You can store the output of a command like this: var=`command`, so this should work fine for you: json=`curl -H "Content-Type: application/json" -X POST -d '{"hash":"$restearterHash"}' {$host}ApiController/jsonRestarter/ | python -m json.tool`

  • `var=$(somecommand)` is the modern syntax (present in the 1991 POSIX sh standard, so present in any standard-compliant shell written or updated in more than 25 years). `$()` nests better than backticks, and backslash literals contained therein have less surprising behavior. – Charles Duffy Sep 30 '17 at 13:57

You could use command substitution:

VAR=$(curl -H "Content-Type: application/json" -X POST -d '{"hash":"$restearterHash"}' {$host}ApiController/jsonRestarter/ | python -m json.tool)
echo "${VAR}"
