avoid error on terminal window!
Hi Guys,
I am using simple ls command to find out whether the dir exist there or not. If dir found than remove. But the problem is I don't want the error shown on the terminal window that "dir not found" on the terminal window everytime i execute it. The code I am using is:
Code:
 
set x = `/bin/ls -1d temp | wc -l`
if ($x > 0) then
/bin/rm -rf temp
endif
 
Option 2:
I also tried
set x = `/bin/ls -1d temp | wc -l` >& /dev/null

Option 2 doesn't seem to be working at all, since still it comes up with the error message saying ls: cannot access temp: No such file or directory if temp doesn't exist although if I do echo $x the value is 0, so the logic seems to be working. How can I avoid the error message on the terminal window without changing my logic?

Thanks in advance

mvdir

mvdir(1M)																 mvdir(1M)

NAME

       mvdir - move a directory

SYNOPSIS

       dir newdir

DESCRIPTION

       moves one directory tree into another existing directory (within the same file system), or renames a directory without moving it.

       dir must be an existing directory.

       If newdir does not exist but the directory that would contain it does, dir is moved and/or renamed to newdir.  Otherwise, newdir must be an
       existing directory not already containing an entry with the same name as the last pathname component of dir.  In this case,  dir  is  moved
       and becomes a subdirectory of newdir.  The last pathname component of dir is used as the name for the moved directory.

       refuses	to  move  dir  if  the	path specified by newdir would be a descendent directory of the path specified by dir.	Such cases are not
       allowed because cyclic sub-trees would be created as in the case, for example, of which is prohibited.

       does not allow directory to be moved.
