I have a line with thousands of lines like this:

"100K";"0.00001";"10";"0.01"]
"101K";"0.0001";"100";"0.1"]
"102K";"1";"1000";"1"]
"102K";"1";"1000";"1"]
"103K";"0.01";"10000";"10"]
"104K";"0.1";"100000";"100"]
"105K";"1";"1000000";"1000"]
"109K";"0.000001";"1";"1"]
"120K";"0.000012";"12";"12"]

I want to replace the first occurrence of ; in a line with :[

Making these lines equal to

"100K":["0.00001";"10";"0.01"]
"101K":["0.0001";"100";"0.1"]
"102K":["1";"1000";"1"]
"102K":["1";"1000";"1"]
"103K":["0.01";"10000";"10"]
"104K":["0.1";"100000";"100"]
"105K":["1";"1000000";"1000"]
"109K":["0.000001";"1";"1"]
"120K":["0.000012";"12";"12"]

how do I do that with sed or other unix command?

You can try with below 2 commands also:

perl -pne "s/;/:[/" filename
sed 's/;/:[/1' filename

Output:

"100K":["0.00001";"10";"0.01"]
"101K":["0.0001";"100";"0.1"]
"102K":["1";"1000";"1"]
