How to redirect output of a command to a variable during ftp mode?
Hi,

How can I redirect the output of a following command to a variable.

Code:
ftp myservername
ftp> user
(username) guptaji
331 Password required for guptaji.
Password:
ftp> size /home/salil/abc.dat
ftp> a='size /home/salil/abc.dat'
?Invalid command

I want to redirect value of size to some variable and during ftp it is showing invalid command error
Actually I need to compare this size(of remote file) with available disk space on my local machine.

So also tell me how can I convert the available disk space on my local machine in bytes and then compare it with remote file size.

Thanks a lot for your time.
Salil

ftpd_selinux

ftpd_selinux(8) 					 ftpd SELinux policy documentation					   ftpd_selinux(8)

NAME

       ftpd_selinux - Security-Enhanced Linux policy for ftp daemons.

DESCRIPTION

       Security-Enhanced Linux provides security for ftp daemons via flexible mandatory access control.

FILE_CONTEXTS
       SELinux requires files to have a file type. File types may be specified with semanage and are restored with restorecon.	Policy governs the
       access that daemons have to files.

       Allow ftp servers to read the /var/ftp directory by adding the public_content_t file type to the directory and by restoring the file type.

       semanage fcontext -a -t public_content_t "/var/ftp(/.*)?"

       restorecon -F -R -v /var/ftp

       Allow ftp servers to read and write /var/tmp/incoming by adding the public_content_rw_t type to the directory and  by  restoring  the  file
       type.  This also requires the allow_ftpd_anon_write boolean to be set.

       semanage fcontext -a -t public_content_rw_t "/var/ftp/incoming(/.*)?"

       restorecon -F -R -v /var/ftp/incoming

BOOLEANS

       SELinux policy is based on least privilege required and may also be customizable by setting a boolean with setsebool.

       Allow ftp servers to read and write files with the public_content_rw_t file type.

       setsebool -P allow_ftpd_anon_write on

       Allow ftp servers to read or write files in the user home directories.

       setsebool -P ftp_home_dir on

       Allow ftp servers to read or write all files on the system.

       setsebool -P allow_ftpd_full_access on

       Allow ftp servers to use cifs for public file transfer services.

       setsebool -P allow_ftpd_use_cifs on

       Allow ftp servers to use nfs for public file transfer services.

       setsebool -P allow_ftpd_use_nfs on

       system-config-selinux is a GUI tool available to customize SELinux policy settings.
