Expanding Bash shell variable in Curl in Cmder

2019-08-23 02:31发布

问题:

On a Window 7 machine in Cmder emulator in Git bash window, I'm trying to capture the ISO-formatted current date:

$ date +%s
1513354497

to be sent inside the body of curl POST request:

$curl.sh -X POST -H "Content-Type: application/json" -H "Cache-Control: no-cache"  -d '{"restricted":true,"marquardtRole":"ContentStreamReservedTagMARQUARDTBIWEEKLYUPDATE","description":"Bi-weekly update covering Marquee development and go-to-market functions.","assetClasses":["Commodities","Credit","Currencies","Economics","Emerging Markets","Equities Macro","Equities Micro","Interest Rates","Prime Services"],"authoringDivision":"SECDIV","titlePattern":"(?i)Marquardt Weekly Update.*","name":"Marquardt BIWEEKLY UPDATE", "updatedBy": "d37286ac275911d788f1b1f11ac60222","updated":"'"date +%s"'"}' "http://localhost.abc.com:8000/maq-app-cnts/services/pubs"

Here's the exception I'm getting:

How do I pass the date +%s to curl for proper expansion in bash?

Thank you.

Instead of '... ,"updated":"'"date +%s"'"}', use '... ,"updated":"'"$(date +%s)"'"}' See https://stackoverflow.com/a/30327963/4486184
