Operating Systems Linux Ubuntu tar not reading if output directed to /dev/null Post 302351379 by thegeek on Tuesday 8th of September 2009 11:01:48 AM

I too did experimentation, but it displayed all the file names.

Before that why you would want to tar and check the integrity, better you can do by reading all the files !!

Use find command with exec, or use dd command with bs & count to read.

NAME
pwd - Return the absolute path of the current working directory SYNOPSIS
pwd _________________________________________________________________ DESCRIPTION
Returns the absolute path name of the current working directory. EXAMPLE
Sometimes it is useful to change to a known directory when running some external command using exec, but it is important to keep the appli- cation usually running in the directory that it was started in (unless the user specifies otherwise) since that minimizes user confusion. The way to do this is to save the current directory while the external command is being run: set tarFile [file normalize somefile.tar] set savedDir [pwd] cd /tmp exec tar -xf $tarFile cd $savedDir SEE ALSO
file(3tcl), cd(3tcl), glob(3tcl), filename(3tcl) KEYWORDS
working directory Tcl pwd(3tcl)
