I want to remove , from a string in jq. Take the following example, how to remove , when outputting 1,2?

Answer 1

You can use sub.

Filter

.x | sub(","; " ")

Input

{"x":"1,2"}

Output

1 2

Answer 2

You didn't make clear what output you wanted. A literal reading suggests you want 12, but I find it more likely that you want each of the comma-separated items to be output on separate lines. The following achieves this:

jq -r '.x | split( "," )[]'

For the provided input, this outputs

1

But if 12 is indeed what's desired, adding a join will do the trick.

jq -r '.x | split( "," ) | join( "" )'

12
