Dear Maintainer,
if the value of $PATH ends in a colon (':'), skripts in the current directory
are executed without requiring the './' path-prefix.
The current directory is the last one taken into account though.
Here is, how I triggerd the bug:
----8<--- SNIP ----8<----
sh# /bin/bash
sh# cd /tmp
sh# echo '#!/usr/bin/env perl' > test.pl
sh# echo 'print "In PATH...\n"' >> test.pl
sh# chmod u+x test.pl
# Now set $PATH to a sensible value:
sh# export PATH=~/bin:/bin:/usr/bin:/usr/local/bin
sh# test.pl
bash: test.pl: Command not found.
# Now set $PATH to the same value, colon appended:
sh# export PATH=~/bin:/bin:/usr/bin:/usr/local/bin:
sh# test.pl
In PATH...
---->8--- SNIP ---->8----
I'd expected the last line of output to be:
bash: test.pl: Command not found.
