I came across a working ksh script [interactive] today, where I saw the below statement.
printf "Enter the release no. : " >&5
I wonder the use of >&5 when the author could have as well use nothing or say >&1.
Can someone shed some light on this point ?
Thanks in advance

He probably has remapped the file descriptors or does use the file descriptor 5 for something special
e.g. to only temporarily redirect errors to /dev/null
#errors produced here go to stderr
....
#now save stderr to fd 5
exec 5>&2
#redirect to /dev/null
exec 2>/dev/null
...
# do stuff which errors are discarded
......
# restore stderr from fd 5
exec 2>&5
So check more of the script what it does before
