ksh(!93) for loop with wildcard and empty directory
I'm sure this is by design, but using something like
Code:
for f in dir/*
do echo $f
done
produces unexpected (to me) results if run against an empty directory. I'd have expected it to not execute the loop, but it actually calls it with f set to 'dir/*'.
Now I know that I'm trying to protect against it:
Code:
for f in dir/*
do [ -f $f ] && #do something
I've got paranoid though, that if a file is created between the for statement and the file test, the test will succeed and the loop will execute with f = 'dir/*'. This is likely to cause interesting results
The only solution I can think of is checking the value of f:

if ; then

But surely there is a more easy-to-read and elegant way. Isn't there? (6 Replies)
