server:D:N/g' server.txt
In my command prompt I did:
Code:
sed 's/://' mytextfile > newtextfile
But it only deleted the first instance of : in each line when some lines have multiple : appearing in each one. How can I delete all the : from the entire file?
I am trying to copy a large number of files from a Linux server to a Windows file share. Unfortunately, all of the files and folders I have to copy have 10 numbers followed by 2 colons "::" in the name (example: 1234567890::WordDoc.doc) which of course is invalid in windows naming conventions. So now I'm trying to come up with a way to change the file and folder names on the fly to replace the colons with a dash "-" or space " ". I'm even willing delete the frist 12 characters in necessary. I have tried cp, mv, tr, and several -bash scripts but get no positive results.

I was messing around with the alternate character panel app and made a custom character set. I then wanted to put it on a new panel and created a new panel. I moved the character set to that panel, and then started to mess around with the panel settings (auto hide, show hide buttons, and expand, to be specific.) So far so good, until I moved the panel from the right side of the screen to the top. I already had a panel here, and it seemed not to like hiding a panel when there was already one on the top.
When the new panel hid itself, all my panels stopped responding (any clicks on them did nothing) and my processor started going at 100%. I tried a reboot and the only thing that changed is that now I can't even see my panels. I'm guessing I need to change the settings back manually through the prompt, but I don't know how to do that. I am using 10.04 and have not upgraded gnome since upgrading to 10.04.
