Hi,

Let me try to answer your questions.

#1 What is the command to copy files from 1 Unix machine to another Unix machine, providing that the 2 machines are in the same network.

Ans: SCP should be the way to do it.


#2 How to list dynamic dependencies of executable files or shared objects?

Ans: ldd --> list dynamic dependencies of executable files or shared objects. Check out man page of ldd for more info.

#3 What is one of the disadvantages of using symbolic link?

Ans: I guess it is about softlink , then one disadvantage can be "it can be linked with the file which is not existing actually".

If it is for Hardlink then one disadvantage would be "It can not cross file system".

PS: Plz correct me if am wrong.

1) if you want ot copy file from machine1 to machine 2 and if they are connected then you should use ftp to connect to machine1 to machine2 and fetch the file. Hope this is the answer if wrong please correct.

Hi,

To copy a file from another host use the command:
rcp source_file destination_fileThe source file is given as:
system_name:filenameWhen given as a relative pathname, the filename is interpreted relative to your home directory on the remote host.



To copy a file from your home directory on another host to your current directory on your local host:
rcp goya:notes part1.txtTo copy a file from a subdirectory in your account on a remote host to a subdirectory on your local host:
rcp ubik:gnu/rcs/README tmp/gnu_READMETo copy a file from a remote host on which you have an account under another username:
rcp joe@pollux:News/alt.hypertext tmp/hypertextThanks & RegardsVijay.

How can I start new question and new topic.
