Shell Programming and Scripting

hi,
i am a newbie and have to write a rather complicated script. Assume that i have a variable called x and a C source code file say file1.c (these are the inputs of the script) and i need to find the names of all the functions in the C file containing x.Take the following code as an example:

Code:

 1.int main(void);    
 2.void foo(void);    
 3.void bar(void);    
 4.    
 5.int main(void)    
 6.{    
 7.  int x;    
 8.  return 0;    
 9.}   
 10.   
 11.void foo(void)   
 12.{   
 13.  int x;   
 14.}   
 15.   
 16.void bar(void)   
 17.{   
 18.  int x;   
 19.}

so i guess the output should be:


in 5. main(void) x occurs in line 7 as int x;

in 11.foo(void) x occurs in line 13 as int x

and in 16.bar(void) x occurs in line 18 as int x

Something similar to but not exactly as above. To print the name of the functions containing x is crucial.

i can find line number using grep -n and probably use sed -n '/{/,/}/p' file1.c to select blocks of code delimited by { and } but I'm not sure how to refine this further.

any help would be welcome.

thanks,
Sam

Hi,

this will give you the function name containing "int x":

Code:

awk -F'\n' 'BEGIN{RS=""}/int x/{print $1}' file.c

try this it may help you egrep -n '\(|x' list | sort -n
