Full Discussion: check the directory exist
Top Forums Shell Programming and Scripting check the directory exist Post 77097 by mbb on Monday 4th of July 2005 09:59:17 AM

FYI ust:

if [ -d $dir ]
then
...
fi

is actually using the 'test' command. To find out what you can do with the test command then type: 'man test'

You may also write the above as:

if test -d $dir
then
...
fi

or even use the test command on the comand line thus:

>test -d $dir
>echo $?

Also I would recommend shell variables to be quoted in this context:

if [ -d "$dir" ] ...

to avoid any command line errors with the test command!

i.e. if $dir were emtpy and you did if [ -d $dir ], then you would really be running: 'test -d' and the test command would complain.

Hope this helps.
