I want to use sed command to append text at multiple occurrence of string.
For Ex:
Hello world
types="program"
Mario
types="Game"
Hello world
types="program"
Mario
types="Game"
So at first occurrence of Mario i want to append 'firstMario' and at next occurrence 'secondMario', and so on. OutPut:
Hello world
types="program"
firstMario
types="Game"
Hello world
types="program"
secondMario
types="Game"
sed '
/Mario/{
s//first&/
:1
n
s//second&/
b1
}'
Or:
sed '
1 {
x;s/^/first/;x
}
/Mario/ {
G
s/\(Mario.*\)\n\(.*\)/\2\1/
x;s/second/third/;s/first/second/;x
}'
Though to allow more than one Mario per line and generalize to more substitutions, I'd use perl instead:
perl -pe 'BEGIN{@words=qw(first second third)}
s/(?=Mario)/$words[$n++]/ge'
You will have a hard time using "first second third ..." in an automated way, since they are not described anywhere (at least there is no standard tool). I'll give a solution with integers:
n=$( grep -c '^Mario$' file )
for (( i=1 ; i<=$n ; i++ )) ; do
sed -i "1,/^Mario$/s/^Mario$/$i&/" file
done
output:
Hello world
types="program"
1Mario
types="Game"
Hello world
types="program"
2Mario
types="Game"
