I was playing around xv6 code, I changed the printf content in ls.c command, when I executed make, it showed that xv6 is already up to date
But the changes I did in ls command were indeed showing changes I am not able to get it why
The ls is part of user programs (in vx6-public, I don't know with xv6-riscv), since a simple make only build the kernel, that is normal that ls is not build again.
To build user programs, type make fs.img or make qemu
