Network Awk script issue
Thanks Ctgsnb,

Hi ! In this script
Code:
sed -e 's/\(RXH[^ ]*\), */\1,%/' FILE1 | tr '%' '\n'

instead of special character % , can we use any expression like "REPLACE" or any other expression to tie it up with tr for replacement of the \1 pattern

Thanks
Jaita

No,

tr handle character per character translation, but you can use § or µ or # or whatever uncommon character that is not supposed to appear in the file you want to parse.

Or give a try to this (dont forget any simple or double quote)

Code:
sed -e 's/\(RXH[^ ]*\), */\1,'"\n"'/' FILE1

Thanks Ctgsnb for your valuable inputs
Still getting familiar with the sed .

having new coding issue ->

Code:
 
FILE1 
#########################
pin (RXEDF) {
input 
output 
};
 
pin (RXEHRR) {
input kdk
output kdkdk 
};
 
pint (RXHERT) {
input jdjd
output kkd
timing () {
   rise_constraint (setup_template_2x2) {
         index_1 ("1.000, 195.000") ;
   }
fall_constraint (setup_template_2x2) {
         index_1 ("1.000, 195.000") ;
   }
     }
 timing () {
       related_pin : "TXHDCLK" ;
       timing_type : hold_rising ;
rise_constraint (hold_template_2x2) {
index_1 ("1.000, 195.000") ;
}
fall_constraint (hold_template_2x2) {
index_1 ("1.000, 195.000") ;
}
}
}
 
pin (RXCER) {
input ioti
output nfnf
};
 
######################

Code:
 
OUTPUT 
####################
pin (RXEDF) {
input 
output 
};
 
pin (RXCER) {
input ioti
output nfnf
};
 
#######################

Need to match regular expression RXH and delete the content

I am using the following sed script

Code:
 
sed '/RXH[^ ]*/,/}/d'

but it is deleting only the limited content as it is matching first } bracket only

Output what I am getting is

Code:
 
Wrong Output 
 
#####################3
 
pin (RXEDF) {
input 
output 
};
 
fall_constraint (setup_template_2x2) {
         index_1 ("1.000, 195.000") ;
   }
     }
 timing () {
       related_pin : "TXHDCLK" ;
       timing_type : hold_rising ;
rise_constraint (hold_template_2x2) {
index_1 ("1.000, 195.000") ;
}
fall_constraint (hold_template_2x2) {
index_1 ("1.000, 195.000") ;
}
 
pin (RXCER) {
input ioti
output nfnf
};
}
}

Please share your valuable inputs with me

Your example is ambiguous with your requirement : the record containing RXEHRR doesn't appear in your output file whereas it doesn't match RXH ...
?
By the way i am a bit confused : is your file correctly formatted (with those } and }; )
Are you sure no ; are missing ?

Hi Ctgsnb

This could be correct file

FILE1
Code:
pin (RXEDF) {
input 
output 
};
 
pin (RXHRR) {
input kdk
output kdkdk 
};
 
pint (RXHERT) {
input jdjd
output kkd
timing () {
   rise_constraint (setup_template_2x2) {
         index_1 ("1.000, 195.000") ;
   }
fall_constraint (setup_template_2x2) {
         index_1 ("1.000, 195.000") ;
   }
     }
 timing () {
       related_pin : "TXHDCLK" ;
       timing_type : hold_rising ;
rise_constraint (hold_template_2x2) {
index_1 ("1.000, 195.000") ;
}
fall_constraint (hold_template_2x2) {
index_1 ("1.000, 195.000") ;
}
}
};
 
pin (RXCER) {
input ioti
output nfnf
};

Output
Code:
pin (RXEDF) {
input 
output 
};

pin (RXCER) {
input ioti
output nfnf
};

with
Code:
sed '/RXH[^ ]*/,/}/d'

but it will take care of the first expression not for the second match because it has to delete till all the 3 } } } brackets

Try this (from line containing RXH to the first empty line found) :

Code:
sed '/RXH/,/^$/d' input

Note : watch out : if "RHX" appears inside a non "RHX" block, the proposed code would not be suitable example :

if a block looks like

Code:
pin (REHRR) {
input kdk
<whatever> RXH <whatever>
output kdkdk 
};

the corresponding unexpected output will be produced:

Code:
pin (REHRR) {
 input kdk

Network awk script issue
Hi Ctgsnb,

Thanks for the Code ^$ matches with the blank lines but in my file
between the pin configurations blank lines are not there
This code will delete everything after the first match
Can u suggest something else to match up with the 3rd } after matching the pattern and deleting the configuration


Thanks
