具有2个变量循环的Bash脚本

Question

I'm having some hard time to work this one out. I need to feed GITLAP API with issues that are created based on a file that i have. Normally the output of the file is the following:

Microsoft xxx xxxxx - Remote Code Execution xxxxxx- April 2018 xxxxx Updates Red Hat Enterprise xxxx - java-1.8.0-xxxxx Multiple xxxxxxx- RHSA-xxxxxx

So far so good, I already deal with this the following way:

while read in; do 
    curl --request POST --header "PRIVATE-TOKEN: xxxxxxxxxxxxx" https://gitlab.com/api/v3/projects/xxxxxx/issues?title="$in"; 
done < ~/input_file

The problem is now that i need to add a second variable to this because i need to introduce a description on each issue and now my input file change for the following:

Microsoft Malware Protection - Remote Code Execution Vulnerability - April 2018 Security Updates 40697
Red Hat Enterprise Linux 6 - java-1.8.0-openjdk Multiple Vulnerabilities - RHSA-2018:1188 40861

I would like to construct something like this:

while read in; 
    curl --request POST --header "PRIVATE-TOKEN: xxxxxxxxxxx" "https://gitlab.com/api/v4/projects/xxxxx/issues?title=$in&description=https://myspecialink.com/portal/notifications/show/$id"; 
done < ~/input_file

for example:

• $in : must be everything except the bold number that i signalize above.
• $id : must be only the numbers in bold above.

Can someone help me on point me the best way of achieve this?

Use bash parameter expansion operators to split the input.

while read in; do
    id=${in##* }  # Remove everything up to last space
    in=${in% *}   # Remove everything from last space
    curl --request POST --header "PRIVATE-TOKEN: xxxxxxxxxxx" "https://gitlab.com/api/v4/projects/xxxxx/issues?title=$in&description=https://myspecialink.com/portal/notifications/show/$id"; 
done
