Sed strip containing mixed text up to some character

Question

I have a line like this:

14: 32: 38,723 [some text] ERROR - still text ......

I want to delete everything, down to (but not including) the first "[" (so the result will be a line starting with [some text] .....)

My reading

's/^.*\d*\s//' 

is that it should replace everything with a digit followed by a space, but it seems that it applies the replacement everywhere in the line, i.e. being greedy.

I tried:

 's/^.*\s\[//g' 

but he cleans it first "["

How do I change the expression to do what I need? Many thanks

Answer 1

I would apply the following sed command

 s/^[^[]*\[/\[/ 

It replaces everything to the first [ one [ .

 $ echo "14:32:38,723 [some text] ERROR - some more" | sed 's/^[^[]*\[/\[/' [some text] ERROR - some more text 

Answer 2

This might work for you:

 sed 's/[^[]*//' file
