Internal piping with awk

Let say i have input line:

input:

{x:y} abc det uyt llu

how to process it, to get expected output:

output:

{x:y} abc%det%uyt%llu

Question is how to concatanate fields 2-end of line, and in that string change space with % where separator is space

I need fixed first part {x:y} and implementing pipe for fields 2-end of line

Here is another awk

awk '{$1=$1;sub(/%/," ")}1' OFS="%" file


echo '{x:y} abc det uyt llu' | awk '{$1=$1;sub(/%/," ")}1' OFS="%"
{x:y} abc%det%uyt%llu

This change all space to %, using OFS and $1=$1, then change the first % to space.

You can use this awk:

s='{x:y} abc det uyt llu'
awk '{printf "%s%s", $1, OFS; for (i=2; i<=NF; i++) printf "%s%s", $i, (i==NF)?RS:"%"}' <<< "$s"
{x:y} abc%det%uyt%llu

Another awk:

awk '{printf "%s%s", $1, OFS; OFS="%"; $1=""; print substr($0, 2)}' <<< "$s"
{x:y} abc%det%uyt%llu
