Subject: fflush(stdout) to print line by line if stdout is not a tty
X-Git-Url: https://git.xinqibao.xyz/slstatus.git/commitdiff_plain/7e29da026b31f02c839b40c4dcf7bd87741a5e4a?ds=inline;hp=7e29da026b31f02c839b40c4dcf7bd87741a5e4a

fflush(stdout) to print line by line if stdout is not a tty

To reproduce the issue:
	$ slstatus -s | tee

then it would print only when the stdout buffer is full, by block
of multiple lines.

fflush() makes sure the line is printed at every loop iteration
