Hi,

I want to know how can we do pull up a string up to a position.

For example

I have a variable /disk5/oracle/admin/arch/arch_123.dbf

I require the output to be stored in a variable
as /disk5/oracle/admin/arch/

Can anyone help out how to solve this

Thanks in advance

look at the "dirname" command.

 

[usfrog]

"dirname" command will give you the path information of a file (command complementary to "basename&quot.
Hope this will help

It's not a actual file name, it's only a dummy path and it gives an error!!

Thanks for your help anyway

 

[bjverzal]

echo $variable|dirname

I am getting a blank output.

$export dest=/disk5/oracle/admin/arch/arch_123.dbf
$echo $dest|dirname
$
$

Whereas I require the output to be
/disk1/oracle/admin/arch/

Thanks a lot for your help

Here is what I've found...

$ dest="/disk5/oracle/admin/arch/arch_123.dbf"
$ echo $dest
/disk5/oracle/admin/arch/arch_123.dbf
$ echo $dest|dirname
.
$ dirname $dest
/disk5/oracle/admin/arch

So, the latter should work.

 

[SridharSrini]

$echo `dirname $dest`

It worked!!

Thanks a lot for your help.
