Ahah! I bet you are right. I have aliased ls as:
alias ls='ls --color --group-directories-first'
which is the way I like ls to work. Let's do a test:
[01:19 nirvana:/home/david] # mv /etc/bash.bashrc.local /etc/bash.bashrc.local.sav
[01:19 nirvana:/home/david] # x
exit
01:19 nirvana:~> su
[01:20 nirvana:/home/backup/rpms/compiz_X11.0] # for i in $(ls); do echo "dir:
$i"; done
dir: i586
dir: noarch
dir: repodata
dir: repoview
dir: src
dir: x86_64
now dropping back to my user shell where the alias is still applied:
01:21 nirvana:/home/backup/rpms/compiz_X11.0> for i in $(ls); do echo "dir: $i";
done
dir: i586
dir: noarch
dir: repodata
dir: repoview
dir: src
dir: x86_64
Double Huh??? Now it works?? I haven't altered the environment for this shell
yet?? Let's use my original command line:
01:22 nirvana:/home/backup/rpms/compiz_X11.0> for i in $(ls); do ls ${i}; done
ls: cannot access i586: No such file or directory
ls: cannot access noarch: No such file or directory
ls: cannot access repodata: No such file or directory
ls: cannot access repoview: No such file or directory
ls: cannot access src: No such file or directory
ls: cannot access x86_64: No such file or directory
Ah hah! I knew I was screwing myself, I just didn't know how. Let's find out:
01:23 nirvana:/home/backup/rpms/compiz_X11.0> for i in $(ls); do echo "'$i'"; done
'i586'
'noarch'
'repodata'
'repoview'
'src'
'x86_64'
01:24 nirvana:/home/backup/rpms/compiz_X11.0> for i in $(ls); do echo "'ls
${i}'"; done
'ls i586'
'ls noarch'
'ls repodata'
'ls repoview'
'ls src'
'ls x86_64'
01:25 nirvana:/home/backup/rpms/compiz_X11.0> for i in $(ls); do echo "'ls
${i}'"; ls $i; done
'ls i586'
ls: cannot access i586: No such file or directory
'ls noarch'
ls: cannot access noarch: No such file or directory
'ls repodata'
ls: cannot access repodata: No such file or directory
'ls repoview'
ls: cannot access repoview: No such file or directory
'ls src'
ls: cannot access src: No such file or directory
'ls x86_64'
ls: cannot access x86_64: No such file or directory
... I give up :-( ...
