Very Computer

Hello guys,

I have the following structure :

root : h235 - /tmp/test> ls -l
drwxr-xr-x    2 root     root         1024 dc 14 12:28 a dir
drwxr-xr-x    2 root     root         1024 dc 14 15:04 another one
drwxr-xr-x    2 root     root         1024 dc 14 12:28 the last one

That is, directories with spaces in their names. And I have trouble using
the following for loop :

for i in `ls`; do echo $i; done

Since the default separator is space, i get 6 arguments.

I've tried playing with IFS the following way :

root : h235 - /tmp/test> liste=`ls -F`
root : h235 - /tmp/test> echo $liste
a dir/ another one/ the last one/
root : h235 - /tmp/test> IFS=/
root : h235 - /tmp/test> for i in $liste; do echo $i; done
a dir

another one

the last one
root : h235 - /tmp/test>

Why do I get those empty lines ? And has anyone a solution ?

Thanks

Christian

The output of ls is not meant to be post-processed.

xargs touch << \EOF
a\ \ b\ \
c \ a\ b
EOF
for i in *; do printf '<%s>\n' "$i"; done

Have a look at the FAQ.

  for i in "`ls`"; do echo "$i"; done
or
  ls |while read filename; do echo "$filename"; done

Se question 16 in the FAQ (http://home.comcast.net/~j.p.h/cus-faq.html#P).

    There is no need for ls:

for i in *; do echo $i; done

    If you just want directories:

for i in */; do echo $i; done   ## In a Bourne shell, use */.

But there is a need for quotes:

for i in *; do echo "$i"; done
