Unix script for copying files using SCP

[rohithji]

Hi Scripting experts,

I am new to the unix scripting. Please help me out for solving the condition given below

I am trying to develop a script for Copying files which are getting generated in server A to server B using scp. In serverA files are generating as for eg abc1.txt, abc2.txt, abc3.txt.... . I need to append these file contents to a single file in ServerB. Whenever new files are getting generated in the ServerA those file content details need to be appended at the end of the single file in serverB.



Looking forward to hear from you alll



THanking you in anticipation

If you use ssh instead of scp, you could something like this on server A:

cat abc*.txt | ssh serverB 'cat > combined.txt'

The quotes pass the command line, including the redirection operator to serverB. The remote cat command copies stdin since no files were specified.

cat scp.sh
#!/bin/sh

cat abc*.txt &>newabc.txt
#if u r in Server A
#ip of Server B:- 127.0.0.1
scp newabc.txt username@<serverB_IP>:/<path_to_save_file>

This should work. I am assuming that you know the file to be appended to the current file.

------------------------------------------------------------------------------------------
# Let us say you are on local_server and the other server is
# remote_server. Run this script from the local_server.
# temp.txt is a test file. the original file you want to append the
# information is, let us say target.txt

#!/bin/sh

scp new_file.txt@remote_server:<absolute path> temp.txt
cat temp.txt >> target.txt
rm temp.txt

# ">>" is output append redirection operator. this will add new file
# contents at the end of the file.
------------------------------------------------------------------------------------------

Hi Sarma,

In the remote server files are creating automatically and we need to copy all the newer files ( hav to keep the script in background) which wil copy all the newer files from remote location to the local server and append it to the file int he local server.

IS there ny wasys to perform this

You'll need to use the "find" command with one of the newer or time switches.

You might consider "touch"ing a file (to set the time and date) to use as a reference in your script and then using find -cnewer <reference file>

I'll leave you to ponder, rather than give you a solution
