To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)

Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Use gawk, nawk or /usr/xpg4/bin/awk on Solaris:

Code:
awk '/^public function/, /END public function/ { 
  /^public function/ && fn = $0
  if ($0 ~ sc) print fn
  }' sc='call Global Function1' infile

How to find function name based on word search

Just I want to display names of all the functions which are called "call Global Function1()".

so based on above file ( file1.txt) output should be

Code:
 
public function calculate1()
public function calculate2()
public function calculate3()

these functions are used to call
Code:
call Global Function1()

So please give me any idea how to proceed. I have basic knowlege of shell scripting.

hi radoulov,

Ur code is giving syntax errors ...i couldnt rectify....
Code:
 
awk '/^public function/, /END public function/ { 
  /^public function/ && fn = $0
  if ($0 ~ sc) print fn
  }' sc='call Global Function1' infile

[/CODE]

Im getting following errors :

awk: syntax error near line 2
awk: illegal statement near line 2
awk: illegal statement near line 3

If possible please tell me how to fix above syntax errors for "awk" code

But i tried like this. Its working.....

Code:
 
cat infile|while read line
do
        echo $line |tr -d " "|grep "publicfunction"|grep -v END
        if [  $? -eq 0 ]
        then
                echo $line |read fname
        else
                echo $line |tr -d " "|grep "callGlobalFunction1"  
                if [  $? -eq 0 ]
                then
                        echo "--------" $fname
                fi
        fi
        echo $line |tr -d " "|grep "ENDpublicfunction"
        if [  $? -eq 0 ]
        then
