Hi,

My input file size is huge,but whatever i pasted here ,you can consider as input.

Output of above command is-
Code:
COS_12_TM_4
scan_out[5]
scan_out[9]

I want only - COS_12_TM_4 term

Hello Preeti Chandra,

Let's say following is Input_file.
Code:
cat Input_file
"COS_12_TM_2" [ ......
                                   ......
                                 "scan_out[51]" ] ;
"COS_12_TM_24" [ ......
                                   ......
                                 "scan_out[2]" ] ;
"COS_12_TM_4" [ ......
                                   ......
                                 "scan_out[5]" ] ;
"COS_12_TM_14" [ ......
                                   ......
                                 "scan_out[3]" ] ;

Then my code has give me the expected output mentioned by you as follows only.
Code:
awk '/ \[/{gsub(/\"/,"",$1);VAL=$1;} /scan_out\[5\]/{print VAL}' Input_file
COS_12_TM_4

Let me know if you have any queries or your Input_file looks different.

Thanks,
R. Singh

Yes my input file is different .I try to point the area where scan_out[5] is present in my input file :

Code:
pattern MAIN ( "dft_jtag_sel", "dft_jtag_si", "dtm_global_rstb",  
               "DTM_VTRIM":I, "VDDA_1V8_DTM":I, "VDD_0V9":I, "VSS":I, 
               "scan_out[0]", "scan_out[10]", "scan_out[11]", "scan_out[12]", "scan_out[13]", "scan_out[14]", "scan_out[15]", "scan_out[1]", "scan_out[2]", "scan_out[3]", "scan_out[4]", "scan_out[5]", "scan_out[6]", "scan_out[7]", "scan_out[8]", "scan_out[9]", 
               "DTM_VTRIM":O, "VDDA_1V8_DTM":O, "VDD_0V9":O, "VSS":O )

Code:
"scan_out[15]" : output;      ## pinName = scan_out[15];  tf =  SO  ;  
    "scan_out[4]" : output;      ## pinName = scan_out[4];  tf =  SO  ; 
    "scan_out[5]" : output;      ## pinName = scan_out[5];  tf =  SO  ; 
    "scan_out[6]" : output;      ## pinName = scan_out[6];  tf =  SO  ;


Code:
 "scan_out[1]" := output [ 0ns:X, 50.000000ns:Q, 100.000000ns:X ]; 
    "scan_out[2]" := output [ 0ns:X, 50.000000ns:Q, 100.000000ns:X ]; 
    "scan_out[3]" := output [ 0ns:X, 50.000000ns:Q, 100.000000ns:X ]; 
    "scan_out[4]" := output [ 0ns:X, 50.000000ns:Q, 100.000000ns:X ]; 
    "scan_out[5]" := output [ 0ns:X, 50.000000ns:Q, 100.000000ns:X ]; 
    "scan_out[6]" := output [ 0ns:X, 50.000000ns:Q, 100.000000ns:X ];

Code:
 "scan_out[3]" : output;      ## pinName = scan_out[3];  tf =  SO  ; 
    "scan_out[4]" : output;      ## pinName = scan_out[4];  tf =  SO  ; 
    "scan_out[5]" : output;      ## pinName = scan_out[5];  tf =  SO  ; 
    "scan_out[6]" : output;      ## pinName = scan_out[6];  tf =  SO  ; 
    "scan_out[7]" : output;      ## pinName = scan_out[7];  tf =  SO  ;

Code:
Last same which i posted earlier as input file.

Code:

         "dummy_COS_12_1_TM_4",
         "dummy_COS_12_2_TM_4",

         "dummy_COS_12_35_TM_4",
         "dummy_COS_12_36_TM_4",
         "dummy_COS_12_37_TM_4",
         "dummy_COS_12_38_TM_4",
         "dummy_COS_12_39_TM_4",
         "dummy_COS_12_40_TM_4",
         "scan_out[5]" ];

Lastly I want output from the last part of the file.

Can you explain me your command?
I will try at my end.

Hello Preethi Chandra,

Your Input_file is not clear, please mention it more clearly. I have considered a Input_file which I posted in my previous post too, following is explanation of command.
Code:
awk '/ \[/                    #### Searching for a line which has " [" in it, so here I am using \[ to tell awk that take [ char to be searched not it's special meaning to be searched.
{gsub(/\"/,"",$1);        #### Now if that string found in a line then removing "(which they are there in the very first field) from first field.
VAL=$1;}                   #### creating a variable named VAL and storing $1's(fist field)'s value in it.
/scan_out\[5\]/           #### Now I am searching for string scan_out[5], here again I have escaped the characters [ and ] so that they should be taken as it is by awk.
{print VAL}                #### So if above string found in any line of Input_file then print the value of variable VAL which is nothing but your expected output.
' Input_file                 #### Mentioning the Input_file here too.

Also do not run above command it is only for explaining purposes, you should run my previous post command only. Let us know clearly what is your sample Input_file on single code tags then all the conditions by which you want to achieve the expected output too.

Thanks,
R. Singh

Thank you very much for the explanation...

I am not getting the following command purpose-
Code:
{gsub(/\"/,"",$1);        #### Now if that string found in a line then removing "(which they are there in the very first field) from first field.

Hello Preeti,

You could use THANKS button at left post corner for any useful post to anyone. So here is why I have used that command:
In your Input_file eg--> "COS_12_TM_2" first field is having chars " so you don't want them into your output so I had removed it, by using awk's global substitution keyword.

Thanks,
R. Singh
