script to tell whether there exists directory or not
Hi,

I am writing a script as follows:

Code:
#!/bin/sh
set -x
for i in `cat a`; do
#sleep 3
print $i >> server.txt
sleep 5
if test -d `vtask  $i "' ls -lrt /opt/log/ '" ` ;
then
print $i >> 12.5.txt
else
print $i >> 12.0.txt
fi
done

where the vtask is a command line execution script
in my 'a' file I have some servers

I want to check if the log directory exists in the servers if it exists then it should update in the 12.5.txt else if the log directory does not exists if should update in the 12.0.txt directory.

Any corrections in my code please help

Thanks
Dinesh

bzexe

BZEXE(1)						      General Commands Manual							  BZEXE(1)

NAME

       bzexe - compress executable files in place

SYNOPSIS

       bzexe [ name ...  ]

DESCRIPTION

       The  bzexe  utility  allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
       penalty in performance).  For example if you execute ``bzexe /bin/cat'' it will create the following two files:
	   -r-xr-xr-x  1 root  bin   9644 Feb 11 11:16 /bin/cat
	   -r-xr-xr-x  1 bin   bin  24576 Nov 23 13:21 /bin/cat~
       /bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file.  You can remove /bin/cat~ once  you  are	sure  that
       /bin/cat works properly.

       This utility is most useful on systems with very small disks.

OPTIONS

       -d     Decompress the given executables instead of compressing them.

SEE ALSO

       bzip2(1), znew(1), zmore(1), zcmp(1), zforce(1)

CAVEATS

       The  compressed	executable  is a shell script. This may create some security holes. In particular, the compressed executable relies on the
       PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep).

BUGS

       bzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually  in  some  cases,
       using chmod or chown.
