Shell Programming and Scripting

Man Page for scp (All Section 0) - The UNIX and Linux Forums
Sorry about the width, but this web site goes beserk with some symbols, in code space, where it is supposed to butt out:

Code:

scp user1@host1:relative_or_full_path_of_source_files_or_dirs  [ user2@host2:relative_or_full_path_of_source_files_or_dirs . . . ] user_t@host_t:relative_or_full_path_of_target files_or_dirs

Much like cp, mv, rcp:

Thanks for the code. I followed the same and made this code

Code:

#!/bin/bash
dir=/usr/sap/nxa/comm/interface/fico/
scp fico@share.dteenergy.com:'get_file*'$dir
for I in $dir/get_file.*
   mv $I $dir/get_file_123${I#get_file}.csv
done
uuencode $dir/get_file_123.csv $dir/get_file_123.csv.mail | mail -s "get_file_123.csv" venkat@yahoo.com; rama@yahoo.com; 
rm $dir/get_file*

Looks like the space before scp target got lost, but that's the idea.

Why "ftp bla bla bla mget bla bla bla" when you can scp on one line?

Using ksh on systems like Solaris with /dev/fd/[0-9]* or bash <(...) or >(...), or on systems like Solaris with /dev/fd/[0-9]* using /dev/stdin or /dev/stdout, you can even scp from or to a named pipe and pipe the data to/from your process in real time.

"ftp bla bla bla mget bla bla bla" this is the one you asking with the previous code?

space before scp target got lost - i did not get you..

it is a script to automize the file transfer & send mail process.

Using ksh on systems like Solaris with /dev/fd/[0-9]* or bash <(...) or >(...), or on systems like Solaris with /dev/fd/[0-9]* using /dev/stdin or /dev/stdout, you can even scp from or to a named pipe and pipe the data to/from your process in real time.

yes we have many options to minimize the process.

Code:

scp source target 
scp fico@share.dteenergy.com:'get_file*'$dir

maybe should be (without hypertexting and underlining from web site:

Code:

scp fico@share.dteenergy.com:'get_file*'  $dir

Also, '...' are overkill as the host: stifles local globbing. I like to " around $var, though, in case they develop white space or emptiness:

Code:

scp fico@share.dteenergy.com:get_file* "$dir"

Keep it simple, and you can make more complex things work!



I hate:and so I love all sorts of pipes.

yes the single ' can be overkill but shouldn't hurt. The " around $DIR should be fine(might be better if a path contains blanks anyway).

also, in stead of a password, you suggested me to use a private/public key pair (SSH - keygen). i am stucked here. i read the man page and understand but i am blank face(?) because not able to understanding how to use these expressions in my script? if possible, plz suggest me how could i do it? Thanks

You can find articles all over, including here, on getting ssh started. Get ssh2 if you can. Some sort of ssh keygen will give you nice big tough keys. Do not put a password in the keys, or you are back in the same kettle with better security. Make sure the permissions are right on the .ssh/.ssh2 dir, wherever it is. Here, it is not in $HOME because it is a mounted NFS disk. Get the local host name to work for "ssh host_name pwd". Once you get that ssh to work paswordless, if you copy the .ssh/.ssh2 dir to a remote host using scp -rp with a password once interactively, you will be passwordless to that host, give or take an initial save of host keys.
