package require tar

doomrak has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I have a tcl script calling a lot of perl scripts.

In the beginning of one of the scripts is the command:

#!/bin/sh 
#\
exec wish "$0" "$@"
package require tar
[download]

The use is later on down the script in the following lines:

   cd [file dirname $source]
   tar::create /tmp/directoryCopy.[pid].tar [file tail $source]
   cd $pwd
   cd $dest
   tar::untar /tmp/directoryCopy.[pid].tar
   file delete -force /tmp/directoryCopy.[pid].tar 
   cd $pwd
[download]

As soon as I run the script,I get the error message:

Error in startup script: can't find package tar
    while executing
"package require tar"
    (file "package.tcl" line 6)
[download]

could you pls help me debug the reason for the error?

thanks karuna

There is no `tar` module on cpan, so you are probably missing a custom module of your shop/organization/whatever. where did you get the script from? holli You can lead your users to water, but alas, you cannot drown them.	[reply] [d/l]

Hi! What operating system do you use? It looks like your shell script can't call tar to unpack the tar file in /tmp . Tcl itself can process tar files using the tcllib package. If you wanted to rewrite the shell script using Perl, I would install Archive::Tar	[reply]
