-----------------

error message:
# rm -r /U03
rm: /U03 non-existent

Shalom,

Check the logs.

Either its really not there or you are not giving the correct path.

rm -rf /U03

If you created a logical volume using lvcreate then it will have a path set in the volume group configuration directory.

Lets say I created lvol1 in vg01

The entry for this logical volume is in /dev/vg01 lvol1 and rlvol2

Hi:

If the directory isn't truly non-existent, then its name probably contains unprintable characters. You can do:

# ls -bl /U03

...to see the unprintable characters as octal values

You could do (carefully):

# rm -r /U03*

You MUST BE CAREFULL with this as there are a number of invalid chars in your dir name.

ls -l /U*033*
if this returns only your messed up dir
then
rmdir /U*033*
or
find / -name "U*033*" -exec ls -ld {} \;
if this returns only the messed up dir
then
find / -name "U*033*" -exec rmdir {} \;
(I purposefully did not use rm -r)

Hi,

try the rmdir -i option

# rmdir -i U*

and answer yes to one above U\033[2~03

Hi:

Yes, if you do:

# rm /U*

...you are asking the shell to expand "U" into every file and/or directory that begins with that letter and then run the remove command on those objects.

I *URGE* you to add the interactive ('-i') option to commands like this *or* to first examine what is going to happpen by doing:

# echo /U*

# rm -i /U*

Hi (again):

I'm sorry, my last answer was wrong for the way your question was worded.

You need to use 'rmdir' to remove a directory. Further, that only removes an *empty* directory. You *can* use 'rm' to remove a directory and all its contents, however, if you add the '-r' flag to descend into the directory (r)ecursively.

Hence, if you do:

# rm -r /U*

...you would remove *all* directories and files that begin with the letter "U". You would be much better advised to first check what's going to happen by first doing:

# echo /U*

and/or adding the '-i' flag:

# rm -r -i /U*

...unless you are very sure of what you are asking.

Regards!

Hi

I think best way is

rm -r "U\033[2~03" this will delete this directory only.

>Sanjeev: I think best way is

You, Tim and JRF are confusing escape mechanisms.

This isn't going to work in a real shell. Those shells know nothing about \033. Though your suggestion leads to this:
cd "U^V(ESC)[2~03"
(That's control-V followed by Esc or ^[ below.)

$ mkdir "U^[[2~03"
$ ll -b
drwxrwxr-x U\033[2~03/
$ cd "U^[[2~03"
$ pwd
/var/tmp/U2~03
$ pwd | vis
/var/tmp/U\e[2~03

Cleanup and files and subdirectories.
$ cd ..
$ rmdir -i "$OLDPWD"
(Checking the name carefully.)

And your suggestion also leads to:
$ cd $(echo "U\033[2~03")

Or if there are embedded blanks:
$ cd "$(echo 'U\033[2~03')"
