Hello,

I need your help.
I want to create a condition on my file. The goal is to recover only the beginning and the end of a block of data.

For example :

code | start | end | client
01m 2:03 4:10 Jackson
01m 2:10 4:02 Carla
01m 1:10 3:02 Clara
01m 1:23 3:40 Ed
02i 2:02 2:10 Layla

I want him to send me back: (because the code has changed)

code | start | end | client
01m 2:03 4:10 Jackson
01m 1:23 3:40 Ed
02i 2:02 2:10 Layla

If you have any tips to help me, I'd love to hear from you.
