scp shortcut for multiple files

lailai · 03-05-2012, 02:58 PM

Hello guys,

i am pretty new to linux and shell, currently, i am trying to use scp command to transfer files between my computer with a remote server.
every time i type like:

scp user@remote_server.com:/dir/file_1 .
scp user@remote_server.com:/dir/file_2 .
....
scp user@remote_server.com:/dir/file_n .

then i write a script file called 'getr' and put into my /bin directory, the getr looks like
scp user@remote_server.com:$1 .

now i only need to type 'getr /dir/file_1' and 'getr /dir/file_2' to fetch the files from the remote server.
if the files i needed have similar naming rules, i can use the regular expression like 'getr /dir/file_*' to
get the files by only one command, however, for many cases, files i need to fetch have quite different names, like two files with the name 'aaa.txt' and '123455_uyt',
so my question is
is there anyway a way to send the names of wanted files as arguments to some more advanced version of the currently 'getr', so that for several files with quite different names, i can also fetch them by one command?

thank you guys in advance.

Look for these applications in your distro's repository:

dsh
mssh
mussh
pssh
taktuk

One of them should be useful to you.

DSH, for example, can be found here:

Some other ideas as well...

----------

Simple adjustment to the shell script.

Code:

#!/bin/bash

# If anyone other than you is going to be using this,
# you'll want to validate input data. Note that this
# may break if file names have spaces in them.

if [ $# -eq 0 ] ; then

  echo "Usage: $0 file_1 file_2 file_3 file_n"
  exit 1

fi

for I in "$@" ; do

  echo "Downloading $I"
  scp foo@myhost.local:/dir/$I .

done

exit 0

Or look into using rsync(1), if it makes sense for your circumstances. Then you won't have to worry about feeding filenames to a script.
