Using gawk to add a value separated by a comma

I have a txt file that looks like this.

this-is-name-1
this-is-name-2
...

I am trying to add a ,0 at the end of a certain line using gawk, gawk -i inplace -v n=',0' -v s='this-is-name-1' '$1 == s { $2 = n } 1' file But as you can see there is a space in-between.

this-is-name-1 ,0
this-is-name-2
...

Whats the right gawk syntax so there is no space, so it like this instead

this-is-name-1,0
this-is-name-2
...

Use comma as the output field separator:

gawk -i inplace -v OFS=',' -v n='0' -v s='this-is-name-1' '$1 == s { $2 = n } 1' file
# ..............^^^^^^^^^^.......^ (no comma here)

Change $2 = n to $0 = $0 n. Your current code is adding a 2nd field so awk has to add a separator between the fields.
