Hi,

I am currently in the process of creating a script that will use cURL to HTTP POST the contents of a file on the server.

I am able to run the command;

Code:

curl -d @/path/to/file/filename.dat "https://posting.server.com/test.aspx"

to post a single file and this works as expected.

The trouble I am experiencing is that I will have a folder that all of the output files which need to be posted will be going into, and the name of each file will change sequentially (number range e.g. 4000001.dat 4000002.dat).

I have created a script which the command;

Code:

curl -d @/path/to/file/*.dat "https://posting.server.com/test.aspx"

But this returns the error;

Code:

Warning: Couldn't read data from file 
Warning: "/path/to/file/*.dat", this makes an 
Warning: empty POST.

I had a look around and cannot see how to perhaps get a list of each file name within the directory, then run my original command for each file name.

e.g.

Files;
4000001.dat
4000002.dat

script should then run commands;

curl -d @/path/to/file/4000001.dat "https://posting.server.com/test.aspx"
curl -d @/path/to/file/4000002.dat "https://posting.server.com/test.aspx"

This is the way i'd imagine it working, but perhaps somebody knows an equivalent to using '*' within the cURL command.

I think I've explained everything, but then again it is a Monday

The @ prevents it from working because the shell takes it literally, and finds no files @/... Also, curl expects the list to be comma-separated.

You could make the list first, then put it in:

Code:

# Save the list of files in $1, $2, ...
# This will overwrite the current values of $1, $2, ...
set -- /path/to/file/*.dat
# Split on , so the list you generate with "$*" will be comma-separated
OLDIFS="$IFS"
IFS=","

curl -d @"$*" "https://posting.server.com/test.aspx"
IFS="$OLDIFS"

Thanks for your reply.

I have taken a look and had a go at this, but unfortunately the files which I need to send must keep their original file name as they are order numbers.

Is it possible to create a script that will run my command for each file in the folder, changing the file name in the command each time?

They do keep their original file names. Take another look at what I did. I'm not replacing files.

Code:

$ touch 01 02 03
$ echo 0*
01 02 03

$ set -- 0*
$ echo "$*"
01 02 03

$ IFS=","
$ echo "$*"
01,02,03

$

I'm just abusing set -- and IFS to produce a list delimited with commas, exactly the way curl wants it.

Hi,

Thanks. I will try it again today. Have not had a chance to look at this properly for a while.
