Shell problem

Catherine_3 — Tue, 02 Apr 2002 18:59:04 GMT

I met a problem.
I have a file named ss
ss:
consulting
Global Exotica - DEVADM
Global Exotica - DEVSTD
NSD

My question:
for dirname in `cat ss`
do
echo "$dirname"
mkdir "$dirname"
done

I cannot get the dirname "Global Exotica - DEVADM" and Global Exotica - DEVSTD" because of the space

Hope I can get feedback
very appreciated advance

I can suggest getting rid of the spaces in file "ss". For example ..

# sed 's/ //g' ss > ss.new

The "ss.new" file would then looked like ..

consulting
GlobalExotica-DEVADM
GlobalExotica-DEVSTD
NSD

Now run it through the for loop.

You can do spaces, but it's not a good idea because of parsing rules.

# mkdir "this is stupid"
# ls -l | grep this
drwxrwxrwx 2 root sys 96 Apr 2 14:05 this is stupid
#

put filename in QUOTES

Hi,

You can change all space by a _.

cat ss | sed s/" "/_/g >! ss.new

change the FS (field separator) variable to just use linefeeds:

OLD_FS=$FS
FS=`echo "\n"`
for...
...
done
FS=$OLD_FS

You can do this

for dirname in `cat ss`
do
echo "$dirname"
mkdir "${dirname}"
done

Use read instead of for. Since you have multiple variables on an input line, read will place the entire line in dirname.

while read dirname
do
echo $dirname
mkdir "$dirname"
done

Hi
Try this
ss:
"consulting "
"Global Exotica - DEVADM "
"Global Exotica - DEVSTD "
"NSD "

Add "" in file ss and then

#cat ss |xargs mkdir

Thanks
Prashant.

Hi Catherine,

Did you try the "while read dirname" loop? For each line of ss, $dirname will contain the entire line, spaces and all and it will create the directories with names like "Global Exotica - DEVADM".
