UNIX for Dummies Questions & Answers

Hi,

I'm new to Linux. I would like to know how to scp a group of files. I have the below command, but it asks for remote password while sending each file. Is there a way to send all files (identified by - $ ls | grep '.*hrs0314a.*' | xargs -I {} grep -l '.*35663.*' {}) in one go?

$ ls | grep '.*hrs0314a.*' | xargs -I {} grep -l '.*35663.*' {} | xargs -I {} scp {} user1@example.com:/home/user1/Workplace

Thanks in advance for any suggestions.

scp -vv* .xlsx username@(ip address of the machine where you are sending)
this is for the files with xlsc extention ,use same with .txt extention.

if you have 5 files for example use scp file1 file2 file3 with same

Hi,
first, think about using keypair-based authentication to get rid of the password prompt.

Second, you can provide filenames with the '*' wildcard to scp in order to copy multiple files (warning! you must escape the wildcard character if using it on the remote file specification!).

Hi

I'm afraid I didn't explain enough what I actually want to achieve.

Let's say there are 50 files in the directory. First I'm finding out all files that has the string 'hrs0314a' in their file names. Assume there are 30 such files. In this list of 30 files, I'm looking for those files containing the string '35663'. Assume there are 20 such files.

I have the below command to get the final list of 20 files.

$ ls | grep '.*hrs0314a.*' | xargs -I {} grep -l '.*35663.*' {}

Now I want to scp these 20 files to a remote server. I tried using xargs, but it's prompting for remote password for every single file. (20 times)

$ ls | grep '.*hrs0314a.*' | xargs -I {} grep -l '.*35663.*' {} | xargs -I {} scp {} user1@example.com:/home/user1/Workplace

I'm wondering if there is a way to send these 20 files in one go by entering remote password only once.

If the position of 'hrs0314a' and '35663' with respect to each other in the filename is always the same you can use wildcards in the filename, i.e. (assuming that 'hrs0314a' comes before '35663'):

Code:

$ scp *hrs0314a*35663* user1@example.com:/home/user1/Workplace

anyway, as wildcards expansion is made by the shell, I suspect (cannot test myself at the moment) that scp opens a new connection for every filename expanded, so goin' with key-based authentication may resolve the issue.

Thanks. May be key-based authentication is the way to go.
