I am new to curl.
I am using curl to upload a file using shell script.
I have to set the boundary delimiters explicitly and make an HTTP request by passing few fields.
I have couple of questions:
Is it possible to explicitly set boundary delimiters using GET method?
If yes, how?
If not then is it okay to use something like this in a POST method (check the arguments to the --data)
curl --data "--4ebf00fbcf09&AB=MSG&tableView=simple&orient=UP&x-895892-n=1
&x-128754-o=2&x-974573-p=1&client=browser&d-984303-s=create&--4ebf00fbcf09--"
--header "Content-Type: multipart/form-data; boundary=4ebf00fbcf09"

Many Thanks!
Those delimiters are used for multipart formposts, and curl will handle the delimiters automatically for you if you just make sure to use --form instead of --data.
The difference between curl's -d and -F is also explained in the curl book in section aptly titled "-d vs -F".
The manual way
If you truly want to set the boundary yourself, you need to build the entire formpost yourself as RFC1867 dictates.
A shell script to send the two values "name=foo" and "value=42":
#/bin/sh
boundary="------------------------2100d47bb8839948"
# generate the body
echo "$boundary" > post
echo 'Content-Disposition: form-data; name="name"' >> post
echo "" >> post
echo "foo" >> post
echo "$boundary" >> post
echo 'Content-Disposition: form-data; name="value"' >> post
echo "" >> post
echo "42" >> post
## final boundary uses two extra dashes
echo "$boundary--" >> post
curl -H "Content-Type: multipart/form-data; boundary=$boundary" localhost --data-binary @post
