creating a directory remotely implicitly

t-rex has asked for the wisdom of the Perl Monks concerning the following question:

Hi guys , I am transferring a file on remote host using openssh package using function scp_put(), the place where i intend to transfer this file has to be under certain directory which also should be created by us based on a uid/date. but it throws me error that transfer failed coz directory is not present on remote host. so how do i create this directory remotely.


for example :
$sourcedir = "/tmp/xyz/test.tar";
$remotedir = "/tmp/some-dir/myfolder_uid_date/";
ssh->scp_put ( $sourcedir, $remotedir); or die "scp failed";
[download]

the output should be i should be able to transfer test.tar in the remote dir path, but i need to create this remote dir path on the fly or from host itself. how can i achieve this ? right now i get error no such file or directory /tmp/some-dir/myfolder_uid_date/

I guess you're using the OpenSSH package. If so, it allows you to run remote commands using the `->system` method. So, to create a remote directory before copying, you could run: `$ssh->system(qq{mkdir "$remote_dir"});` [download]	[reply] [d/l] [select]

i get the error cannot create directory still aftre using the qq command, is it that we can't create a directory within directory from one single command ? for example : /tmp/some-dir/some-dir2/xyz_uid_date/ now i have to create some-dir/some-dir2/xyz_uid_date/ in one command , how can that be done ?

how can that be done ? According to the mkdir(1) manual page, using the option `-p` creates the parent directories of the target. Thus, `$ssh->system(qq{mkdir -p "$remote_dir"});` will do the trick. perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'	[reply] [d/l] [select]

Another option, besides running `mkdir -p $targetdir`, is to use SFTP: `my $sftp = $ssh->sftp; $sftp->put($sourcefile, $remotefile);` [download]	[reply] [d/l] [select]

I am not familiar with this package, but I know that with `scp`, using the recursive (-r) option you may place a hierarchy of directories and files onto the remote machine. Similarly, you can use `rsync`. With that in mind, you could mirror the structure you want locally, then do a recursive `scp` or an `rsync` (using a Perl module hopefully) to achieve the effect you desire.	[reply] [d/l] [select]
