Shell Programming and Scripting

Hi ,

how to add the single digit to front of the word and front of the lines in the one file with compare pattern file and get digit. like example

pattern file pattern.txt

Code:

pattern num
bala 2
raja 3
muthu 4

File Name: chennai.dat

Code:

muthu is good boy
raja is bad boy
selvam in super boy
then bala is very good boy

the above two files are there. check the chennai.dat file and compare the pattern from pattern.txt file and place the respective digit to chennai.dat file.

is this what you wanted?

Code:

awk 'FNR==NR && FNR>1{a[$1]=$2} NR>FNR{$1=a[$1] FS $1; print $0}' pattern.txt chennai.dat

output:

Code:

4 muthu is good boy
3 raja is bad boy
 selvam in super boy
 then bala is very good boy

Hi,

Thanks!.
but i want output similar but slightly changes....in the output file need this type..

4muthu is good boy
3raja is bad boy
selvam in super boy
then 2bala is very good boy

Thanks in advance.

Code:

cat pattern.txt  | while read LINE
do
    NAME=`echo $LINE | cut -f1 -d " "`
    NUM=`echo $LINE | cut -f2 -d " "`
    
    cat chennai.dat | sed "s:$NAME:$NUM$NAME:g" > tmp_file.dat
    cat tmp_file.dat > chennai.dat
done

Code:

#!/bin/ksh
while read mLine
do
  while read mName mValue
  do
    mLOut=$(echo ${mLine} | sed "s/${mName}/${mValue}${mName}/g")
  done < Pattern_File
  echo ${mLOut}
done < Main_File

Code:

awk 'FNR==NR && FNR>1{a[$1]=$2} NR>FNR{ for(i=1;i<=NF;i++) if($i in a) $i=a[$i]$i; print $0}' pattern.txt chennai.dat

Thanks but i have few files.and i added one more tab in pattern file.
example: pattern.txt
code pattern num
ax bala 2
ax raja 3
ax muthu 1
ay bala 2
ay raja 3
ay muthu 3
az bala 2
az raja 5
az muthu 6

The report file have a code in the firest line. so first we check the file code compare with pattern file. then will append the digt in the each lines with compare pattern in pattern file to report file.

Help to correct the below script. the script is checking with pattern and place the digit front of the word but i need to change front of the line.


for i in `ls *.R`
do
cat sch.txt | while read LINE
do
CLT=`echo $LINE | cut -f1 -d "|"`
NAME=`echo $LINE | cut -f2 -d "|"`
NUM=`echo $LINE | cut -f3 -d "|"`
echo " $NAME $NUM$NAME "
comp_string=`grep "%s" $i| cut -d ":" -f2 | cut -d "|" -f1`
if [ $CLT = $comp_string ]
then
cat $i | sed "s:$NAME:$NUM$NAME:g" > tmp_file.dat
cat tmp_file.dat > $i
else
echo " Not Matching CLient Code"
fi
done
done
