Programming :: SH: Remove Last Char If It Is An Empty Char In A String

Jul 5, 2011

With this I may remove the last emtpy char which is not visible, coming from net, windows, ...

Code:
echo "$mystringwindowsorotherwithemptylastchar" |sed s/.$//

However if there are not then it makes a problem and delete effectively an existing char.

Code:
echo "klklj" |sed s/.$//
klkl

Anyone would have a solution for SH?

Programming :: Warning: Deprecated Conversion From String Constant To Char*

Jul 3, 2010

I've just updated my linux system (Debian) and went to compile some code I'm working on. However it causes some problems, presumable because of GCC up dates. I get many of my subject line errors for example

../../common/Version_Control.cpp: In function int VersionControl():
../../common/Version_Control.cpp:55: warning: deprecated conversion from string constant to char*

So I check up the error and it comes from my error handler code which is a function

extern void SetError(char *string,int error_number)

The net tells me all I need to do is convert char *string to const char *string, however when I do so and recompile I get the following error

Error_Control.cpp: In function �void SetError(const char*, int)�:
Error_Control.cpp:41: error: invalid conversion from �const char*� to �char*�
make: *** [Error_Control.o] Error 1

I think I've done exactly what's recommended ?

Programming :: G++ Warning - Deprecated Conversion From String Constant To 'char*'

Jan 10, 2011

My problem is that the warning keeps apperaing when I run g++ compilation.

Say, I have a system runtime function with header (imaginary)sysruntime.h: void printfunction(char *line);

Then in my .cpp file, I will include the above header #include <sysruntime.h>

Then, I do the below:
Line12: char *linetoprint = "Print this line";
Line13: printfunction(linetoprint);

But, I will get the warning message "Line12: deprecated conversion from string constant to 'char*'". (Even though it compiles)

My question is how should I declare my char* so that I wont get this warning message, and can still run printfunction(char* line) correctly?

Programming :: Point A Char Pointer To A Part Of Another Char Array?

Nov 4, 2010

Programming in C.I have two char arrays.char buf1[1024];char buf2[1024];Aren't buf1 and buf2 also pointers?I read in 1024 bytes into buf1 which contain about 300 bytes of characters with newlines. The data is basically a few English sentences. I'm trying to scan buf1 for newlines and then stop at the 1st newline and copy the rest of the data from that 1st newline into buf2.So I run a for loop to look for that new line.

Code:
for(i=0; i<1024;i++) {

Programming :: C++ Invalid Conversion From Const Char* To Char*

Jul 9, 2010

I am having trouble with the following exception class.

Code:

/**Standard Exception
*
*@description
*@update
*@changes

[code]....

Line 43 points at the snprintf() command.I think the error has to do with the function being virtual and the const after the function definition, however although I have been looking really hard I have not being able to find the reason nor the solution to the problem.

One workaround that I know is moving the block of source withing the virtual function, in the constructor, however having read around (boost library exceptions tutorials) it specifically said that formating of errors messages should not take place withing the construction of objects because we are risking throwing an exceptions and messing up the flow order.

Programming :: Replace 2nd Occurrence Of A String In A File - Sed Or Awk?

Apr 5, 2010

I know how to replace a particular instance (say 3rd one) of a word in a line using sed based on the sed one-liners. However I would like to replace a particular instance of a word in the entire file.

For example, here is a file:

Code:
John
Betty
Jack
Ron
Jack
Paul

So now I would like to replace the second instance of Jack (in red color) with "Rob" (for example). Not quite sure how to do that? I tried couple of things from here but they did not work.

Programming :: Delete Line In File Matching String?

Jan 26, 2010

Quote:Originally Posted by topcatI would like to know how i can write a shell script to delete a line if a particular pattern exists?E.g. I have a text file with multiple lines. Say 1000s. in the following pattern.

username@email.com:149.0.3.4:1
username1@email.com:149.0.3.4:1
username1@email.net:149.0.3.4:1
username1@email.edu:149.0.3.4:1

If the patternusername@email.com exists then the line "username@email.com:149.0.3.4:1 should be deleted from the file.I have a very similar question but I need to delete one line in a file which matches one very precise instance of a string only. Let's assume I have a file composed of thousands of lines and let's call the file chap-secrets. Let's take the following sample entries:

Code:
#USERNAME SERVER PASSWORD IP
pp pptpd blahblah *
