UNIX for Dummies Questions & Answers

Hi i have to insert the below line into a specific line number of another file
export MBR_CNT_PRCP_TYPE_CODES_DEL="'01','02','04','05','49','55','UNK'"
I have passed the above line to a variable say ins_line. I have used below command to perform the insert
awk 'NR==3{print "'"${ins_line}"'"}1' MBR_CNT_PARM_DV_TEMP.parm > $Parm_file_name

But i am getting the following error

Syntax Error The source line is 1.
The error context is
NR==xx{print "export >>> MBR_CNT_PRCP_TYPE_CODES_DEL="' <<<
awk: 0602-502 The statement cannot be correctly parsed. The source line is 1

Kindly give suggestions so that i could perform the insert of the line irrespective of the contents (mean- even it has single/double quotes.

Thanks in advance

Yeah.... that's not going to be easy.

Try this?

Code:

awk -v ins_line="$MBR_CNT_PRCP_TYPE_CODES_DEL" 'NR==3{print ins_line }1' MBR_CNT_PARM_DV_TEMP.parm > $Parm_file_name

Somehow I dont think that will do what you want. You can do it with shell scripting:

Code:

let lineno=1
cat "MBR_CNT_PARM_DV_TEMP.parm" | 
while read line ; do 
   if [ 3 == "$lineno" ]; then
        echo "export  MBR_CNT_PRCP_TYPE_CODES_DEL=\"$MBR_CNT_PRCP_TYPE_CODES_DEL\""
   fi
   let lineno=lineno+1
   echo "$line"
done >$Parm_file_name
