You want to repalce 0001 in the begging or anywhere. Please be specific

you can use sed or tr command to achive this. Otherwise you will write a perl program for the same

Hi,

Try this...

Code:
#!/bin/sh

file_to_search=file.txt
original_file=$file_to_search

cp $original_file newfile
for da_b in $(cat /test/input.txt)
do
sed "s/Event: \"${da_b}\"/Event: \"un_${da_b}\"/g" $file_to_search > test_$da_b
rm $file_to_search
file_to_search=test_$da_b
done

cat $file_to_search
rm $file_to_search
cp newfile $original_file
rm newfile

Is not safe to edit-in-place, use a temporary file for output and move the temporary file over old file.
